段を講ずる必要があるなどの問題点があつた。(Prior art) Conventionally, in order to reduce as much as possible the conductor axial force caused by temperature rise, the conductor of the conduit aerial cable was
It is composed of multiple stranded wire conductors made by twisting together thin wires of 1.5 mm or less, and when an axial force is generated, the stranded wire conductor curls inside the storage tube so that the axial force can be absorbed. When connecting the stranded wire conductors of a conduit aerial cable configured in this way, conventionally, multiple stranded wire conductors were connected individually with crimp sleeves to prevent wire breakage, or the stranded wire conductors were The conductors were V-cut and individually welded and connected, but in the former case not only a large number of crimp sleeves were required, but
Since multiple stranded wire conductors must be crimped and connected individually, the crimping process takes a long time, and the outside diameter of the connection part becomes significantly large. Not only does the welding work require a lot of effort and a long time to make V-cuts and weld them individually, but it is also necessary to take special measures to prevent spatter during welding from entering the storage pipe. There were some problems.
