INSTALLATION PROCEDURE FOR INSULCD/HEMYC CABLE TRAY PROTECTION SYSTEM STRAIGHT SECTIONS B
1.0 PURPOSE The purpose of This Procedure is to assure that the installation of the INSULCO/HEMYC Cable Tray Protection System is consistent with system as tested on the various qualification tests.
The Fire Qualification Test, referenced as B&B CTP-1026, consisted of a One (1) Hour Fire Exposure, y
per ASTM E-119 criteria, including hose stream test in accordance with j
the AMERICAN NUCLEAR INSURERS Information Bulletin No. 5(79) entitled, G
"ANI/MAERP STANDARD FIRE ENDURANCE TEST METHOD TO QUALIFY A PROTECTIVE E
ENVELOPE FOR CLASS IE ELECTRICAL CIRCUITS".
W5B 2.0 SCOPE This Procedure provides the methods and guidelines to be utilized for M
the installation of INSULCO/HEMYC Cable Tray Protection systems.

BASE - slotted and drilled, formed plate used in assembly of locking g
clamp.
m BLANKET - a fireproof product consisting of ceramic fiber material sewn
~
into an envelope of fireproof fabric.
BRACKET - galvanized "C" used in conjunction with a base and U-bolt to make a locking clamp.
FENDER WASHER - a flct washer approximately 1t" 0.D. with a small inside hole to slip over rail studs.
The function is to prevent or minimize damage to blanket by the locknut and to provide more blanket support.
FRNEWORK - an assembly consisting of four struts and four clamps (friction or locking) that surrounds the cable tray, ncrrally spaced on 18" centers.
FRICTION CLA W - pre-galvanized device used to connect framework to cable tray.

'B & B INSULATION, INC, ISSUE:
B ISSUE PAGE: 3 of 13 11/29/82 LOCKING CLANP - galvanized assembly similar to friction clamp but that is tightly bolted to the cable tray to prevent movement of the framework during seismic event.
LOCKNUT - a specially designed, vibration resistent nut having a plastic insert on or near the threaded portion.
These are used primarily on the locking clamp and the rail studs.
RAIL - long sections of strut with threaded anchor studs welded to it.
These are attached to the frameworks parallel to the tray.
Rails pro-vide anchors to secure the blanket system and add longitudinal support to the framework.
y SPRING NUTS - a specially designed rhomboid shaped nut with a spring s
permanently attached that is used to secure clamps to the struts.
O
{
STRUTS - lightweight, pre-galvanized channel used to provide structural 8
support to the blanket system.

t 6.2.5 Insert spring nuts into rails on approximate 18" centers.
6.2.6 With the framework sections placed on approximate 18" centers 1", attach rails using bolts and lockweshers.
6.2.7 Check to ensure that side struts are flush (il") with the rails and firmly tighten bolts to secure side struts to
+
clamps.
6.2.8 Firmly tighten bolts to secure rails to clamps.
6.2.9 Remove gaps, if any, between rails and horizontal strut by pulling on opposing side strut or rail and firmly tighten w
bolt to secure horizontal struts.
i5 g
6.2.10 Firmly tighten locknuts on positive clamp U-bolt to secure W
framework.
b 6.2.11 Frameworks may be shifted, if necessary, by loosening bolt m
y to rail, moving framework as required, and retightening bolt.
H 6.3 Blanket Installation b
6.3.1 Assemble materials, blankets, washers, nuts, etc., in area
.(,
d of cable tray to be protected.
B 6.3.2 Orient blankets in proper relation to cable tray.
z 2
6.3.3 Attach side blankets to top rails by forcing blankets ontn E
studs (Use of pointed instrument such as a punch to start E
holes in blanket is suggested).
Ensure that the edge of the S
blanket extends toward the center of the tray at least 2" j
past the edge of the studs, remove and re-attach blanket if necessary.
(See Figure 5).
m 6.3.4 Install bottom blankets onto bottom rails.
This is easier if
~
both sides are done at the same time working from one end.
Use fender washers, locknuts to hold the blanket onto the studs temporarily.
Do not tighten the locknuts or damage the plastic insert.
(See Figure 6).
6.3.5 Attach lower end of side blankets to bottom rail.
This is best accomplished by removing, one at a time, a fender washer and locknut supporting the bottom blanket, forcing the side blanket onto the stud and re-installing the fendar washer and locknut.
Make sure that the side blankets extend a minimum of 2" past the studs.
(See Figure 7).
6.3.6 Place top blanket on top of franeworks approxiraately centered.
Push blanket onto studs and install fender washers and locknuts.
(See Figure 8).
6.3.7 Tighten locknots onto studs until the blankets are compressed approximately 1/2".
