Product Description
ZW32/3CT 35kV Pole Mounted Vacuum Circuit Breaker:
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.Adapt ultra low resistance type vacuum interrupter.
3.Adapt optimization and modular spring operating mechanism.
4.Suitable for occasions with frequent operation.
5.Free maintenance and long service life.
6.High reliable performance.
