Sulphur Hexafluoride Circuit Breaker. The sulfur hexafluoride circuit breaker uses SF6 gas for extinguishing the arc. The SF6 gas has great arc extinguishing property, and it is also superior as compared to other arc quenching media such as oil or air. Advantages Switching is very softer than, for example, vacuum breakers.

    of important advantages: High dielectric strength at lower cost When pressurized, sulphur hexafluoride can exhibit the same dielectric strength as liquid insulators. However, the per-unit-volume cost of SF 6 is only a fraction of that of liquid dielectrics. Regeneration capacity Following a breakdown, sulphur hexafluo-ride regenerates itself.
