  • SF6 circuit breaker maintenance | TD Guardian Articles

    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.
