SF6 gas Mixtures Electrical substation training

SF6 gas Mixtures Electrical substation training

Equipment manufacturers have been conducting research for years to find a more environmentally friendly, but equally effective substitute for SF6 use in high and medium voltage switchgear. A gas mixture prepared using a product called Novec 5110 dielectric fluid appears to meet all the required characteristics that make SF6 so attractive.

  • SF6 Gas Use in Electrical Applications - SF6

    Sep 03, 2018Sulphur hexafluoride (SF 6) is a man-made gas comprising of one sulphur and six fluoride atoms. SF 6 gas is extremely chemically stable, non-flammable and highly electronegative, with an excellent dielectric property of approximately 2.5 times more than air. Therefore, it is commonly used in electrical switchgear, transformers and substations as an electrical insulation, arc quenching and

Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse-effect, if it is released into the atmosphere. However in electrical switchgear the SF6 gas is always used in gas-tight compartments, greatly minimising leakage.
