4.1.2 Fire Barriers shall be made by encasing the cable trays, conduits, l
wireways, and junction / terminal boxes in a one or three hour fire l
rated barrier system as specified in the design documents.
' Typically one hour rated barriers are used in areas with automatic fire detection and suppression systems. Otherwise three hour rated barriers are required.
4.1.3 The purpose of the Fire Barrier is to prevent damage, during a complete engulfment fire, to electrical cables serving one division of equipment required for safe shutdown of the plant when redundant A safe :hutdown divisions occupy the same fire area. [_3\
l l
4.1.4 Raceway support steel contac' ting raceway" enclosed in a one hour Fire Nrrier shall be wrapped for 9" (-0 /+3") in all directions from the point of contact with the raceway. ,
4.1.5 Raceway support steel contacting raceway enclosed in a three hour Fire Barrier shall be wrapped for 18" (-0"/+3") in all directions from the point of contact with the raceway.
4.1.6 When the raceway to be wrapped is attached to a support for multiple raceways, only the support is to be wrapped and not the adjacent conduits that may be within 9 or 18 inches of the wrapped raceway.
4.1.7 Structural steel need not be wrapped if it falls within the required 9" or 18" envelo'pe.

4.2 FIRE BARRIER CONSTRUCTION i 4.2.1 Fire Barriers shall be the Themal Science, Inc (TSI).THERMO-LAG l 330 Fire Barrier System. -
l l 4.2.2 Prior to installation of Themo-Lag the acceptability of the :
additional weight on the conduit supports is to be verified by IEG, i a PCN sent to NPE Resident Engineering, and approval received. An i EWR shall be used in lieu of a PCN when a DCP is not associated l l
with the installation. The acceptability of the additional weight :
l l of Thenno-Lag on cable trays and wireways will be reviewed by NPE prior to the release of the design package. NPE will also i detemine if any power cable ampacity derating is required. l 4.2.3 Installation shall be in accordance with TSI Technical Note 20684 Revision V. November 1985 (Appendix A to this specification) except i as altered or expounded in the following sections: l c
4.2.3.1 In lieu of TSI details shown on figures VI-1, VI-2, and j i
VI-3 in Technical Note 20684, the THERMO-LAG shall be ;
butted to the penetration seal and the joint caulked with ;
trowel grade.THERMO-LAG 330-1. 1 4.2.3.2 The top and bottom of cable tray enclosures should be sealed with 2" of stress skin-(1" on each side of seam), j staples and trowelable 330-1. !
1 I 4.2.3.3 Edges of boards and/or prefabricated conduit sections l should be pre-caulked with 330-1 whenever possible. -Seam i shall be sealed with 330-1 if not pre-caulked.
4.2.3.4 Stagger joints of boards and prefabricated sections l ahenever possible.
4.2.3.5 When a raceway support is attached to an embedded strut, seal off the strut with Thermo-Lag at a location adjacent to the support / strut connection. It is not necessary to extend the required 9 or 18 inches on to the embedded strut.
4.2.3.6 When a cable free airs into a wrapped cable tray, the cable is to be Thermo-Lagged for a distance of 9" or 18" as required. The Thermo-Lag shall extend from cable tray to the steel conduit so that the cable is-not supporting the weight of the Thermo-Lag.
4.2.3.7 Boxing in conduits using prefabricated Themo-Lag sheets as opposed to using preshaped conduit sections is acceptable as long as electrical separation requirements are met.
l l .- - . . -- . - . , -
F-1000 Revision 3 Page 6 of 8 4.2.3.8 The ma,timum length of Thermo-Lag on any adjacent raceway :
which contains power cables and is not scheduled to be wrapped is 18".
4.2.3.9 Cable Tray covers are to be removed for future pulling purposes. Banding is required where tray covers have been removed. Previously installed Fire Breaks may be removed from inside of trays to facilitate future cable pulls.
4.2.3.10 At locations where Themo-Lag interfaces with existing Knowool wrap the following transition procedure shall be used.
a) Pull Kaowool back 6 to 10 inches to expose transition point.
b) Fill interior of tray or coat conduit with a minimum of 8 inches intumastic coating (minimum 4 inches on each side of transition point).
c) Reinstall Kaowool back to the transition point.
d) Thermo-Lag unwrapped portion of raceway to meet the Knowool at the transi ion point.
e) Install minimum 8 inch wide band of Thermo-Lag (minimum 4 inch on each side of the transition point) over the Kaowool/Thermo-Lag transition point.
Thickness of Themo-Lag band shall be equal to the thickness of the Thermo-Lag on the wrapped raceway section.
f) Caulk the edges of the band on both sides with trowel grade Thermo-Lag 330-1.
4.2.3.11 Maximum 12" spacing for cable tray bands may be increased to 30" in cases where interferences dictate. When 12" spacing is exceeded, one piece of THERMO-LAG shall be used and bands shall be placed near each end of the single piece of THERMO-LAG. Also the edges shall be sealed with stress skin and trowelable THERMO-LAG.
Construction Department Administrative Procedure CDAP-00-018 shall be used to control deviation from the 12" criteria.
4.2.3.12 ,In the case of any discrepancies between this specification and TSI Technical Note 20684, the specification shall govern. Such discrepancies shall be brought to the attention of the Supervising Engineer-NPE Civil & Design Analysis Group.

