To identify the suitable test conditions for evaluating the compatibility between lubricating oil and polyimide enameled wire, a series of compatibility tests were conducted under varying water content levels and different cycle counts. The tests employed the cold and heat cycle impact method as specified in T/CEEIA 415—2019 "Insulation System of Driving Motor of New Energy Vehicles - Technical Requirements." The enameled wire’s appearance, breakdown voltage, and PDIV were assessed post-test, allowing for the determination of the impact of water and cycling on the compatibility test outcomes.
