  • sf6 Gas Mixture unit for High Speed Rail

    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 which has traditionally been the method of insulation in high voltage switchgear since the 1960s. The chemical properties of SF6 gas make it ideal for electrical insulation and arc quenching in high-voltage switchgear.
