sf6 gas Gas or Sulfur Hexafluoride Gas Properties | Electrical4U

History of insulating gasChemical Properties of gaz sf6 GasElectrical Properties of sf6 gas Gasinsulating gas 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 Sulfr hexafluoride 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...

Sulfr hexafluoride - Sulfur Hexafluoride Structure, Molecular Mass

Sulfur hexafluoride is a weaker eluent than carbon dioxide and difficult to obtain in adequate purity. It provides high dielectric strength and excellent arc-quenching properties. the high heat absorbing ability makes sulfur hexafluoride a strong greenhouse gas with a CO 2 equivalent contribution to the global warming potential.

May 01, 2000 · Abstract. We present new vapor phase speed-of-sound data u (P,T), new Burnett density-pressure-temperature data ρ (P,T), and a few vapor pressure measurements for sulfur hexafluoride (SF 6 ). The speed-of-sound data spanned the temperature range 230 K {less than or equal to} T {less than or equal to} 460 K and reached maximum pressures that were the lesser of 1.5 MPa or 80% of the vapor pressure of SF 6.