TSI TECHNICAL NOTE 20684 THERMO-LAG 330 FIRE BARRIER SYSTEM INSTALLATION PROCEDURES MANUAL POWER GENERATING PLANT APPLICATIONS SECTION I INTRODUCTION The details of the installation procedures described in the following pages represent Thermal Science, Inc's recommendations for installing the THERMO-LAG Fire Barrier System Designs.
A. GENERAL DESCRIPTION This section describes the THERMO-LAG 330 Fire Barrier System and its five (5) l basic designs. The System is used in power generating plants to protect cable l trays, conduits, cable drops, instrument tubing, junction boxes, pu11 boxes, l condulets, structural supports, hangers and fire damper frames.
i B. FIRE BARRIER DESIGNS Five (5) basic designs of the THERMO-LAG 330 Fire Barrier System have application in power generating installations. These five designs are:
..... Prefabricated Panel Design .....
..... Prashaped Conduit Section Design .....
..... Direct Spray Over Stress Skin Design .....
j ..... Direct Spray-On Design .....
..... 330-660 Flexi-Blanket Thermal Barrier Design .....
l Each of these basic designs have been installed in a number of plants throughout the United States and overseas.
l I-1
l 1
The material components of the first three designs are identical. They are
, comprised of THERMO-LAG Stress Skin Type 330-69 and THERMO-LAG 330-1 Subliming Material. The only difference between these three designs is that tha first two (2) are prefabricated or preformed at the factory, while the third is field sprayed at the jobsite. The Direct Spray-On Design differs from the other three designs in that it does not include the Stress Skin component. The THERMO-LAG 330-660 Flexi-Blanket Thermal Barrier Design is completely different since it is comprised of a heat blocking thermal catalizer reinforced on both '
sides with a low density fiberglass cloth.
The following paragraphs describe each design and highlight the steps involved in installing these designs. More detailed sequential installation procedures are described in Sections II through VII of this Installation Procedures Manual.
l I. THERMO-LAG Prefabricated Panel Design ;
(a) Composition A THERMO-LAG Prefabriested Panel is comprised of THERMO-LAG Stress Skin Type 330-69 and THERMO-LAG 330-1 Subliming Material. These panels are normally supplied in 4 foot by 635 foot sheets, and manufactured in 30 minute, one hour and three hour fire rated designs as follows:
..... A 30 minute design consists of an inner layer of THERMO-LAG Stress Skin Type 330-69 and an outer layer of 0.250 inch minimum dry film thickness of the THERMO-LAG 330-1 Subliming Material.
..... A one' hour design consists of an inner layer of THERMO-LAG Stress Skin :
Type 330-69 and an outer layer of 0.500 inch minimum dry film thickness of the THERMO-LAG 330-1 Subliming Material. 1

l I i (b) Installation Details i
i The fabrication of the Stress Skin envelope involves cutting the number of ,
4 sections of Stress Skin required to form the envelope, and then mounting these l i
sections on the entity to be protected, using 18 ga. minimum stainless steel l I
l tie wire, 0.5" x 0.020" minimum stainless steel banding material, staples or other approved fasteners. The installed sections of Stress Skin are then spray 1 coated with the specified wet film thickness of the THERMO-LAG 330-1 Subliming Material required to produce a 0.500 inch minimum dry film thickness for the one hour fire rated design and a 1.00 inch minimum dry film thickness for the i chree hour fire rated design. An outer layer of Stress Skin is mounted over l the cured subliming material in the case of the three hour fire rated design only.
As an alternate, the fabricated sections of Stress Skin may be spray coated prior t) mounting. In either case, the coating must be spray applied in accordatee with instructions given in other sections of this Installation 4 Procedures Manual. The Direct Spray Over Stress Skin Design is used where the
- overspray protection requirements are not a consideration, and is used to protect cable trays, conduits, cable drops, instrumentation tubing, junction boxes, pu11 boxes, condulets, structural supports and hangers.
l
$ IV. Direct Sprav-On Design i

