  • 220kV Gas Insulated Circuit Breaker(SF6)CB

    Modern SF6 type circuit breakers use compressed gas to interrupt current flow and are common in electrical power substations. Current interruption in a high-voltage circuit-breaker is obtained by separating two contacts in a medium, such as sulfur hexafluoride (SF6), having excellent dielectric and arc-quenching properties.
