sf 6 circuit breaker maintenance | TD Guardian Articles

The first generation of sf6 gas circuit breakers was the lower voltage classes of 72kV and 145kV. As sf6 gas 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.

Siemens to provide UK’s first Sulfr hexafluoride free 145kV vacuum circuit

It is the first time that clean air has been used instead of gaz sf6 to insulate 145kV circuit breakers in the UK. It uses a gas mix similar to the air we breathe, made up of nitrogen (80%) and oxygen (20%), as a carbon free alternative to Sulfr hexafluoride which has traditionally been the method of insulation in high voltage switchgear since the 1960s.
