CGW5 Outdoor Disconnecting switch
General Description
CGW5 outdoor disconnect switch is an outdoor H.V.Circuit electric applicance in AC 5OHz,rated voltage 40.5kV,72.5kV and 126kV.it can be used for H.V. Circuit making under no— load condition and electric— disconnecting in inspection of HV. Gereratrix,applicances as circuit breaker and live H.V. Wire.also,it can be used to make small capacitance or inductive current.
Type And Meanings
Main technical parameter
Structure Characteristics
Each unipolar equipment is firmed in a base with two post insulatorsshaping a V with intersection 50.the main structures as below:base ,post insulator,terminal base.contact.earthing switchearthing static contact And cable terminal.
This switch is sorted by earthing—free,single earthing and double earthi ng.there is a mechanical interlocking between main principal Axis and earthing switch.it is equipped with an auxiliary switch.it has manual and automatical operation ways.
Features
a.making current freely.turning flexibility due to rolling bearing,which leading to operational labor saving.
b.it is transmitted b bevel gear to make the two pillars making current consisitently.
c.the opening and closing brake has limited switch to ensure the contactors at the best position.meanwhile.the handie wiii be ouciea by lock ring after operation.
d.big clearance between open contacts.sufficient insulating and disconnecting fracture to ensure the operation safety.
e.it has earthing—free,single earthing and double earthing.there is a reliable mechanical inter locking between principal axis and earthing to ensure safety.users can choose the earthing way accordingly.
f.operation mechanism can be installed under either pole according to users.the operating effects are same.
