GW4 33kV 40.5kV Outdoor High Voltage Disconnect Switch

General Introduction

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.
