High voltage gas insulated switchgear: an overview - IET ...: In 1967 the first gas insulated metal-enclosed switchgear went into service in the German 110 kV network. Today GIS technology is successfully used for voltages up to 800 kV. GIS is an attractive alternative to conventional air insulated substations (AIS) because of the increased availability, reliability and the reduced life cycle costs.

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.
Gas-insulated switchgear - Hitachi ABB Power Grids high-voltage switchgear (GIS) is a compact metal encapsulated switchgear consisting of high-voltage components such as circuit-breakers and disconnectors, which can be safely operated in confined spaces. GIS is used where space is limited, for example, extensions, in city buildings, on roofs, on offshore platforms, industrial ...
Gas Insulated Switchgear Assembly (GIS) | Electrical ... insulated switchgear assemblies are gaining importance because of the innate advantage of compactness. Inert, non-flammable SF6 provides three times stronger insulation than air; hence using it as an insulation medium allows for drastic reduction of size and space for high voltage switchgear …

Sensgear: Born connected 2.0 | Transmission Products | Global imagine: Gas-insulated switchgear or circuit breakers, arresters, and instrument transformers let you know their current status in real time via an online application. If your substation is equipped with a Sensformer® on top, you get to know your grid a lot better.
Switchgear - Wikipedia for lower voltages may be entirely enclosed within a building. For higher voltages (over about 66 kV), switchgear is typically mounted outdoors and insulated by air, although this requires a large amount of space. Gas-insulated switchgear saves space compared with air-insulated equipment, although the equipment cost is higher.
