  • Circuit Breaker - Working Principle, Types and Safety Tips

    The main feature of SF6CB is that they use sulfur hexafluoride gas (SF6) in their operation. This gas has an excellent insulating property that makes SF6CB very effective devices. Furthermore, SF6 has the property of rapidly recombining after extinguishing the arc, being a much more effective cooling medium than air.

  • Sulfur hexafluoride circuit breaker - Wikipedia

    Current interruption in a high-voltage circuit breaker is obtained by separating two contacts in a medium, such as sulfur hexafluoride (SF 6), having excellent dielectric and arc-quenching properties. After contact separation, current is carried through an arc and is interrupted when this arc is cooled by a gas blast of sufficient intensity.
