SF6 Circuit Breaker

October 21, 2016 By admin No comments yet Switchgear

FeaturesSpecification
  • Even in the event of a complete gas leak, our SF6 CBs are capable of breaking 100% normal current & with stand system voltage
  • Advance warning of gas leak by continuous pressure monitoring
  • Explosion proof and fail-safe CB by means of safety membrane for each pole
  • Automatic safety shutters to cover live parts when CB is withdrawn
  • No degradation of main current carrying contacts, as there are separate currents carrying and arcing contacts
  • Our SF6 CBs operate at low pressure. The internal pressure rise at the instant of current interruption also stays low. Due to this, and the high degree of gas tightness, adequate for entire life of the breaker is ensured.
