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 insulating gas. Get Price
