Sulfr hexafluoride circuit breaker maintenance | TD Guardian Articles

The first generation of Sulfr hexafluoride circuit breakers was the lower voltage classes of 72kV and 145kV. As sf 6 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.
