Heat Shrinkable Moulded Shapes 
Semi Conductive Tubes - INSULTUBE semi conductive
Insultube Semi-conductive are used in High Voltage plastic and paper insulated cable Joints up to 36 kV to provide insulation screen on the build-up insulation over connectors. The semi-conductive Tubings are made from thermally stabilised cross linked semi-conductive polymeric material.
