SF6 Breakers Insulated Equipment for sieyuan

SF6 Breakers Insulated Equipment for sieyuan

The first generation of SF6 circuit breakers was the lower voltage classes of 72kV and 145kV. As SF6 breaker technology improved, circuit breaker manufacturers introduced a dual pressure design for 145kV through 800kV applications, as well as air-blast breakers utilizing SF6 as the line-to ground dielectric insulation.
