WEgrid sf6 base separating unit

SF6 Circuit breaker; Main component used for this breaker is Sulphur Hexa fluoride gas in the quenching medium. When it is closed the contact will remain with the SF6 gas with the pressure of 2.8 kb/cm2. This is a kind of electro negative gas. As a result they will absorb more electrons. It results in high power and voltage services. They are cheaper.

When it comes to interrupting a high short-circuit break-ing current, the SF 6 gas is heated up considerably at the arcing contact due to the energy of the arc.
