Product Description
Outdoor 33kV 35kV 1250A Vacuum Circuit Breaker With Transformer:
ZW 32 outdoor high-voltage alternating-current vacuum circuit breaker is a new outdoor high-voltage alternating-current switchgear of our vacuum circuit breaker series. Its rated voltage is 33/35 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 system protection requirements of the grid. It is characterized by automatic re-making, stable operation and long electric life.
Advantages
1.Simple structure.
2.Adaptultra low resistance typevacuum interrupter.3.Adaptoptimization and modularspring operating mechanism.4.Suitable for occasions withfrequent operation.5.Free maintenanceandlong service life.
6.Highreliableperformance.
