との間に滑りを生じない撚線導体に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a stranded wire conductor that prevents stress corrosion cracking of strands and does not cause slippage between the strands and an insulating coating layer.

とにあるものと考えられている。[Technical profile of the invention and its problems] Overhead distribution lines (1) In submarine cables, disconnection accidents may occur due to stress corrosion cracking of the wires during long-term use. The main cause of this is that moisture such as rainwater enters from the ends of the sheathed wire into the portion of the wire where residual stress is applied, causing copper oxides, sulfide, black rust, etc. to form on the surface of the wire. It is believed that this is due to the fact that it is covered with black rust.

おった。As a solution to this problem, benzotriazole is dissolved in liquid paraffin and applied to the conductor surface, but this method improves the lubricity between the conductor and the coating, resulting in a loss of insulation. There was a problem in that slipping occurred between the electric wire gripping portion and the sheathing, resulting in a constriction in the sheathing of the wire gripping portion.

る。In other words, when installing a wire, the end of the wire is held by a wire gripping device and pulled with a tensile force of several hundred to eight, but if the lubricity between the splicing conductor and the sheathing is too good, the insulation near the gripping part may deteriorate. The coating layer moves and becomes thinner, creating a constriction.
