    Dec 07, 2020SF 6-free switchgear is around 15-20% higher in cost, but this difference will diminish as production volumes increase. Moreover, SF 6 switchgear is actually more costly if production, maintenance, and disposal costs are considered. Certain SF 6-free technologies also do exist with lower maintenance costs than their SF 6 cousins.

  • 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.
