TE Connectivity's (TE) Raychem WCSM heat-shrinkable heavy-wall tubing is designed for insulation on Low voltage cable accessories and applications, as well as for sealing and protection on low, medium and high voltage cables and accessories. In this tubing type, the electrical and physical properties of cable oversheath and core insulation of low voltage cables are combined with ruggedness and easy installation. On heating, TE's Raychem WCSM tubing recovers to the original smaller diameter, fitting tightly over a wide range of cable sizes and accessories because of its high shrink ratio. At the same time the tubing's inner sealant wall gives a reliable moisture seal over the most irregular shapes. TE's Raychem WCSM tubing mechanical strength enables immediate backfilling of cable trenches after jointing. Widely used to insulate, protect and seal power cable joints, accessories and electrical connections, it is one result of our extensive capability in materials technology.
