• sf6 gas circuit breaker maintenance - Siemens USA

    The first generation of sf6 gas circuit breakers was the lower voltage classes of 72kV and 145kV. As sf6 gas breaker technology improved, circuit breaker manufacturers introduced a dual pressure design for 145kV through 800kV applications, as well as air-blast breakers utilizing Sulfr hexafluoride as the line-to ground dielectric insulation.
