WDWT

Heat Shrink Semi-conductive/Insulation Dual Layer Tube

The red inner layer is made of insulation material to provide good insulation. The black outer layer is made of semi-conductive material to provide electrical shielding. Suitable for applications in medium voltage cable joints up to 42 kV. Shrink temperature: start at 90℃, and fully recovered at 130℃.
