SF6 gasplant Distributor for high voltages

Air circuit breakers (ACB): ACBs can be used both as circuit breakers of low voltage electrical distribution systems and for protection of electrical equipment in facilities and industries.A common breaking principle is to use the magnetic field, created by the current through the ACB, to force the arc towards insulating lamella.

  • SF6 Gas servios for Substation - karina.net.pl

    Sulfur hexafluoride (SF6) gas-insulated circuit breakers are available for medium and high voltages, such as gas-insulated substations. When a current is interrupted, an arc is generated. This arc must be contained, cooled, and extinguished in a controlled way so that the gap between the contacts can again withstand the voltage in the
