sf 6 gas in medium-voltage switchgear - Siemens USA

The US EPA reports that gaz sf6 has an atmospheric lifetime of around 3200 years, and a global warming potential (100-year horizon) of 23,900 times that of CO2. The EPA does no t report emission of insulating gas separately, but instead reports a group of gases, including hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and gaz sf6.

gaz sf6 circuit breaker maintenance - Siemens USA

The first generation of sf 6 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 Sulfr hexafluoride as the line-to ground dielectric insulation.
