GW5 outdoor high voltage disconnect switch is used to make or break high voltage circuit in rated voltage 40.5kV, 72.5kV or 126/145kV, AC 50/60HZ system. It is also used to open and close small capacitance and inductive current. This series disconnect switch accord with standard: GB1985 AC HV disconnect switch and earthing switch, IEC60129 AC disconnect switch and GB/T11022 common technical requirements of HV switchgear and control equipment.
1.Adopt roll bearing to keep flexible friving.
2.Adopt umbrella-gear wheel mechanism to ensure O/C operating congruously.
3.An direction-limited device to ensure the contactor under good direction.
4.Contact distance is large enough.
5.Three type earth method, without earth, single earth, double earth.
