SF6 Gas Storage Chongqing Gold Mechanical

Sulfur hexafluoride (SF 6) or sulphur hexafluoride (British spelling), is an extremely potent and persistent man-made greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom.[PDF]Handling and Use of Sulfur Hexafluoride Gas

SF6 is used in the SIMOSEC switchgear design for the load interrupting switch and for the switch-disconnector in a variety of configurations. This design takes advantage of the main characteristics of SF6 and minimizes the environmental issues associated with the gas. The switch is enclosed in a welded stainless-steel vessel of enclosure.[PDF]SF 6 Insulated Switching Solutions
