Switchgear - Wikipedia 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.
Siemens Tender specifications specified switchgear is a factory-assembled, type-tested, 3-pole metal-enclosed, gas-insulated medium-voltage switchgear according to IEC 62271-200. The following panel types must be available: Circuit-breaker panel with vacuum circuit-breaker; Switch-disconnector panel as ring-main panel
