Raychem WCSM-70/20-1500 heat-shrinkable Halogen-free Heavy-wall insulating tubing.
Size 70/20 Adhesive Lined Heat Shrink Tubing.
Raychem WCSM is a heat-shrinkable heavy-wall tubing for insulating and sealing power cables and accessories. In this tubing, the electrical and physical properties of a cable over sheath material are combined with ruggedness and easy installation. The material used is halogen-free and UV resistant.
On heating, WCSM tubing recovers to a smaller diameter, fitting tightly over a wide range of cable sizes and accessories because of its high shrink ratio.
Raychem WCSM tubing’s mechanical strength enables immediate back-filling 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.
For use on standard poly- or elastomeric -insulated/jacketed cables or lead-jacketed cables, which may include aluminium or steel armouring.
Use uncoated tubing (-A/U and /U) for cable rejacketing and mechanical protection only.
Connectors over 6 inches: Recommended cut length = connector length + 5 inches.
Connectors up to 6 inches: Recommended cut length = connector length + 4 inches.
WCSM tubing has a 3:1 shrink ratio and an unlimited shelf life when stored under normal conditions.
Tyco Electronics Raychem is one of the world leaders in the technology of heat-shrinkable materials and one of the largest producers of heat-shrinkable polymeric and elastomeric components. By electron beam radiation Raychem materials are given an “elastic memory”. They can then be installed over variously-shaped objects to make a tight, insulating or fluid-resistant cover. In a wide range of formulations, Raychem products are engineered to meet the specific demands of the growing world of energy.
