ELE-3COP-361 Title – Application of RaybraidTM and InstaliteTM Braid to Hand Laid cables. Before starting work please read this document carefully and note the guidance given. 1 Purpose and Scope This COP describes the procedure to be used when installing both single and double layers of RaybraidTM and InstaliteTM Braid. The instructions in this document take preference over IPC/WHMA requirements, as do the drawing and any customer documentation. 2 Performance Objective This code of practice is produced to support operators already trained in the installation of heat shrinkable and harnessing products. It identifies the procedure to be used when installing both single and double layers of RaybraidTM and InstaliteTM Braid to a cableform to give 3600 screening. RaybraidTM is supplied in two product types, RAY-90. Standard tin plated copper shield with 90% optical coverage. RAY-10X. Available in tin plated copper (RAY-101) or nickel plated copper (RAY-103) for high temperature application with 93% optical coverage. InstaliteTM Braid is supplied as LWB-10X. Available in tin plated copper alloy (LWB-101) or nickel plated copper alloy (LWB-103) for high temperature application with the coverage specified on the SCD. RaybraidTM and InstaliteTM Braid are supplied on a tube former which facilitates assembly and is more robust than shield provided in flattened form. 3 Materials and Equipment: Cable to be shielded Raybraid™ or InstaliteTM Braid of the appropriate size. See Section 6 or SCD for InstaliteTM Paper Adhesive Tape Cord Gloves Holding Fixture (Small Bench Vice) 4 Health and Safety Adhere to local Codes and Regulations relating to Safe Working practices. For the U.K. adhere to requirements of the Health and Safety at Work Act 1974 and subsequent amendments. Always wear gloves when pulling shields tight. 5 Procedure Using paper adhesive tape attach the end of the cable to be shielded, to the end of the Raybraid™ or InstaliteTM Braid former tube. Feed the Raybraid™ or InstaliteTM Braid off of the former onto the cable. When all of the braid is fed onto the cable remove the former and paper tape from the cable.

Secure this end in the holding fixture. Wearing cord gloves and starting from the clamped end, pull the Raybraid™ tight onto the cable and twist the free end of the shield (InstaliteTM Braid twist and tape) to lock into place Remove from the holding fixture. For double shields using the paper adhesive tape attach the former of the second shield to the cable. Feed the braid off of the former on to the cable. When all of the Raybraid™ or InstaliteTM is fed onto the cable remove the former and paper tape. Pull the end of the braid over the end of the cable and twist to lock into place. Secure this end in the holding fixture. Wearing cord gloves and starting from the clamped end, pull the braid tight onto the cable and twist the free end of the shield (InstaliteTM Braid twist and tape) to lock into place Remove from the holding fixture 6.

Inspection Requirements Ensure strands are not scraped, nicked, severed, flattened, untwisted, buckled, kinked or otherwise deformed. Ensure that the Raybraid™ or InstaliteTM Braid is pulled tight onto the ELE-3COP-361 Revision 6 Page 2 of 3 ELE-3COP-361 Title – Application of RaybraidTM to Hand Build Cables. cableform and there is no bird caging. Weave of Raybraid™ should be consistent and of even coverage. 8.
