sulphur hexafluoride tools for Ultra High Voltage

Sulfur hexafluoride, sf6, is a gas used as an insulator in conjunction with solid insulating material in high voltage systems such as transmission lines, substations and switchgear. In the course of operating such high voltage systems electrical discharges can occur in the form of coronas, arcs or sparks.

  • Sulfur hexafluoride - Wikipedia

    Sulfur hexafluoride (SF 6) or sulphur hexafluoride (British spelling), is an extremely potent and persistent 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.Chemical formula: SF₆

  • Switchgear - Wikipedia

    Breakers that use carbon dioxide as the insulating and arc extinguishing medium work on the same principles as a sulfur hexafluoride (SF 6) breaker. Because SF 6 is a greenhouse gas more potent than CO 2 , by switching from SF 6 to CO 2 it is possible to reduce the greenhouse gas emissions by 10 tons during the product lifecycle.
