Sulfur hexafluoride - Wikipedia hexafluoride (SF 6) or sulphur hexafluoride (British spelling), is an extremely potent and persistent man-made greenhouse gas that is primarily utilized as an excellent 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.Chemical formula: SF₆
NEC High Voltage Gas Insulated Switchgear Design ... High Voltage Gas Insulated Switchgear. The assembly shall be of dead tank type, with all components of the switchgear, for example circuit breaker, bus bars, disconnect switches, grounding switches, and instrument transformers, housed in grounded metal enclosures.
