LV & MV Cable Repair Joints
PWASR Wraparound sleeves close easily with a permanent locking system that consists of a raised rail profile and a stainless steel channel. These sleeves are mainly used as insulation for 1C low-voltage power cables and for rejacket repair up to 66 kV or for general sealing applications. Hot-melt adhesive provides a secure environmental seal. They also have an unlimited shelf life, when stored under normal conditions.
