gaz sf6 gas in medium-voltage switchgear | TD Guardian Articles

In this issue, we discuss the use of insulating gas (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 sf 6 gas in the load interrupting switch and switch-disconnector in SIMOSEC metal-enclosed load interrupter switchgear rated up to 27.6 kV.
