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.
