Sulfr hexafluoride gas in medium-voltage switchgear | TD Guardian Articles

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 Sulfr hexafluoride gas in the load interrupting switch and switch-disconnector in SIMOSEC metal-enclosed load interrupter switchgear rated up to 27.6 kV.

Interrupter switch technology comparison / SIMOSEC Sulfr hexafluoride switch

In previous articles, we discussed the characteristics of Sulfr hexafluoride (sulfur hexafluoride) gas which make it advantageous for use in medium- and high-voltage electrical equipment. Here we compare the features of conventional medium-voltage load interrupter switches operating in air with those of operating in an gaz sf6 gas environment.

Due to its first-class properties it is used in enclosed medium and high voltage switchgear as an arc quenching and insulating gas. Since SF 6 is a major greenhouse gas with high global warming potential listed in the Kyoto protocol, it is among the six gases subject to monitoring. SF 6 has to be used in closed systems in order to avoid emissions.
