TE Connectivity's (TE) Raychem WCSM heat shrink thick-wall tubing is designed for insulation on low voltage cable accessories, as well as for sealing, protection and rejacketing on low, medium and high voltage cables and cable accessories. With 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 application of heat, TE's Raychem WCSM tubing shrinks to the original smaller extruded diameter, fitting tightly over a wide range of cable sizes and cable accessories because of its high shrink ratio. At the same time the tubing's inner sealant wall gives a reliable moisture seal over even the most irregular shapes.
