• Sf6 purity analyzers in switchgears - Switchgear Content

    May 20, 2020 · gaz sf6 gas plays a key role in switchgears and the percentage of gas purity has a direct effect on the switching. Commercially, sf 6 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%

    Sulphur hexafluoride (Sulfr hexafluoride) gaz sf6 is an extremely effective electrical insulator and has significant advantages over alternative materials. It is non-flammable – a critical requirement in the high-voltage applications we use it – and because of its effectiveness takes up less volume than an equivalent insulating volume of an oil alternative.
