Abstract:With the successful convening of the World Conference on New Energy Vehicles in Hainan in July 2019, the development direction of new energy vehicles in technological innovation and other fields has been clarified, the development of new energy vehicles will be accelerated further, which will make the high-heat-resistant grade variable frequency enamelled copper flat wire products for new energy vehicle driving motor be a new growth point in the future enameled wire industry market. According to the current technical development direction of enameled wire products, the production process, technical goals and process routes for the research and development of 220 grade variable frequency enameled copper flat wire for new energy vehicles are formulated, the process technology of 220 grade variable frequency enameled copper flat wire is determined, the conventional performance and the high frequency pulse corona life resistance performance of the developed products are tested, and all the performance fully meet the technical goals of the research and development of 220 grade variable frequency enameled copper flat wire for new energy vehicles.
