However, this insulated wire has poor heat resistance, and the number of short circuits after aging increases at high temperatures, making it unable to perform its original function.

である。The heat-resistant life of the above thermosetting resin is based on IEC Pubk17.
The reason why the temperature was limited to 20,000 hours TE12Q'c or more as specified in Section 2 is that if the temperature is less than 120°C, crosslinking will be promoted after high-temperature aging and the short circuit temperature will rise.

ある。Therefore, in the insulated wire of the present invention, the blending ratio of the polyallylsulfone resin and the above-mentioned heat-resistant thermosetting resin is 10 to 100 parts by weight of the heat-resistant thermosetting resin to 100 parts by weight of the polyallylsulfone resin. The reason for this limitation is that if the amount is less than 10 parts by weight, the softening temperature and short circuit temperature under high loads are unstable and tend to decrease, and the appearance of the insulating film during the manufacture of electric wires is inhibited. This is because the linear velocity decreases. Moreover, if the amount exceeds 100 parts by weight, the short circuit temperature after high temperature aging will increase.

It can be obtained by repeating coating and baking several times using the method described above to form an insulating film layer.
