Corona resistant enameled copper wire
AC variable frequency speed motor has the advantages of high efficiency, energy saving and easy automatic control. Therefore, the growth rate of variable frequency speed control motors at home and abroad is very fast. The AC frequency conversion technology of the motor requires the motor insulation structure to have high corona resistance and temperature resistance. Among them, the corona resistance enameled wire is effective for optimizing the insulation structure and ensuring performance. One way. Chalco vigorously develops corona-resistant enameled copper wire, and has developed corona resistant enameled round copper wire and corona resistant enameled flat copper wire.
Characteristics of Corona resistant enameled copper wire:
The industry's highest heat resistance rating of 220 degrees
Longest anti-corona life in the industry
Significantly improved oil resistance (oil-cooled drive motor)
Significantly improve electrical characteristics
Significantly improve mechanical properties (scratch resistance, windability)
Significantly increase the slot full rate
Significantly improve the adhesion of dipping paint
High lubrication, high strength, high flexibility
The paint film of the anti-corona rectangular wire is very uniform, with good insulation properties and greatly improved bending
