High-voltage Disconnector Switch

Overall and Installation Dimension

GW4 TypeOutdoor High-Voltage Isolating Switch Series

Main application

GW4 type outdoor high-voltage isolating switch is used for three-phase AC 50Hz

outdoor high voltage electrical equipment, used for the line to switching under

pressed voltage no load condition, and electrical isolation the maintenanced high

voltage bus, circuit breakers and other electrical equipment and charged high

voltage line, can also be used for the opening and closing small capacitance or

inductance current. When the knife in the normal break position, can provide a

insulation distance consistent with safety requirements. Widely used in 35~110kV

substation.
