  • 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.

  • HOW TO MAINTAIN SF6 CIRCUIT BREAKER

    SF6 is a gaseous dielectric used in high voltage electrical equipment as an insulator or arc quenching medium. The separation of the CB contacts which are carrying current give rise to an arc. During arcing the circuit breaker maintains a relatively low pressure inside the chamber and there will be no danger of explosion and spilling of gas around.
