The research pointed out that SF6 is a remarkable medium for arc extinction. The arc extinguishing properties are improved by moderate rates of forced gas flow through the arc space. Plain break contacts drawn apart, (AC arcs), in SF6 can interrupt about 100 times more current than in air at given voltage.

SF6 can be prepared from the elements through exposure of S8 to F2. This was also the method used by the discoverers Henri Moissan and Paul Lebeau in 1901. Some other sulfur fluorides are cogenerated, but these are removed by heating the mixture to disproportionate any S2F10 (which is highly toxic) and then scrub…See more on en.wikipedia.orgChemical formula: SF₆Molar mass: 146.06 g/molMelting point: −64 &C; −83 &F; 209 KSolubility in water: 0.003% (25 &C)Top RF connector Manufacturers Suppliers in China RenhotecRF renhotecrfRF Connector Manufacturers and Supplier in China, supply high quality RF Coaxial Connector, adapter, cables with factory price.
