new type so2 Storage Systems for gas-insulated switchgears

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.

This is very important requirement and it requires relatively large clearancesand, in consequence, open-air substations tend to cover large ground areas. Also, if substation is located near local communities, they’re usually not very happy about its location. Some degree of landscaping is normally required to minimize the visual impact.