i FOR PROTECTION OF CABLE TRAYS l l
i The three (3) basic designs of 'the THERMO-LAG 330 Fire Barrier System, used to :
provide thermal protection for cable trays installed in power generating .
plants, are: !
....... Prefabricated Panel " Ready Access" Design ......
....... Direct Spray Over Stress Skin Design ......
....... Direct Spray-On Design ...... ;
l The material components of the first two (2) designs consist of THERMO-LAG ;
Stress Skin Type 330-69 and THERMO-LAG 330-1 Subliming Material. The'only diff.irence between these two (2) designs is that the Prefabricated Panel Ready Access Design is prefabricated at the factory and the Direct Spray Over Stress Skin Design is field sprayed at the jobsite.
The Direct Spray-On Design is comprised of THERMO-LAG 330-1 Subliming Material which is also sprayed at the jobsite and but does not include the THERMO-LAG Stress Skin Type 330-69.
The following paragraphs set forth the sequential steps involved in installing these three (3) designs.
I l
II-1 I
I
- 1. 'O PREFABRICATED PANEL READY ACCESS DESIGN FOR CABLE TRAYS Installation of the Prefabricated Panel Ready Access Design to cable trays involves cutting the number of sections required to form the Fire Barrier from one or three hour fire rated THERMO-LAG Prefabricated Panels, forming the Fire Barrier sections by making 90 degree bands, and then mounting the sections on the cable tray to be protected using 18 ga. minimum stainless steel tie wire or 0.5" x 0.020 inch minimum stainless steel banding material.
The forming of the fire barrier sections is accomplished using one of several methods. Three (3) and four (4) sided one (1) piece sections are formed by scoring, in the case of one hour fire rated panels, or by cutting a "V" groove, in the case of the three hour fire rated panel, along the lines where bends are to be made and then making the required 90 degree bands. The sections are then completed by tieing or banding the sides together and filling in the scored or "V" cut corners with THERMO-LAG 330-1 Sub11 ming Trowel Grade Material. ,
In the other alternative method, individual top, bottom and side pieces are either butt or miter cut from the one or three hour fire rated panel and are then tied or banded together. The seams and joints of the section are then filled using THERMO-LAG 330-1 Subliming Trowel Grade Material.
The sequential steps involved in installing this fire barrier design are described in the following paragraphs. l 1.1 Installation of the One Hour Ready Access Fire Barrier Design 1.1.1 Cut a piece of material large enough to form the bottom caction from a one hour fire rated Prefabricated Panel. The width of the bottom section shall be equal to the sum of the base and both flanges, plus both sides of the cable tray. The length of the bottom section shall not exceed 6.5 feet, since longer sections are unwieldy and more difficult to' install.
1.1.2 Form a rectangular shaped bottom section by making two (2) 90 degree bends which provide for the side panels. The section shall be formed with the Stress Skin Side on the inside.

L i
i l- 1.1.3 Cut a piece of material large enough to form the top section from a i
- one hour fire rated Prefabricated Panel. The width of the top section shall be equal to the base, plus both flanges of the tray, plus the 2
thickness of each of the two (2) sides of the bottom rectangular j i section. !
l l
i
- 1.1.4 Mount the rectanguist shaped bottom section on the cable tray using i l 18 ga. minimum stainless steel tie wires or 0.5" x 0.020" minimum j l stainless steel bandi'ng material as shown in Figures 11-1 II-2 and d II-3, following this page. The recommended maximum spacing between -
l the tie wires shall not exceed 12 inches.
l l 1.1.5 Attach the flat top section with the stress skin side on the inside '
i to the installed pottom section using.18 ga. minimum stainless etwel ;
j tie wire or 0.5" x 0.020" minimum banding material at a maximum .
i recommended spacing of 12 inch intervals as shown in Figures II-4 and i i II-5.
i :
} 1.1.6 Attach additional top and bottom sections to previously installed I sections by butt joining them together at their ends. l OR AS AN OPTION "
i l 1.1.7 Cut individual pieces having either butted or miter cut edges large .
j enough to form the botte,m, sides and top section'from a one hour fire
- rated Prefabricated Pacal.
1.1.8 Mount the botton, side and top pieces on the cable tray using 18 ga.
j minimum stainless steel tie wire or 0.5" x 0.020" minimum stainless
! steel banding material. The recommended maximum spacing between the .
- tie wires shall not exceed twelve (12) inches. j i;

