Title:
ATF OIL- AND CORONA-RESISTANT ENAMELED WIRE FOR ELECTRIC VEHICLE MOTOR AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/208318
Kind Code:
A1
Abstract:
Disclosed are an ATF oil- and corona-resistant enameled wire for an electric vehicle motor and a preparation method therefor, belonging to the field of insulating materials. The ATF oil- and corona-resistant enameled wire comprises a copper conductor and an insulation layer, wherein the insulation layer includes, successively from inside to outside, an oil- and corona-resistant protective coating, a corona-resistant polyamideimide coating, an oil- and corona-resistant protective coating, a corona-resistant polyamideimide coating, and an oil- and corona-resistant protective coating. The ATF oil- and corona-resistant enameled wire of the present invention has advantages, such as a good application process, an excellent corona resistance, an ATF oil resistance and a low manufacturing cost, and is suitable for the preparation of loose winding coils for an oil-cooled electric vehicle motor.
