This heat shrink cable repair sleeve is made of polyolefin. With a unique wraparound design, it is intended to be used as insulation materials on cables up to 1000V and as jacket repair materials on cables up to 35kV. The inner wall has been coated with adhesives that, when being heated, will help make a safe and watertight bond with cables. In addition, a metal clip has also been applied to fully seal the cable repair sleeve.
