GW25 Outdoor High Voltage Disonnect 
Switch For Substation

General
GW25 outdoor high voltage disonnector switch has a double-column , horizontal , central, interruption structure,It is an equipment used for 50/60Hz three phase AC ,outdoor high voltage transmission and distribution system to switch and disconnect the circuit.
For this type disonnector switch, part of terminal is in contractless condition with the flexible conductor ,leading to a stable and reliable electricity performance.And the contact part adapt a safe and flxed device,so that contact and finger will not be separated by external force(like Strong Wind, Earthquake, Electric Power,etc.) when the disonnector switch in the close statement.
The base part adapt a multi-bearing structure to make the switch can operate flexibly in a long-term. Meanwhile, interphase drag rod and vertical link rod can adjust within ±20mm when in site installation. Because vertical link rod rotates 190°when disconnector is operated by operating mechanism, and then it constitutes a 5°dead-point structure at the open and close critical position ,so that make the switch cannot open and close automatically even under the external force.
Disconnector body can be equipped with grounding switch,which contain a mechanism can rotates 90°around its own long axis,so that the switch can operate flexibly.
When grounding switch close, it cannot happen contact separation even under the external force, also can bear the dynamic, thermally stable current same with the disconnecting switch.
Grounding switch and disconnecting switch with reliable mechanical interlock device,
Grounding switch also can like disconnecting switch to operate by the operating mechanism, otherwise,manual mechanism and motor mechanism can interchange.

GWR-12/36 Outdoor AC High Voltage Disconnect Switch (Fuse Type)

Summary

GWR-12/36 outdoor AC. high voltage fused type disconnect switch (disconnect switch for short) is used in electric power system with rated frequency 50/60Hz, rated voltage 12/36kV. Its main for making or breaking circuit under line supplying voltage in outdoor high voltage distribution system equipments. Thereof anti-pollution type disconnect switch is especially used in serious polluted area. It accords with standards of IEC62271-103: High voltage switches.

Ambient Condition

Altitude: ≤1000m;
Ambient temperature: +50℃ ~-30℃;
Wind speed: ≤35m/s;
Earthquake intensity: ≤8 degree;
Air pollution: IV;
Ice thickness: ≤10mm;
Applicable occasions of normal type switch should free from chemistry aggradation, dust and other volatile & caustic thing.

Model

Structure Feature

Disconnect switch is composed of fuse components, frame and operating insulator, fixed contact, contact blade and linkage spring mechanism.

Cutout fuse assemble: mainly combine with upper, down movable and fixed contact, arc extinguish bushing, insulator and mount support parts, during normal work, the fuse linking the moving joint of the arc extinguish bushing with movable contactor, the arc extinguish bushing is at closed position under the pressure of the fixed contactor.
Frame: Base is bended from steel sheet, axis with pulling arm cross through frame center. Holes drilled on base are used for fixing post insulator.
Post and operating insulator: anti-erode post insulator.
Fixed contactor: contact blade made of red copper plate, fixed on post insulator and extended level plane end as for connecting wire and upside of curve connected both side reliable with contacting blade.
Contact blade: it's made of two rectangle section red copper plates, both ends of contact blade attached with spiral spring to adjust contacting pressure.
Switch could be operated combined with CS mechanism vertical mounting on outdoor double electric poles.
