sf 6 Gas or Sulfur Hexafluoride Gas Properties | Electrical4U

History of insulating gasChemical Properties of gaz sf6 GasElectrical Properties of insulating gas GasSulfr hexafluoride 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 20th century, the popularity of using sulfur hexafluoride gas as an insulating material in electrical system was rising very r...
