It can be used to protect charged body with any shape to resolve the lack of relative space, it is used for the repair of damaged cable, the middle joint side sealing of power cable and other problems.
It is made of the heat shrinkable layer and the bonding layer of low melting point polymer composition.
The outer layer shrinks; the inner layer melts when heated to realize seal and insulation integration of a protected charged body.
Wind the materials according to 1/2 overlap, the ends can be fixed with simple tape, heat uniformly with the torch from one side to another side until the inner adhesive exuding uniformly along the overlap after shrinkage, form an unity after cooling.
