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.

2012-2-1Common terms/definitions: Dewpoint: The temperature (in Degrees &C or &F) at which moisture (water vapor) in the gas begins to condense as liquid (droplets or dew) or solid (ice). Typical dewpoint in SF6 equipment ranges from -60C to -5C.
