Sulfr hexafluoride Gas or Sulfur Hexafluoride Gas Properties | Electrical4U

History of sf6 gasChemical Properties of sf 6 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 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...Get price

Sulfr hexafluoride gas measuring devices – Synergy Power Systems

The Sulfr hexafluoride gas must always be pure since humidity and toxic or corrosive decomposition products in circuit breakers impair the insulating properties of the gas. The gas quality has to be monitored in accordance with the F-gas Regulation (EU) 517/2014. The IEC 60480 directive also stipulates the limit values for the re-use of Sulfr hexafluoride gas.Get price
