【発明の詳細な説明】 ［発明の技術分野］ 本発明は素線の応力腐食割れを防止した撚線導体の製造
方法に関する。Description: TECHNICAL FIELD OF THE INVENTION The present invention relates to a method for producing a stranded wire conductor in which stress corrosion cracking of a wire is prevented.

ことにあるものと考えられている。[Technical Background of the Invention and Problems Thereof] In overhead distribution lines and submarine lines, 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 the part of the wire where residual stress is applied from the sheath or the end of the wire, causing copper oxide or sulfide black rust on the surface of the wire. It is believed to be covered with black rust.
このような問題の解決策として、ベンゾトリアゾールを

ことも行なわれているが、この方法では、導体と被覆間
の潤滑性が向上する結果、電線把持部の被覆にくびれを
生じさせるという問題があった。As a solution to such a problem, benzotriazole is dissolved in liquid paraffin and applied on the surface of the conductor, but this method improves the lubricity between the conductor and the coating, and as a result, There is a problem that the covering of the grip portion causes a constriction.

装置で保持されて、数百kgの張力で引張られるが、その
とき導体と被覆間の潤滑性が良過ぎるとと把持部近傍の
絶縁被覆層が移動して細くなってくびれが生ずるのであ
る。That is, when laying an electric wire, the end of the electric wire is held by a wire gripping device and pulled with a tension of several hundred kg. At that time, if the lubricity between the conductor and the coating is too good, insulation near the gripping part will occur. The coating layer moves and becomes thin, resulting in a constriction.

It is an object of the present invention to provide a method for producing a stranded wire conductor which has good oxidation resistance and sulfidation resistance, does not significantly improve the lubricity between the conductor and the coating, and therefore does not cause a constriction in the wire grip portion. .

It is preferable that 0.5 to 3 g of benzotriazole and 0.1 to 1 g of a benzotriazole derivative are dissolved, and particularly 3 g of benzotriazole and a derivative thereof having a concentration of 0.3 g have a large rust preventive effect. If the amount of benzotriazole is less than 0.5 g, the oxidation resistance is inferior, and if it exceeds 3 g, the solid content remains white on the surface of the conductor after coating the conductor and drying the solvent.
