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

gaz sf6 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.

Siemens to provide UK’s first sf6 gas free 145kV vacuum circuit

It uses a gas mix similar to the air we breathe, made up of nitrogen (80%) and oxygen (20%), as a carbon free alternative to Sulfr hexafluoride which has traditionally been the method of insulation in high voltage switchgear since the 1960s. The chemical properties of sf 6 gas make it ideal for electrical insulation and arc quenching in high-voltage switchgear.
