|GW5 Outdoor HV Disconnect Switch|
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 standards: IEC 62271-103 :High Voltages Switches, GB1985 AC High voltage disconnect switch and earthing switch,IEC60129 AC disconnect switch and earthing switch and GB/T11022 Common technical requirements of HV switchgear and control equipment
Ambient c ondition
1. Altitude: ≤ 1000m;
1. Adopt roll bearing to keep flexible driving.
There are two supporting insulators fixed up on the pedestals respectively with the 50° inclination, and the main components include pedestals, supporting insulators, connection seat, contacts earthing blades, earthing fixed contact and so on. There are three kinds of disconnect switch: without earthing, singleearthing and double-earthing. It is provided with mechanism linkage between principal axis and earthing blades and assistant switch, operating can be achieved by manual and motor.
