HP-DWT(SC) Dual Wall Tubing with Semi-Conductive Tubing outside
■ Application:
Heat shrinkable Semi-Conductive Insulation Tubing is dual wall heat shrinkable tubing which inner layer is made from insulation material to provide high insulation and external layer is made from semi-conductive materials to provide electric shielding. The tubing manufactured with special technology, is very suitable for applications in power cable joints up to 36kV.
■ Characteristics：
●Material: cross-linked polymer, Two Layer.
●Operating temperature: -40℃～100℃.
●Shrink temperature: start at 100℃ and full recovery at 130℃.
●Color: Black.
