  • What is distribution substation and its main components

    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 circuit.
