Semi-Conductive Heat Shrink Tube (SCHST) is used in Cable Joints upto 36 KV to provide insulation screen on the build-up
insulation over connectors. The Semi Conductive Tubing is made from thermally stabilize cross linked semi-conductive
Polymeric material.
>Material: Cross-linked polymer.
>Operating temperature: -40℃～100℃.
>Shrink temperature: start at 110℃ and shrink totally at 130℃.
>Color: Black.
