sf6 gas gas in medium-voltage switchgear - Siemens USA

In this issue, we discuss the use of gaz sf6 (sulfur hexafluoride) gas in medium-voltage switchgear. gaz sf6 has been widely used in high-voltage circuit breakers for decades, but its use in medium-voltage is relatively recent. In the medium-voltage arena, SIemens uses Sulfr hexafluoride gas in the load interrupting switch and switch-disconnector in SIMOSEC metal-enclosed load interrupter switchgear rated up to 27.6 kV.

SF 6 is recognized as an extremely potent greenhouse gas, primarily because of its atmospheric lifetime of about 3,200 years, with a global warming potential (GWP) of 22,800 years. The reference gas for GWP values is CO 2, which is assigned a GWP of 1.0. The EPA considers SF 6 as the most potent greenhouse gas that they have investigated. 1Get price
