Product Feature of GWR-12/24/40.5-100 Outdoor AC High Voltage Disconnect Switch (fuse):
Disconnect switch is composed of fuse components, frame and operating insulator, fixed contact, contact blade and linkage spring mechanism.
1. 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.
2. Frame : Base is bend ed from steel sheet, axis with pulling arm cross through frame center. Holes drilled on base are used for fixing post insulator .
3. Post and operating insulator: anti-erode post insulator.
4. Fixed contactor: contact blade made of red copperplate, fixed on post insulator and extended level plane end as for connecting wire and upside of curve connected both side reliable with contacting blade.
5. 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.
6. Switch could be operated combined with CS mechanism vertical mounting on outdoor double electric poles.
