ZW20-12 Type Outdoor HV Vacuum Circuit Breaker


General Description

ZW 20 outdoor high-voltage alternating-current vacuum circuit breaker is a new on-pole switchgear of our vacuum circuit breaker series products. Its rated voltage is 12 kV. It applies to places with such voltage level, including overhead lines, industrial and mining enterprises, power stations, substations, etc. Under its normal operating conditions and specified technical parameters, it can satisfy the protection requirements of systems connected with the grid in service. It has good performance in short-circuit making and breaking. It is characterized by automatic re-making, stable operation and long electric life.


Reference standard
