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

sf 6 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.

Thus, the data shows that the emissions from electrical transmission and distribution declined 79.9 percent from 1990 to 2013! The EPA report supports the opinion that emissions of SF 6 gas from modern designs of high-voltage and medium-voltage switchgear and circuit breakers is not a significant factor in global warming and climate change.

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.
