ケーブル接続処理方法及びゴムユニット

Cable-connecting conducting method and rubber unit

Abstract

PROBLEM TO BE SOLVED: To provide a cable-connecting conducting method, capable of preventing protrusions of foreign substances from adhering to the outer-periphery surface of a cable insulating layer, and to improve the electrical performance of a connecting part. SOLUTION: A rubber unit 8, which is constituted by supporting a rubber insulating tube 10 in a normal temperature constriction type at the outer periphery of a diameter- expanded supporting tube 9 with the diameter expanded, is inserted in the outer periphery of a cable step-stripping edge part 1. A string-like body 11, pulled out of the diameter-expanded supporting tube 9, is passed toward the inside of the diameter- expanded supporting tube 9 so as to avoid a part for passing from an outer semiconducting electrical layer 4 of the cable step-stripping edge part 1 to a cable insulating layer 5 before the contraction of the diameter of the rubber insulation tube 10 starts. An extra part 9B on a disassembly-start end part 9A side of the diameter-expanded supporting tube 9 is disassembled in advance, and the rubber unit 8 is disposed at a prescribed position in the outer periphery of the cable step-stripping edge part 1. The disassembly of the diameter-expanded supporting tube 9 is started, and the diameter of the rubber insulating tube 10 is contracted and is mounted at at least the outer periphery of the step-stripping edge part 1.
