CONSTRUCTION:

According to the structure, the dividers are of a vertical-rubbing type and have a three-pole design on a common frame.

They consist of a cap (frame), support insulators, a contact system, a traction insulator and earthworms. A drive shaft with levers is arranged on the disconnect frame and is intended for operation by means of contact knives.

If there are earthworms in the base, one or two shafts are additionally installed to control them, as well as a mechanical lock preventing the use of earthworms when the main knives are switched on and vice versa.

The insulation of the disconnector consists of six support and three traction porcelain insulators.

The disconnector contact system consists of fixed contacts and movable contact knives.

The ground-layers consist of a copper tyre attached to steel posts welded to the ground shaft.

When the ground setter is activated, the tyre enters the lampreys mounted on the lower shelves of fixed contacts.

The contact pressure in the axial and detachable contacts of the main knives and laminated contacts of the seizers is carried out by springs.
