Model: TLHST
Semi-Conducting/Insulation Double Layer 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.
