Description
The Raychem CRSM 107/29-1000 Cable Repair Sleeve is a wraparound heat-shrinkable cable repair system designed for restoring damaged outer jackets of low and medium-voltage power cables without disconnecting or cutting the cable. It provides a fast, reliable, and permanent sealing solution for cable sheath damage, ensuring insulation, moisture protection, and mechanical strength in industrial and utility applications.
It uses a rail-and-channel locking system with a heat-activated adhesive lining that melts during installation to form a watertight and durable seal around the cable.