, 1.0 PREFABRICATED PANEL DESIGN FOR JUNCTION BOXES, PULLBOXES. AND CONDULETS j
i Installation of the Prefabricated Panel Design to junction boxes, pu11 boxes, I and condulets involves cutting the number of sections required to form the Fire Barrier from one or three hour fire rated THERMO-LAG Prefabricated Panels, j forming the fire barrier sections, and then mounting the sections on the entity to be protected using 18 ga. minimum stainless steel tie wire or 0.5" x 0.020" minimum stainless steel banding material.
j The forming of the fire barrier sections is accomplished by using one of several methods. Two (2) and three (3) sided one piece sections are formed by 4 scoring, in the case of one hour fire rated panels,'or by cutting a "V" groove, j in the case of the three hour fire rated panel, along the lines where bends are l
co be made and then making the required 90 degree bends. The fire barriers are then completed by tiains or banding the sections together and filling in the l 4 scored or "V" cut corners with THERMO-LAG 330-1 Subliming Trowel Grade i Material.
) In the other alternative method, individual top, bottom and side pieces are either butt or miter cut from the one or three hour fire rated panel and are i
j then tied or banded together. The sesas and joints of the section are filled j using THERMO-LAG 330-1 Subliming Trowel Grade Material.
! The sequential steps involved in installing this fire barrier design are described in the following paragraphs.

TSI TECHNICAL NOTE 20684 SECTION VII THERMO-LAG 330 FIRE BARRIER SYSTEM COATING APPLICATION TECHNIQUES 1.0 THERMO-LAG 351-2 PRIMER APPLICATION I
a l
l 1.1 Prepare the surface of the steel entity for application of the l
THERMO-LAG 351-2' Primer by removing any dirt, scale, rust or .
other contaminants, using hand or sechanical cleaning methods. Never I apply the primer directly over any hard or glossy painted surface j l without roughaning the surface in accordance with standard painting i j practices, j 1.2 Make sure that the cleaned surface is compatible with the THERMO-LAG 330-1 Subliming Material by making cross hatch ,
adhesion tests as follows:
l
............... Cross ~ Hatch Adhesion Test' ...............
The primer is cut over an area approximately 4" by 4" in a square ;
matrix, with each square being approximately 1/2" by 1/2". A high !
quality tape is applied diagonally to the square. Upon completion of the tape application. it is rubbed in firmly to assure good adhesion. With ca. 09mplete jerking motion, the tape is- removed. >
If more than 3 percent of the. Primer is removed from the surface, ,
the application is. faulty. This test should be performed _in areas {
which are deemed critical and in as many places as. required by the i specification. Upon completion of the Cross Hatch Adhesion Test, j the test areas should be coated again with the THERMO-LAG 351-2 Primer ,
by either brushing or light spraying. - l Always apply a barrier coat of the THERMO-LAG 351-2 Primer over )
steel surfaces which have~been previously primed with a zine based primer. All doubtful surfaces should be removed.using mechanical cleaning methods.
VII-1
,I
I h -
e F .
1.2 Apply the Primer to the properly prepared steel surface in one continuous coat using spray equipment, brush or roller. The minimum acceptable dry Primer thickness should be 0.002 inches which is normally achieved by applying a spread rate oficirca 200 sq.,ft.
per gallon.
t l
1.3 Measure the Primer thickness using an approved magnetic (non-destructive) direct reading gauge.
1.4 Make cross hatch adhesion tests on the primed surface to assure proper adhesion between the Primer and the surface of the steel item prior to proceeding with the application of the THERMO-LAG 330-1 Subliming Material.
1.5 Coat the primed steel surface area with the THERMO-LAG 330-1 Subliming Material. The coating shall be applied in accordance with procedures set out in Paragraph 2.0 of Section VII herein.

2.0 THERMO-LAG 330-1 SUBLIMING MATERIAL - SPRAY APPLICATION ;
t 2.1 Apply the THERM 0-LAG 330-1 Subliming Material over a properly prepared f surface. Make sure that.the surface to be coated'is clean, dry, above '
40F and free from scale, rust or other contaminants. ;
2.2 Apply the material in as many passes as required to provide the !
required dry film build of the coating thickness, taking care to l avoid slumping or sagging of the coating. Normally, a minimum dry film thickness of 0.500 inches is accomplished by applying three (3) wet coats of 0.255 inches. However, the thickness which can be !
safely applied in a single pass will depend on the temperature, I humidity, and other fa.ctors that are best determined on the jobsite. !
g ,
2.3 Apply the material in smooth even passes, taking care to keep the ;
spray gun fan pattern at a 90 degree angle whenever possible.-
- Reaching with a spray gun will cause the spray pattern to vary from the 90 degree angle and will result.in a rougher surface than normal. .
2.4 Take frequent wet thickness measurements during the application using '
a non-destructive penetration measuring device to ensure that the >
coating is being applied uniformly and at the required wet film 4 thickness. These wet thickness checks shall be made every five (5) ;
square feet or every two (2) running feet of coating eurface area.
(Note: When taking measurements, allow for a shrinkaga rate of circa 25% between the wet and the desired dry film coating thickness.) i 2.5 Remove excess build up of coating material at edges and joints by brushing or rolling the surface with a damp sponge roller or a nylon bristle brush.
2.6 Spray edges of the substrate from each side to cause the material to wrap around the edge. If the edge coating is not completely closed, use a wet roller or trowel to seal the edge surface.
2.7 Remove all runs, sage, drips or other surface imperfections before the material cures, using wet sponge rollers, brushes or hand trowels.

