Product Overview: The fully automatic single-phase temperature rise test device, HZDL-WS-5000A high-current generator, is suitable for current load tests and temperature rise tests of busbars, switch cabinets, circuit breakers, contactors, current transformers, and other electrical equipment. During normal operation, electrical equipment continuously passes through working currents, converting energy into heat, which causes the temperature of electrical materials to rise. Exceeding a certain range can lead to a decline in the mechanical strength and physical properties of electrical materials, easily causing accidents. Therefore, national standards specify the allowable long-term operating temperatures or temperature rises for different electrical materials.
