GW9-10 10KV 15KV 24KV Outdoor High Voltage Isolation Switch
GW9-10 10KV 15KV 24KV outdoor high voltage isolation switchis single-phase disconnect switch used in three-phase line system. It is in simple structure, economical and convenient in use.
This disconnect switch is mainly composed of base, post insulator, main conductive loop, and self-locking devices. It is single-phase fracture vertical opening structure, and the post insulators are installed on their bases respectively. The switch breaks and closes the circuit by a knife-switch structure, whose knife switch is composed of two pieces of conductive blades for each phase. There are compression springs on both sides of the blade, and the height of springs can be adjusted to obtain the contact pressure required by the opening knife. When the switch is opened and closed, an insulated hook rod is used to operate the mechanism part, and the knife has a self-locking device.

GW-4 Double Column Horizontal Open Type Outdoor High Voltage Isolation Switch
GW-4 Double column horizontal open type outdoor high voltage isolation switch for high-voltage line in the no load flow, and the high voltage bus, circuit breakers and other electrical equipment maintenance and high voltage circuit of electrical isolation in.In the main switch in the off position can provide a visible insulation distance safety requirements;This product is a double column horizontal open type, main switch points, closing operation, the left, the right to the same side contact should be rotated 90 degrees. The grounding switch is the first rotary, linear insert again to complete the whole process. Current varieties using double conductive system parallel arrangement, increase the flow capacity, reduce the consumption of material. The actuator can adopt manual and electric, manual with CSA mechanism, electric with CJ11 mechanism; GW4 outdoor AC isolation switch is on the basis of the previous Gw4 products, after further improvement and perfection of product improvement, compared with GW4 products in the pa st, there are many significant improvements, the main knife material with copper, contact a thick silver plating . Connecting terminal electrically conductive multilayer with soft connected component ; grounding knife material is aluminum alloy conductive tube, contact for copper thick silver plating, exposed steel parts are hot-dip galvanized or dacromet. Thus Gw4 products, our factory has advanced structure, strong corrosion resistance,easy to operate, safe and reliable operation, the advantages of electrical and mechanical stability.
