ZW20-12F outdoor high voltage vacuum circuit breaker is an outdoor power distribution equipment with rated voltage of 12kv and three-phase AC 50Hz. It adopts vacuum interpreter and SF6 gas as insulating medium, and is an improved product of ZW20-12F type column vacuum circuit breaker.The operation reliability and stability of ZW20-12F is several times higher than that of the traditional spring operation mechanism in China. The contact resistance of the main circuit is small and the temperature rise is low. So ZW20-12F type outdoor column-mounted vacuum circuit breaker is a maintenance-free product.
