Heat
Shrink Semi Conductive cable breakout are
used for PILC belted cable to seal the crutch
areas as well as to provide individual screening
to each core. The breakouts are made from
high quality cross linked semi conductive
polyolefin material. The breakouts are internally
coated with water resistant red mastic.
