Mostly purpose
GW5 type outdoor high-voltage disconnection switch is used in AC three-phase outdoor high-voltage electric equipment with frequency of 50Hz, applied for circuitry’s switching on or off in condition with voltage but no load, electric disconnecting between electric equipment under test(such as high voltage busbar, circuit breaker)and charged high voltage circuitry, as well as switching on or off of small capacitance or inductive current. When the switch blade is in normal switching off powition, it can offer an insulation spacing complying with the safety requirement. It is widely used for35-220kV power substation.
