1.GW-12/630-25 Outdoor AC H.V. Disconnect Switch (Disconnect Switch for short hereunder) are used in electric power system with rated frequency 50Hz, rated voltage 12kV. Disconnect Switch is mainly for making or breaking circuit under line supplying voltage in outdoor high voltage distribution system equipments. Thereof anti-pollution type Disconnect Switch can effectively solve the filth flash during operation so as to meet the requirements of users in heavily polluted area. And the switch that three-pole move in succession, can keep better synchronicity. The spring, can realize while allocating that open and shut fast.

4. Main Structure Illumination and Outline Dimension
Disconnect Switch is composed of base, pillar and operating insulator, fixed contact, contact blade and linkage spring mechanism, etc.
4.1 Base: Base is bended from steel sheet in 5mm thick,axis with pulling arm cross trough the base center. Holes drilled on base are used for fixing post insulator, installing earthing bolts and fix phases when installation, slot hole on crest setting for pulling arm.
4.2 Post and operating insulator: applying ZS-12 outdoor stick type post insulator, its anti-bending load is 4000N. Middle operating insulator up end linked with contacting blade and down end linked with pulling arm for pulling shaft.
4.3 Fixed contact: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.
4.4 Contact Blade: contact blade made of two rectangle section red copper plates, both ends of contact blade attached with spiral spring used for adjusting contacting pressure.
4.5 Switch could be linkage operated combined with CS mechanism horizontal mounting on outdoor power pole.
