- Ampacity of Power C ble Wrap. W/Thermolag inst. as Free Air Dp" oBJECTIVI QI, g&qULATIoJ{
This calculation will determine the installation limit @ ! k associated with wrapping free air drops of power cables with s
Thermolag 330-660.
These limits provide the field the ability to approve a given installation involving power cables without having to che:k ampacity.
The conclusion will state restrictions with regard to the number of cables in the wrap and may make the restrictions contingent on the cables already installed in thermolagged trays, conduig3 etc.
A tiEI)ioDoLOGY w
1.
The ampacity of cables in free air when wrapped with Thermolag 330-660 will be modeled in similar fashion as cables in a conduit.
An air gap between cable and Thermolag is assumed.
References 15, 16, and 17 show how Thsrmolag is applied to cables in free air.
The wrap will not be in contact with the cable, thereby, 4
justifying the similarity of its installation with a conduit.
2.
All thermal resistance values of the cable insulation, between the cable and wrap, of the wrap, and between the wrap and air will be developed using the equations from Reference 3 (J.H. Neher, and M.H. McGrath paper) and Reference 2 (K. Petty paper).
Conservatively, no axisi heat transfer is assumed.
3.
MathCAD cottware will be used to input and arrange the source data which completely describes the cable i
parameters, e.g. conductor diameter, insulation thickness.
These are shown in template - Attachnent A, and the results are saved on a computer file in ASCII A
a for use by the templates Attachments B1, B2, d[D M 221 o
Attachment A will clearly describe the source o
e input data.
MathCADtemplateAttachmentB165bt$lbbwillcalculate 2h 4.
interin values for input into other templates.
Specifically the number of cables and conductors in a bundle, effective bundle diameters, and the maximum number of cables which can fit into a conduit are calculated.
(
f Several conditions will be calculated:
cable bundles consist of 1, 2,
3 or 5 cables, or cable bundles will be the maximum number of cables which can fit in either a 3,
4, 5,
or 6 inch conduit.
NEC definition of 40 percent cable fill in cenduit will be used to calculate the maximum number cf caolog j
d 1
Cable ampacity will be calculated for each possible bundle size discussed above using the approaches I

outlined in Reference 3.
Due to memory limitations this jkg MathCAD template is sub-divided, with the results of ampacity calculation saied on a computer file in ASCIIformatandtransferredtotempla GA 5.
The relationship between the bundle diameter for the cables and the diameter of the individual cables is used in calculating therral resistance between cable wrap and air.
This relationship is defined on template
' /$3 Attachment C and the results saved on a computer file in i
l ASCII format and transferred into template _ Attachments w
B1 and Gl.
6.
The properties of Thermolag 330-660 are taken from Attachment D.
Since the product requires two layers wrapped longitudinally, and each layer must overlap 2 to 4 inches, the total applied thickness will be taken as 4 times the product maximum thickness.
For attachments G1, G2 and G3 product thickness data will be taken from Attachment I.
7.
Some load diversity is considered for cable bundles A
greater than 3 cables, see Assumption No.
5.
Diversity M
factors are developed and documented in MathCAD template i
A tachment F and used in MathCAD template Attachments B1 ancTGl' g The basic approach is to consider that cables 1 and 2 produce heat on the basis of 1.25 times full load current and subsequent cables produce heat on the basis i
of 1.0 times full load current.
A diversity factor is arrived by dividing this offective heat production with that based on all cables producing heat at 1.25 times full load current.
The diversity factor is used in MathCAD template Attachment Bl.
The actual number of conductors in the bundle are multiplied by this generate an effective number of diversityfactor@y()inthethermalresistance conductors for use calculations.

Thermolagged trays-Maintained Space, b) Thermolagged.

These ampacities will be taken from DBD-EE-52, Rev.3.
Tha maximum number of cables in a free air drop which can be contained under the wrap without exceeding the ampacity of the adjoining sections of thermolagged raceway will be clearly shown on MathCAD template Attachments B3, QM e

