gaz sf6 circuit breaker maintenance | TD Guardian Articles

The first generation of Sulfr hexafluoride circuit breakers was the lower voltage classes of 72kV and 145kV. As Sulfr hexafluoride breaker technology improved, circuit breaker manufacturers introduced a dual pressure design for 145kV through 800kV applications, as well as air-blast breakers utilizing insulating gas as the line-to ground dielectric insulation.

Gas insulated power transformers: A growing technology - EE

Gas insulated transformers (GITs) have been in use since the 1960s, but use has been restricted due to higher costs and other reasons. Gas is used as an insulating and cooling agent in gas insulated transformers. Sulphur hexafluoride (SF 6) is the main gas used in these types of transformer at present although other gases are under development. The main advantage of gas insulated transformers is that they are environmentally friendly and can be recycled easily.
