Abstract

The present invention relates to an insulated electric wire having partial discharge resistance and a partial discharge inception voltage. Specifically, the present invention relates to an insulated electric wire having partial discharge resistance, which not only has excellent partial discharge resistance, The voltage is high, and the adhesion between the conductor and the insulating layer, the flexibility of the insulating layer, etc. are also excellent, and the manufacturing process is simple and the manufacturing cost is low.

Description

technical field [0001] The present invention relates to insulated electric wires, and in particular, the present invention relates to insulated electric wires having partial discharge resistance, which are not only excellent in partial discharge resistance and high in partial discharge inception voltage, but also have adhesion between conductors and insulating layers, The insulating layer is also excellent in flexibility and the like, and the manufacturing process is simple and the manufacturing cost is low. Background technique [0002] Insulated wires include insulation-covered wires such as enameled wires used in coils for electronic equipment such as motors and transformers. When the above-mentioned insulated wire is used in a motor in a high-voltage environment, if the partial discharge inception voltage is low and the partial discharge resistance is insufficient, fine gaps will be generated between the insulating protective film or inside the insulating protective film...
