腐食等を充分に防止することができなかった。Therefore, in order to prevent black discoloration and corrosion of such derivatives, conventional methods have been used to plate the conductor surface, treat it with a discoloration inhibitor, or add benzotriazole (hereinafter referred to as BTA), a rust preventive agent, to the insulator. (Problems with Background Art) However, none of these methods could sufficiently prevent corrosion of the conductor over a long period of time.

The insulated wire of the present invention has BTA and BTA on a stranded copper conductor.
In the present invention, as the BTA derivative, 1-methylpenztriazole, 5-methyl-1・H-benzotriazole, etc. are used. be able to.

にあるようにするのが望ましい。In addition, in the present invention, the blending amount of B'l'A and the B'I'A derivative is determined when constructing the insulator for the following reasons.
It is desirable that both amounts are in the range of 0.05 to 5 parts per 100 parts by weight of base rubber and plastic (hereinafter referred to as parts).

〜５部配合することが望ましい。In other words, if the blending amount of either BTA or BTA derivative is less than 0.05 parts per 100 m of rubber or plastic, the effect of preventing discoloration etc. will not be sufficient, and on the contrary, if the blending amount of either exceeds 5 parts. In this case, not only no further improvement in the rust prevention effect is observed, but also the electrical and mechanical properties deteriorate, which is undesirable.
It is desirable to mix up to 5 parts.
