Overview
Description:

(H) GW8 neutral point isolating switch is a single-pole direct-gravity three-phase AC 50Hz outdoor high-voltage electric appliance, which can be used for splitting the neutral point of the transformer in the case of no load. When the knife is in the normal opening position Provide an insulation distance that meets safety requirements.

structure:

The product is a single-pole single-column snap-on structure with a small footprint; it is mainly composed of a base, a post insulator, a conductive loop, and an operating mechanism. The guillotine is mounted on the lower portion of the post insulator, and the stationary contact is mounted on the upper portion of the post insulator.

A vertical insulation gap is formed between the blade at the time of opening and the static step directly above. When the action is combined, the knife rotates in a vertical plane until it hits the static contact and engages correctly.

The neutral point isolating switch can be equipped with CS8, CS17IV perfecting and improving human body mechanism, and can also be equipped with CJ6G perfecting and improving electric motor mechanism. The human body mechanism can also be equipped with the new DSW4 electromagnetic lock.
