sf 6 circuit breaker maintenance | TD Guardian Articles

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