  • SF6 Circuit Breaker Types, Working Principles Maintenance.

    Feb 20, 2021 · Separation of the movable contacts is via an opening valve that allows a high pressure flow of SF6 gas at 14 kg/cm 2 to strike the arc and extinguish them. Since SF6 gas is electronegative and has a powerful love for free electrons, it absorbs the conducting free electrons in the arc to form immobile negative ions.
