  • Sulfur hexafluoride | F6S - PubChem

    Sulfur hexafluoride is a sulfur coordination entity consisting of six fluorine atoms attached to a central sulfur atom. It is the most potent greenhouse gas currently known, with a global warming potential of 23,900 times that of CO2 over a 100 year period (SF6 has an estimated lifetime in the atmosphere of between 800 and 3,000 years).

  • SF6 Gas or Sulfur Hexafluoride Gas Properties | Electrical4U

    Oct 22, 2020History of SF 6. SF 6 or sulfur hexafluoride gas molecules are combined by one sulfur and six fluorine atoms. This gas was first realized in the year 1900 in the laboratories of the Faculte de Pharmacie de, in Paris. In the year of 1937, General Electrical Company first realized that SF 6 gas could be used as gaseous insulating material. After the Second World War, i.e. in the middle of 20 th

  • SF6 Basic pressure question | Physics Forums

    May 04, 2017We use Industrial Gas cylinders filled with SF6 gas - the gas cylinder is 70-80% liquid and the rest is in a gaseous state. If this is kept at a pressure of approx 40Bar and is passed through a regulator that allows the gas to be filled into a containment unit at 1bar - How does the liquid SF6 become a gas when kept at the same temperature?

  • SF6 gas as insulating and arc-quenching medium

    Sep 20, 2011The isolating gas pressure is generally 350 to 450 kPa at 20 &C. In some cases this can be up to 600 kPa. The quenching gas pressure is 600 to 700 kPa. Outdoor apparatus exposed to arctic conditions contains a mixture of SF6 and N2, to prevent the gas from liquefying. The pressure-temperature relationship of pure SF6 gas is shown in Fig. 11-1.
