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

    It is 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 sf 6 which has traditionally been the method of insulation in high voltage switchgear since the 1960s.
