  • SF6 gas in medium-voltage switchgear - Siemens USA

    SF6 is used in the SIMOSEC switchgear design for the load interrupting switch and for the switch-disconnector in a variety of configurations. This design takes advantage of the main characteristics of SF6 and minimizes the environmental issues associated with the gas. The switch is enclosed in a welded stainless-steel vessel

  • You may have heard of decarbonisation, but have -

    In 2019, Siemens launched the UK’s first ‘clean air’ insulated switchgear. It was the first time that clean air has been used instead of 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 SF6.