7.0 REPAIR PROCEDURES l i
l The repair of a damaged section in a THERMO-LAG 330 Fire Barrier.is easily l accomplished by cutting out and. removing the damaged material, and then filling l in the cut out section with new material. l l
7.1 The first step in this procedure is to remove the damaged and loose j material using a knife and scraper. Care should be exercised.that ;
the damaged material is cut back until sound adhering material is !
reached. l 7.2 The next step is to undercut the edges around the cut out section to j fom a beveled edge. All foreign matter is then removed from the :
exposed substrate surface in the cut out section. l t
7.3 The THERMO-LAG 330-1 Subliming Material or THERMO-LAG 330-1 Subliming ;
Trowel Grade Material is sprayed or trowaled into the cut out section. l If necessary, several coats can be applied to achieve the desired fila j thickness. Care should be taken to allow for shrinkage of the repair !
patch by building up a slight done shape on the surface of the patch. j l

l 8.0 CABLE REPLACEMENT PROCEDURES The replacement of a cable in a I N LAG 330 Fire Barrier is accomplished by !
removing sections of the fire barrier, replacing the cable, and then reinstalling the sections.
8.1 The first step in this procedure is to remove the required number of fire barrier sections by cutting away the material at the edges and the butt flanges.
8.2 Next, the stainless steel tie wire or banding material is cut and the:
fire barrier section removed from the cable raceway.
8.3 After the defective cable has.been replaced, the fire barrier' sections are reinstalled, using 18 ga. minimum stainless steel tie wire or 0.5" x 0.020" minimum stainless steel banding material. A coating of the THERMO-LAG 330-1 Sub1'ining Trowel Grade Material is then applied in the specified wet film thickness.co the edges and joints of the [
reinstalled sections, using a trowel or stiff bristle brush, to fill in 8 any uncoated areas.
i I
9.0 POST APPLICATION PRACTICES A clean and orderly condition shall be maintained in the installation area.
Following the application, all debris and equipment, and any overspray, shall be removed and the area left in a condition acceptable to the owner.

_ INTRODUCTION: i Concern has been expressed by the Nuclear Regulatory '
Commission (NRC) for the protection of the circuit integrity of power and control cables in the event of a fire within a nuclear power generating station. Specifically, protection of the redundant control circuits is of interest. In the event of a i fire, although control cir'cuits may become inoperative, th~e protected redundant control circuits should retain their electrical integrity. '
The purpose of this investigation was to obtain information on the performance of certain electrical raceway systems protected-by ceramic fiber blanket insulation, and perlite-cement insulation, when subjected to a controlled fire exposure. The i data obtained are intended for use only by Georgia Power and the Bechtel Corporation for submission only to the Nuclear Regulatory Commission.
l The investigation consisted of witnessing four fir-, tests at the facility of Babcock & Wilcox in Augusta, Georgia. Each test -
was conducted with one protected cable tray and one protected conduit system as shown in ILLS. 5-8. Each tray was filled with ,
various sizes and types of cables. However, only one size and type of cable was installed into each conduit. All cables were installed forming several circuits to which a low voltage, low current load was applied.
- Each cable circuit was monitored and the time at which failure (i.e., shorting between conductors, or ;
ground) occurred for each circuit was recorded. Each test varied in fire exposure duration.
Details of the installation and test observations and results are recorded herein.

TEST APPARATUS:
]
3 The test furnace employed was a catenary type kiln furnace I with a chamber area for the test sample of approximately 36 in.
i vide, 36 in. deep'and 31 in. maximum height, as shown in ILL. 1.
j Two burners located as shown in ILL.1 provided the flase source j for the furnace.
l Furnace operation consisted of sizing natural gas and combustion air (supplied at about 0.6 in. H 20 pressure) within _
J the burner nozzle. The flame length during normal furnace ;
l operation was approximately 18 in. 'Due to the opposing burning . I j configuration, the hot gases and convective heat swirled upward to l
- the top of the furnace.- Combustion products were vented by !
} natural draft through small holes in the fire brick furnace floor i and into a vertical stack which was ducted to the outside. ;
j An approximate 24 in. wide by 24 in. high opening was formed into the front and rear fire brick walls of the furnace to- I i accommodate the sample raceways.
TEST SPECIMENS:
! Cables - The cables used in this investigation were stranded
! copper conductors which varied in size and the number of
! conductors per cable. Both Okolon conductor insulation /0kolon j cable jacket, and polyethylene conductor insulation / polyvinyl
- chloride cable jacket cables were tested. The identification of 1 the cable materials was on the basis of the information provided j by the test sponsor. The cable sizes and their identification code for test purposes are shown in Table I.

