Scope

Scope: This standard specifies the technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage for corona-resistant polyimide films used in electrical insulation. This standard applies to corona-resistant polyimide films used for motor coil winding materials and electromagnetic wire insulation. Main technical content: In recent years, GB/T 21707 "Insulation Specifications for Three-Phase Asynchronous Motors Used in Frequency Conversion Speed Control" has put forward detailed requirements for equipment and test parameters through extensive testing, promoting the unification of parameters for corona resistance testing equipment in China and ensuring the comparability of data obtained by different instruments. Therefore, the conditions for formulating technical requirements for corona-resistant polyimide films have been met. CRRC Yongji Electric Motor Co., Ltd. conducted research on the application of corona-resistant polyimide films in 2017, exchanged technical information with domestic and foreign suppliers multiple times, and conducted extensive verification. As a result, the mechanical properties and corona resistance of domestic corona-resistant films have been greatly improved. Therefore, based on the performance test data provided by Shanghai Electrical Appliance Research Institute and Guilin Electrical Appliance Research Institute, as well as the corona resistance test times obtained by different corona resistance testing equipment, this standard was formulated. This standard specifies the technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage for corona-resistant polyimide films used in electrical insulation. It is applicable to the performance evaluation of corona-resistant polyimide films used for motor coil winding materials and electromagnetic wire insulation.
