  • sf6 gas circuit breaker maintenance | TD Guardian Articles

    The first generation of Sulfr hexafluoride 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 sf6 gas as the line-to ground dielectric insulation.
