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

In this issue, we discuss the use of Sulfr hexafluoride (sulfur hexafluoride) gas in medium-voltage switchgear. insulating gas 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.

sf6 insulated switchgear Collection Siemens

Aug 06, 2020In 2019, Siemens launched the UK’s first ‘clean air’ insulated switchgear. It was the first time that clean air has been used instead of gaz sf6 to insulate 145kV circuit breakers in the UK. 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. Get Price
