Three Finger Semiconductive Breakouts


Three Finger Semiconductive Breakouts

Heat Shrinkable 3-way Semi-Conductive cable breakouts provide an environmental seal to the crutch of 3 core Plastic and Paper insulated cables rated up to 36kV. The Breakout are made from thermally stabilized cross linked sem-conductive polymeric material.
The Breakout are internally coated with water resistant mastic.
These Breakout are specially used for 11 kV PILC Belted cable to seal the crutch area as well as to provide individual screen to each core.
