Heat Shrink Three Way Semi-conductive Cable Breakouts provide envirnmental seal to the cable crutch of 3 Plastic and Paper insulated cables rated upto 36kV. The Breakouts are made from thermally stabilised cross linked semi-conductive polymeric material.

The Breakouts are interally coated with water resistant mastic.

These breakout are specially used for 11kV PILC Belted cable to seal the crutch area as well as to provide individual screen to each core.
