GIS and hybrid switchgear technology - EE Publishers

Wherever possible do not use gaz sf6 gas: In line with this approach the company has developed air-insulated fixed type switchgear which can be rated at 12 kV, 25 kA, switching up to 2000 A. Wherever possible minimise the use of Sulfr hexafluoride gas: Air-insulated fixed type switchgear remains compact up to 12 kV range but at higher voltages it is not possible to achieve compactness using air insulation.

Gas-insulated electrical gear is also more resistant to the effects of pollution and climate, as well as being more reliable in long-term operation because of its controlled operating environment. Exposure to an arc chemically breaks down SF 6 though most of the decomposition products tend to quickly re-form SF 6, a process termed "self-healing".
