insulating gas Gas or Sulfur Hexafluoride Gas Properties | Electrical4U

History of gaz sf6Chemical Properties of sf6 gas GasElectrical Properties of Sulfr hexafluoride Gassf 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 insulating gas 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...Get price
