It is the first time that clean air has been used instead of insulating gas 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 which has traditionally been the method of insulation in high voltage switchgear since the 1960s.