Accuracy of file transfer between each MathCAD template will be verified by printing the files from templates and comparing results.
Computational accuracy of l
MathCAD will be verified by having the Reviewer perform a manual check of a portion of the complete calculation, selected at random using source data os input.
This manual check is included in this calculation as Attachment E.
10.
Attachments A, al, B2, B3, C, F, Qc2 'G37_and FQ are
~
~
the print outputs of MathCAD, described by Reference 19.
11.
Attachments B1, B2, and B3 cover calculations for Thermolag product thickness of 5/16 inch.
Attachments G1, G2, and G3 cover product thickness of 3/8 inch, 12.
Ampacity results in Attachment G2 were rounded to whole i
integers before ampacity comparison.
This was not done in attachment B2.
Ampacity comparison logic in Attachment G3 uses less than or equal to instead of less than from Attachment B3.
13.
Attachment DB2 uses the PRN file from B1 tr calculate
/ hi ampacity for free air drops.
It adds an e.tra layer of Thermolag for cable bundles less than three inches in diameter, per CPSES-M-2032 Rev. O and DCA 95794 Rev.
6.
Attachment BB3 uses the ampacity from Attachment BB2 and compares it to tray and conduit Ampacity.
14.
In Attachment BB3 Thermolag tray ampacities are based on i
a 40% derating factor instead of 31% as was done in Attachments B3 and G3.
Impacts on power cable size of 40% vs. 31% tray Thermolag derating factor is documented in Calc 2-EE-0053.*
i Thermolag conduit ampacities in Attachment BE3 are identical to those used in B3 and G3.
This is because it covers 3 inch and Aarger size conduits.
The thermolag conduit ampacity for 2 inch and smaller size has been changad( see calc. EE-CA-0000-3250).
ASSUMPTIONS s
1.
Trays and/or conduits are thermolagged on one or both sides.
Conduits could be boxed or shell design.
2.
Cable bundle sizes will vary, but never be larger than the number of cables that would fit in a 6 in, conduit.

3.
An air gap is assumed betwnen the wrap and the cable because the wrap is not flexible.
4.
For maximum thickness of product, 4 " layers" of wrap are assumed.
The wrap is applied longitudinally (eg., cigar wrap, with a 2 to 4 inch overlap for each layer).
Two layers are applied, but conservatively most sections 4
A will have 4 layers because of the overlap.
Also product g
thickness of 5/16 and 3/3 in, will be considered separately.
5.
Load diversity is considered for cable bundles y$h w
centaining more than 2 cables on the basis that third and higher number cables in the bundle carry only 1.0 times full load current at the same time as cables 1 and 2 carry 1.25 times full load. This is a reasonable assumption since:
f a.
DBD-EE-052 re@ ires all power cable to have a minimum ampacity of 1.25 x full load current (FLA).
In practica only a few cables G thp_entireM b.
~1.0 x FLA operate at 1.25 x FLA; the rest operate at or less.
6.
Thermolagged free air drops can be modelled as a conduit in the horizontal plane (conservatively, a model in the vertical direction would produce higher ampacities).
7.
Cable diameters and insulation thicknesses based on ICEA thickness, and conductor diameters will produce i
conservative e.mpacities.
It also produces the smallest possible cable diameter (smaller than that used in the database of CARDS).
8.
The equation for Rsd, thermal resistance between cable A
and thermolag, uses empirically derised constants.
M Since none of the references tested thermolag, the basis r
for selecting these constants had to be established.
These constants are assumed to depend exclusively on the thermal resistivity of conduit (or Thermolag).
Reference 20 supports this by stating "It follows therefore that a considerable variation in B for cables in single-fibre ducts may be expected depending upon the relative thermal resistivities of the duct wall and the surrounding medium, and other data which has come to the author's attention confirms this.
Thus the curve of Figure 3 for fibre duct should be considered as an upper limit."
The following Table has been developed from data contained in Reference 3.
Interpolation of this data on the basis of thermal resistivities is done to develop the A' and B' constants for Thermolag 330-660 used in

Three layers of 3/8" Thermolag are the maximum thickness on cable bundles of less than 3-inches in Attachments BB2 and BB3, resulting in a possible 6 layers due to i
overlap.

ATIACHKENT F DEVEIcfMENT OF AMPACITY DIVEPJiITY FACTORS 1
ORIGIN N 1 As discussed in the methodology, as the number of cable contained within a 9
wrap increases it beccess advantageous to account for diversity of loading.
All power cables are sized per D8D-EE-052, which requires the cables to have a minima ampacity of 1.25 times full load current. In large groups of cables it is practical to consider only a few ". ables are operating at 1.25 times full load current arx1 the remaining cantes are carrying 1.0 times full load current.
This attachment will calenlate the equivalent heat produces by varies number of cable bundle sizes. An equivalent N'- number of cables will be calculated representing equivalent heat production.
N := 1. 10 The ntunber of cables in a bundle.

Heat t= 1.25 N This is heat production per unit I-full load N
