Abstract

Provided is an ATF (Automatic Transmission Fluid) oil and corona-resistant enameled wire for electric vehicle motors, belonging to the insulating materials field. The ATF oil and corona-resistant enameled wire for electric vehicle motors comprises a copper conductor and an insulating layer, wherein said insulating layer from inside to outside is composed of ATF oil and corona-resistant protective film, corona-resistant PAI film, ATF oil and corona-resistant protective film, corona-resistant PAI film, ATF oil and corona-resistant protective film. The ATF oil and corona resistant enameled wire of this disclosure is suitable for the preparation of oil-cooled electric vehicle motor loose winding coil due to the advantages of good manufacturability, excellent ATF oil and corona resistance, and low manufacturing cost.
