Mounted Outdoor Switch Disconnector Pole mounted Isolating Switch Of High Voltage
Description of GW4 Disconnect Switch:
This type disconnector is a kind of HV outdoor electric equipments used in three-phase AC 50Hz electrical system . It is used for swithing-on/off the HV circuit when there is no load in the circuit in order to charge or transfer the circuit and also dissconnect the current with the bus bar , breaker or any other HV electrical equipments when overhauling the circuitry .
