    The switch enclosure is filled with SF 6 (sulfur hexafluoride) gas, which allows for an extremely compact switch, and leads to exceptionally long switching life for the switch. Since the switch enclosure is hermetically sealed, there is no need to replenish the SF 6 gas over the life of the equipment.

  • Switchgear - Wikipedia

    A switchgear may be a simple open-air isolator switch or it may be insulated by some other substance. An effective although more costly form of switchgear is the gas-insulated switchgear (GIS), where the conductors and contacts are insulated by pressurized sulfur hexafluoride gas (SF 6). Other common types are oil or vacuum insulated switchgear.
