CABLE REPAIR SLEEVE RAYCHEM CRSM84/20-1000

Description

The Raychem CRSM 84/20-1000 Cable Repair Sleeve is a wraparound heat-shrink cable repair system designed for restoring damaged outer sheaths of low-voltage power cables without cutting or disconnecting the cable. It provides a fast, reliable, and permanent solution for cable jacket repair, insulation restoration, and moisture sealing in underground, outdoor, and industrial installations.

This sleeve uses a rail-and-channel locking system with heat-activated adhesive lining, which ensures a tight mechanical closure and waterproof sealing after heating. It is widely used in utility power networks, industrial maintenance, and electrical infrastructure repairs.