l Cable Trays - Two types of cable trays were employ 4d in this investigation. In Testa 1 and 4, steel fluted back cable trays were_used. The trays were 12 ft long and 18-1/8 in. wide. The tray side channels were 4 in. deep with 3/4 in. flanges, and fabricated from 0.070 in. thick galvanized steel. The 0.055 in.
thick galvanized steel fluted back was 15/16 in. deep and formed with 3 in. wide crests and 1 in. vide valleys, with each flute epaced 6 in. 0.C.

Conduit-Intwotests10ftlong,T'in.diameterschedule40 galvanized steel pipe with 0.215 in. thick walls was used as rigid metal conduit raceway. In the remaining tests, 4 in. ID diameter alum.inua pipe with 0.188 in. thick walls was employed. ;
Insulation'- The insulation installed about the cable tray i and conduit raceways (except in Test No. 4) was a 1 in. thick, l 9.4 pcf ceramic fiber blanket designated as "Kaowool". The insulation installed about the conduit raceway in Test No. 4 was a 1-1/;2 in, thick, 11.8 per rigid perlite-coment material designated as "Kaotemp". 1 Insulation Fasteners - Yarious different devices were used to temporarily and permanently fasten the insulation about the raceways. One inch wide Scotchgard filament adhesive tape was used to temporarily secure various pieces of the ceramic fiber blanket prior to installation of the permanent fasteners.
U-shaped steel brackets of various configurations shown in ILLS. 2 .
and 2A, which were manufetured from 0.131 in. thick, 1-1/2-in. :r vide galvanized steel, were used as permanent fasteners about the hc cable tray insulation. ,
The conduit Kaowool insulation was permanently fastened with steel bands. Two types of steel bands were employed. A Type 316 stainless steel band (1/2 in. vide. 0.036 in. thick), and a coated steel band (3/4 in. wide, 0.031 in. thick) were used with their appropriate buckles and installed with the recommended banding tool. ,
The conduit Kaotemp insulation was' fastened with No. 16 SWG (0.062 in, diameter) steel wire.

CONSTRUCTION OF RACEWAY SYSTEMS: .
( One cable tray and one conduit system were investigated in each test. Various types and number of cable lengths were installed into the cable trays, and one size and one type of cable was installed into the conduits as shown in ILL. 3 and as outlined in Table II.
All cables were cut into either 24 or 48 ft lengths. The 24 ft lengths were installed by routing the cable down the. length of the ,
tray, bending it at midlength and then routing it back to the end of the tray. The 48 ft cable lengths were installed similarly. ,
However, these cables were routed down the length of the trays l four times in lieu of two. Therefore, one 24 or 48 ft length of '
cable was considered as two or four 12 ft lengths of cable within the tray, and usually comprised one circuit as shown in Table II.
One 24 ft length of cable was installed in a similar fashion into each conduit tested and comprised one circuit.
The cables were installed in two layers within the tray. The '
general pattern for cable installation is shown in ILL. 3A.

Adhesive tape was wrapped randomly around each piece to temporarily secure the insulation.
In Testa 1, 2 and 3. two pieces were then wrapped side by side around the tray to form a second insulation layer. The width of the Kaovool . pieces was different than that of the first layer so as to provide an offset between the location of the butt joint in the first and second layers. The ends of each piece were overlapped with the overlap staggered between the first and second layers. Adhesive tape was then randomly wrapped about each piece to temporarily secure the insulation. Details of the insulation installation for Testa 1-3 are shown in ILLS. 5-7.
In Test 4, in lieu of installing a complete second layer of k insulation, a 4 in. wide strip of insulation was placed ove, the first layer butt joint which was located at the midpoint of the tray. The ends of the strip were overlapped 6-1/4 in, r.ad the piece temporarily secured with tape. Additionally, strips were ,
installed outside the furnace chamber near the ends of the insulation. Brackets were installed over these 4 in. strips.
Details of the insulation installation Tor Test 4 ere shown in ILL. 8.

