Indoor & outdoor substations, an overview· Gas-insulated substations: Gas insulated switchgear (GIS) incorporates all of the same functional elements as air insulated switchgear, but condenses them inside a sealed housing that occupies one tenth of the space. GIS is ideal for use in harsh environments, such as corrosive, salty air or extreme temperatures.
Siemens supplies green 66kV switchgear for UK wind farm· Siemens will supply 102 high voltage gas insulated switchgear (GIS) for a UK wind farm in a multi-million euro deal. The switches operate with a vacuum circuit-breaker and clean air instead of polluting sulfur hexafluoride (SF6) as the insulating medium.
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.
