Sulfr hexafluoride Gas or Sulfur Hexafluoride Gas Properties | Electrical4U

History of insulating gasChemical 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 gaz sf6 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 rapidly. Allied Chemical Corporation and Pennsalt were the first American industries, who began to produce this gas commercially in 1948. During 1960, using of sulfur hexafluoride gas in high voltage switchgear became popular. As the demand for this gas was increasing, many manufacturers in Europe and America started producing sf6 gas gas in large scale, during that time. In the beginning, sf6 gas gas was only used for the insulating purpose in the electrical system. But soon it was realized that this ga...Get price
