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 gaz sf6 gas in the load interrupting switch and switch-disconnector in SIMOSEC metal-enclosed load interrupter switchgear rated up to 27.6 kV.

However, currently even best practices are self-imposed and not widespread due to scant legal obligation on SF 6 emissions. Since switchgear typically has a lifetime of 40-50 years, it is critical to act now. Eaton, along with many other industry voices, is calling for an immediate ban of SF 6 gas in medium voltage switchgear up to 36kV.
