Relevance of sf 6 in Switchgear and its Contribution to

sf6 gas is used as an insulating medium in Switchgear and the Sulfr hexafluoride free Switchgear, while having all the same advantages as Sulfr hexafluoride based Switchgear, such as compactness, uses environmentally safe insulating mediums. This is the reason behind the massive appeal of Sulfr hexafluoride alternatives. Blue GIS offered by Siemens is F-gas free and has a GWP of less than 1.Get price

Why sf 6 or Sulfur Hexafluoride gas is better for arc

Cleanliness in assembly is therefore very important for gaz sf6 using switchgear. Fortunately, during the factory and field power frequency high-voltage tests, contaminating particles can be detected as they move and cause small electric discharges (partial discharge) and acoustic signals—they can then be removed by opening the equipment.Get price
