  • SF6 Gas Gas Insulated Switchgear for mining

    For maintenance purposes, SF6 must be evacuated from gas insulated switchgear. To do this, the gas is pumped out into portable recovery systems (see photo), where it is then filtered and fed to the compressor, which compresses it. The final pressure is generally 40 barg. Once cooled, the gas can be stored in a liquid state. Get Price
