History of SF6Chemical Properties of SF6 GasElectrical Properties of SF6 GasFor examine chemical properties of SF6 gas, we first introduce structure of SF6 molecule. In this gas molecule, one sulphur atom is surrounded by six fluorine atoms.The sulfur has atomic number of 16. Electronic configuration of sulphur atom is 2, 8, 6 i.e. 1S2 2S2 2P6 3S2 3P4. The fluorine atom has atomic number 9. The electronic configuration of fluorine is 1S2 2S2 2P5. Each sulphur atom in SF6 molecule creates a covalent bond with 6 fluorine atoms. In this way, sulfur atom gets total 6 cov...See more on electrical4u.comIs the end coming for sulfur hexafluoride, the most ... 15, 2020Current EU F-gas regulation prohibits the use of SF 6 in many non-electric applications, but not in MV switchgear. Today, about two thirds of the 15 million MV switchgear units installed in Europe (EU28) use SF 6. When the EU F-gas regulation was last revised in 2014, it was considered that no cost-effective and reliable alternatives to SF 6 were available.
