付け性に劣るという問題があった。Since the above-mentioned polyurethane insulated wire is inferior in heat resistance, a partially esterimide-modified polyurethane insulated wire or esterimide insulated wire is used in place of this. However, although the ester-imide-modified polyurethane insulated wire has good solderability, it does not have sufficient heat resistance, and the ester-imide insulated wire has excellent heat resistance and solderability. There was the problem of being inferior.

である。Further, in the process of winding a coil for equipment, a high-speed automatic winding machine has been widely used in recent years for the purpose of speeding it up, and accordingly, a high degree of abrasion resistance is applied to an insulating layer of an insulated wire. Therefore, wear resistance and resistance to work deterioration are required.

を生じているものであった。[0006] In order to improve the abrasion resistance and work deterioration resistance of the insulating layer of a conventional insulated wire, an insulating coating is formed by applying and baking an insulating coating material containing nylon 6 or nylon 66 as a main component on the surface layer of the insulating layer. It is known to provide. This insulating film can achieve its purpose because the abrasion resistance is improved because nylon resin such as nylon 6, nylon 66 has a low friction coefficient, but the insulating film is inferior in lubricity when the shock is applied from the outside. There is a problem in resistance to deterioration due to work that is easily damaged.

である。The amount of the curing agent is limited to 3 to 30 parts by weight with respect to 100 parts by weight of the nylon resin. The reason for this is that if the amount is less than 3 parts by weight, it is sufficient for the insulating film. This is because the abrasion resistance cannot be imparted, and when the amount exceeds 30 parts by weight, the plasticity of the insulating film decreases.

る。Further, in the present invention, the film thickness of the second insulating layer is limited to 0.2 to 2 μm. The reason for this is that when the film thickness is less than 0.2 μm, it is not possible to impart wear resistance and heat resistance to the insulating film, and when it exceeds 2 μm, this second insulating layer film is formed. This is because it becomes difficult to carry out soldering without changing the temperature.
