CONTRACTION TUBE FOR CABLE INSULATION JOINT

摘要

6), whose radius is smaller than that of the contraction tube but larger than that of a reinforced insulation layer, then contracted by heating to make a non-conductive portion(1). This heating process starts from the other side of a bended portion(4). The bended portion is made by bending one edge of the contraction tube before the contraction ending. Another contraction tube surrounds the aluminium pipe and forms a nonconductive portion by heating contraction. These non-conductive portions are overlapped at an insulator and molded to one body.
