GW5 high voltage isolation switch is an outdoor high voltage electrical equipment with AC 50Hz. Rated voltage levels are 40.5KV, 72.5KV and 126KV. It is used for electrical isolation of high voltage lines, and can also be used for opening and closing small capacitors or inductive currents.
Environmental conditions for use:
1. Altitude: no more than 3000 meters.
Ambient air temperature: upper limit is 40°C, lower limit is -25°C.
Wind speed should not exceed 35m/s.
The intensity of the earthquake does not exceed 8 degrees.
5. The pollution level shall not exceed Class II.
6. The ice thickness should not exceed 10 mm.
The installation site should be free of explosives, explosion hazards, chemical corrosion and violent vibration.
Features:
Isolation switch adopts double column happy turning contact structure, with contact self-cleaning ability, improve contact reliability; Contact refers to the use of high strength, high conductivity, high elasticity of new materials. Clamping contact by the elastic force of the contact finger itself avoids the vicious cycle of decreasing contact clamping force, increasing contact resistance, increasing contact resistance and intensifying contact heat caused by spring corrosion and thermal annealing at present; Isolation switch rotations are designed to be maintenance-free. The rotating seat is designed as a sealed structure, so that water vapor, dust and harmful gases can not enter, so that the bearing and lithium molybdenum disulphide grease always work in a good environment, the bearing never rust, the grease never loses, never dry. The operating torque of the isolation switch does not increase after prolonged operation. Stainless steel gold crank pin and oil-free self-lubricating bearing combination; The steel parts are hot-dip galvanized to ensure that the isolation switch is flexible, lightweight, reliable, and rust free.
