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: GB1985 AC High voltage disconnect switch and earthing switch, IEC60129 AC disconnect switch and earthing switch and GB/T11022 Common technical requi rements of HV switchgear and control equipment.
There are two supporting insulators fixuped on the pedestals respectively with the 50 inclinat ion, 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, single-earthing and double-earthing. It be provided with mechanism linkage between principal axis and earthing blades and assistant switch, operating can be achieved by manual and motor.
