  • Gas Circuit Breakers(GCB) : Transmission and Distribution

    With high voltage and high current distribution systems, a Gas Circuit Breaker (GCB) that uses SF6 gas, with three times the insulating ability of air, is applied. This technology releases a circuit of electrodes within compressed gas, extinguishes the generated arc by blowing a stream of supersonic air, and interrupts the current.

  • Leading the way in EFVs - hubbellcdn

    EFVs are similar to electrical circuit breakers that trip when electrical current exceeds design limits. They automatically trip when gas flow to a private residence or commercial facility exceeds design limits. This would be the case if a gas service line were to rupture because of ground movement, natural disasters or third party damage.
