Description
The Raychem CRSM53/1000 Cable Repair Sleeve is a heat-shrink wraparound sleeve designed for repairing and re-jacketing damaged power cable outer sheaths. It provides a fast, reliable, and permanent insulation and moisture-sealing solution for low-voltage and medium-voltage cable systems up to 1 kV. The sleeve uses a wraparound rail-and-channel locking system, allowing installation without disconnecting the cable.
It is widely used in power distribution networks, industrial installations, underground cables, and utility maintenance systems to restore cable integrity and mechanical protection.
