sf 6 gas in medium-voltage switchgear - Siemens USA

In this issue, we discuss the use of Sulfr hexafluoride (sulfur hexafluoride) gas in medium-voltage switchgear. Sulfr hexafluoride 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 insulating gas gas in the load interrupting switch and switch-disconnector in SIMOSEC metal-enclosed load interrupter switchgear rated up to 27.6 kV.