.x The four fire tests were conducted.in accordance with the following test method and observed performance is described below.
METHOD
, One cable tray and one conduit system were inserted through j the furnace chamber as shown in ILL. 9 for each test. The conduit was supported by pipe hangers located outside and approximately 2 in. away from the front and rear surface cf the furnace. The
~
cable tray was supported by the furance walls and an independent
, stand outside of the furnace chamber. Location of the raceways i within the furnace is shown in ILL. 9. The remaining furnace j opening about the specimens was filled with Knowool, the ends of l the conduit stuffed with Knowool, and space between the cables l .fikled with fire brick dust.
, (N. Eight Type K thermocouples were installed in various locations as shown in ILLS. 10, 12, 14 and 16. One Type B j thermocouple was used to monitor the furnace temperature and was located approximately 1 to 2 in. above the tray along tFs i
! centerline of the furnace, 15 in. from the rear furnace wall.
a The furnace was controlled by feedback from the furnace ,
thermocouple. It was planned that the measured furnace l temperature for each test be in accordance with the standard temperature-time curve as described in ASTM E119 " Fire Tests of '
- Building Construction Materials."
i i Power (220 v) was supplied to each cable circuit as shown in i - ILL. 4. One circuit breaker was installed for each circuit.
j Circuit integrity was monitored by visual observation of l incandescent light bulbs. Two light bulbs were provided for each j circuit as shown in ILLS. 4 and 9A. The lights were connected in
, parallel so as to provide one back-up bulb for each circuit in f osse of failure of the light bulb filament.

i j At the initiation of each test, all circuits were energized.
1 Upon failure of a circuit (i.e., short circuit), the circuit
, breaker tripped and the light bulbs for that circuit were i de-energized. Since there were no furnace windows, visual i observation of the furnace fire and exposed surfaces of the specimens was not possible.
! Throughout each test, temperature measurements and times at s.
which failures of circuits (monitoring light board) occurred were recorded.
RESULTS Furnace Temperatures'- The furnace temperature as measured by !
the one Type B thermocouple for each test are shown in ILLS. 11, !
13,.15 and 17.
Temperatures - The temperatures within and on the cable tray, ;
and witnin the conduit for each test are shown in ILLS. 11, 13, 15 and 17.
(- Circuit Failure - The times at which circuit failure occurred are presented for each test in Tables III-VI.
Post Test Observations - In general, the ceramic insulation appeared to have a brown char near each joint. The Okolon cable jacket material changed to white ash while the PVC cable jacket '
material decomposed exposing the copper sheath and leaving a black residue char. The general appearance of the insulation and cables after the test is shown in ILLS. 18 and 19 h

'~
not be regarded as conveying any conclusion or recommendations on the part of Underwriters Labortories Inc. regarding the acceptability of the construction or performance of the product - -
for recognition by any code or standard or for any other purpose.
In general, small scale. tests individually do not represent
- all facters associated with fire performance under actual field conditions. Accordingly, these test results may not be generally
- applicable. The suitability of this test method for predicting full scale performance presently has not been determined by the Laboratories.
.._ Based upon time to first circuit failure, the protection systems of Tests 1, 3 and 4 provided greater than 30 min of fire ;.
resistance when subjected to a fire exposure as described herein. .
Based upon time of circuit failures, the tray protection systems with two complete layers of insulation protection (except Test 2) provided 11 to 21 min more resistance against fire than the Test 4 tray protection system with only one complete
- insulation layer.
l Since Test 2 differed from Test 3 only by the location of
{ tray insulation fasteners, the fastening method employed in Test 3 provided 50 min more protection than the fastening method employed in Test 2.

