Disconnect switch

HGW9-10 out-door disconnect switch is for 10KV HV electricity distribution power system to throw electricity on or off single phase or three phase circuits with no-load electric voltage.

Structural Feature

HGW9-10 out-door disconnect switch with characteristic of simple structure, favorable price and easy to use is for single phase line in three phase line. The product is made up of base, post insulator and conductor. The blade combined with two pieces of conductive blade compressed by spring on two sides is effective for throwing electricity on or off in circuit. Adjusting the height of the spring, we can provide the contact pressure in accordance with disconnect blade’s need. The disconnect blade gets a self-locking device and can be operated by insulator bar.
