  • SF6 circuit breaker maintenance - Siemens USA

    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.

  • SF6 gas as insulating and arc-quenching medium

    Sep 20, 2011Arcing causes the decomposition of very small amounts of SF6 gas. The decomposition products react with water, therefore the gas’s moisture content, particularly in the circuit-breaker, is controlled by drying (molecular) filters. Careful evacuation before first gas filling greatly reduces the initial moisture content.
