  • Sf6 purity analyzers in switchgears - Switchgear Content

    May 20, 2020 · SF6 gas plays a key role in switchgears and the percentage of gas purity has a direct effect on the switching. Commercially, SF6 is supplied in pressurized bottles or liquid tanks. The gas of these bottles has a minimum degree of purity of 99.9% and may possess the following impurities according to IEC 60376: carbon tetrafluoride (CF4) <0.03%