l Babcock & Wilcox Kaowoof* Blanket Wrap Mrs Protection Systems l
l Introduction .
I Since produemg the first Knowool ceramic Sber in 1943 Babcock & Wilcox has responded to ,
industries throughout the world by developing engmeered systems to meet specific needs. One such system is Knowool ceramic fiber furnace linings which replaced dense refractory firebrick linings in the 1960's. B&W Knowool furnace linings are now the accepted stanalard and have resulted in tremendous fuel savings and inaeased productivity. g The same Kaowool ceramic fibers, whieti have been engmeered into high temperature refractory linings for industnal furnaces for over 30 years, are now being used as fire protection for electrical cables by unmana of the Knowool Blanket Wrap System.
l l
l How Did The Kaowool Wrap Systesu Cosme About? d j
l l
I As a result of the Browns Ferry fire in 1975, it was deemed a necessity that the integrity of re-dundant, safety related electncal systems in close r.4 ity be protected during a fire to permit the safe j shutdown of citical processes and equipment. Initially, this was accomplished by providing fire propag- j i
Ction protection for grouped electncal cables. Propagation protection was demgned to prohibit fire from traveling the length of a cable run and spreading from one cable run to another within the same room.
Propagation fire protection systems included: Knowool Blanhat or M Board laid directly on top of cables, various coatings and mastics that were sprayed, troweled or brushed directly on ables; foams and other types of ablative matenals.
While these systems provided an acceptable level of propagation protection, they did not offer suf5cient protection of cables from a prolonged lomlised fire which completely surrounded the cable run.
Thus, the need arose for a fire protection system that was capable of pivvMiag complete. engulf-ment protection for electncal cables found in trays, conduits or channals The system would need to protect the current-carrytag integrity of electncal cables during a fire to allow control of equipment or processes to be maintamed until the fire could be -i' . '-H or brought under control. The system would have to be lightweight so as not to place undue stress on support systems, be flexible and readient so that a could include support members and obstructions along the cable run. The basic matenals found in the system should be noncombustible and not contain levels of l==ehahle components that could corrode cable jackets or stainla== steels. A passive type fire protection system was also de-sired; one that did not depend on fusible links, did not in*=nama=, foam or ablate during a fire.
Babcock & Wilcox responded to these needs for complete engulfment protection by designing the Kaowool Blanket Wrap Fire Protection System.

4 The 1 Hour Kaowoole Wrap System The I hour system consists of two layers of 1" thick,8 lb./ft.:, Knowool Blanket wrapped com.
pletely around the cable run and overlapped at least 3". The butt joint of the inner wrap should be center.
ed under the outer wrap to eliminate straight-through joints.
For trays with no lid and not completely filled with cables, a filler layer of Kaowool Blanket is used to bring the level inside the tray to the tray's height (top).f High performance filament tape is used to secure the Knowool Blanket during installation. The ,
filament tape should be located no more than 4" from the ends of each blanket and not more than 14" apart.
After the two layers of Kaowool ,, ,, , , _ , , ,
Blanket are installed, regular carbon steel # -
j banding material should be placed not -
l l more than 4" from any butt joint on _# , I the outer wrap and not more than 14" C 7y cpart. The banding materialis %" w,
-@ l'rotective outer wide, 0.015" thick, waxed and e------- ----

Aluminized Zetex* Protective Outer Wrap Babcock & Wilcox evaluated various fibrous cloths as protective outer layers in response to concems for the Kaowool Wrap System's potential for tearing under physical abuse, abrading and wicking liquid spills. One product, Almini=4 Zetex Style 800, was found to have excellent resistance to liquid penetra-tion, resistnnee to freeze-thaw degradation and abrasion resistance.
Zeter textile products are made from highly textured E glass yarns which are non. asbestos and can handle temperatures up to 1000* F. During a fire test to 1900* F the Aluminized Zetex cloth fused but did not attack nor react with the Knowool Blanket. It is therefore imperative that the Zetex Wrap be secured ' i independently from the Kaowool Wrap System. The Zetex outer wrap is not intended to provide additional j fire protection but to offer mechanical and weather protection. Babcock & Wilcox can supply Zetex with j an aluminized surface or in an untreated form as required. Aluminized Zetex Style 800 Cloth is 0.060" thick with a standard size roll being 40" wide by 150'long.
Zetex9 is a resistered tradesmark of Newtex Industries. Victor. N.Y. Zetex Textile Products are distributed by the Babcock
& Wilcox Company, insulating Products Division.
Mastic Sealant In those areas where the Kaowool Blanket Wrap Fire Protection System penetrates floors, walls and '
ceilings, fire protection seals should be installed using a martie coating. A recommended coating is Intu-e mastic
- 285, a water-_b ased, asbestos-free, flexible mastic coating, which is manufactured by Carboline Fireproofing Products Division, St. Louis, Missouri. The mastic should be troweled or sprayed completely around the wrapped cable run at the Door, wall or ceiling penetration. The seals should be at least %" thick and extend for a minimum of 8" onto the Kaowool Wrap and the Door, wall or ceiling.

The Kaowool Blanket Wrap Fire Protection System, consisting of high temperature insui&+ ion, may tend to retard the dissipation of heat genented by current carrymg electrical i cables. Testing has indicated that, as a general rule of thumb, instrument and control l cables may be protected with the Knowool System without an excessive temperature rise of g the cables, while power cables may realize excessive temperatures.
i l It is recommended that any design or evaluation of the Kaowool Blanket Wrap Fire Protection System be plant specific, takmg into account all the heat transfer vanables involved:
material, size and geometry of tray, conduit or channel; percent cable fill; current load;
- environment and the thickness of insulation required.
Contact Babcock & Wilcox for assistance in designing the Knowool Blanket Wrap System for fire protection of your electrical cables.
