にあるものと考えられている。[Technical Background of the Invention and Problems thereof] In overhead power distribution lines and submarine power lines, breakage accidents may occur due to stress corrosion cracking of the wires during long-term use. The main cause of this is when moisture such as rainwater enters the parts of the electric wires where residual stress is applied through the sheath or the ends of the electric wires.
It is thought that this is caused by covering the wire surface with black rust such as copper oxide or sulfide black rust.

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 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, and as a result, the wire There was a problem in that the covering of the grip part was constricted.

ある。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 coating is too good, The nearby insulation coating layer moves and becomes thinner, creating a constriction.

。[Summary of the Invention] In other words, the present invention provides a method for manufacturing a stranded wire conductor comprising twisting a plurality of copper wires together and applying a rust preventive liquid to the outer periphery of the stranded wire conductor. By using a solution in which benzotriazole and its derivatives are dissolved in a volatile solvent, the above-mentioned conventional problems are solved.

分が白く残るようになる。The rust preventive liquid used in the present invention is preferably one in which 0.5 to 3 g of benzotriazole and 0.1 to 1 g of benzo and triazole derivatives are dissolved in 100 mλ of a volatile solvent.
In particular, 3g of benzotriazole and 0.3g of its derivatives have a great antirust effect. If the amount of benzotriazole is less than 0.5 (1), the oxidation resistance will be poor, and if it exceeds 3 g, it will be difficult to coat the conductor. After the solvent is dried, solids will remain white on the surface of the conductor.
