Siemens to provide UK’s first insulating 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 Sulfr hexafluoride gas make it ideal for electrical insulation and arc quenching in high-voltage switchgear.
