  • SF6 HANDLING – INSULATING GAS CALLS FOR LEAK

    Gas-insulated switchgears are filled with SF6, which has to be evacuated for maintenance. To prevent the gas from leaking, portable recovery systems are used, consisting of one or several vacuum pumps, a filter and a compressor. The SF6 is pumped from the switch gear to achieve a vacuum. The gas is then filtered and
