Product Description

Semi-Conducting Two Layers Heat Shrink Tube

Semi-Conducting-Two-Layers-Heat-Shrink-Tube

Model: TLHST

Description

Semi-Conducting Two Layers Heat Shrink Tube (TLHST) 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.

 

Features

>Material: cross-linked polymer, Two Layer.
>Operating temperature: -40℃~100℃.
>Shrink temperature: start at 100℃ and full recovery at 130℃.
>Color: Black.
