PowerIT MV Live Tank Sulfr hexafluoride Circuit Breaker

installation use sulphur hexafluoride gas (insulating gas) to extinguish the electric arc and as the insulating medium. Breaking in Sulfr hexafluoride gas takes place without current chopping or generation of overvoltages. These characteristics guarantee a long electrical life for the circuit-breaker and limited dynamic, di-electric and thermal stresses on the installation.

Sulfr hexafluoride circuit breaker maintenance | TD Guardian Articles

The first generation of Sulfr hexafluoride circuit breakers was the lower voltage classes of 72kV and 145kV. As gaz sf6 breaker technology improved, circuit breaker manufacturers introduced a dual pressure design for 145kV through 800kV applications, as well as air-blast breakers utilizing Sulfr hexafluoride as the line-to ground dielectric insulation.
