Схема подключения

A cubicle switchboard of T-01 series with solid insulation

Description

A precast-welded body of a cell is made from powder-coated steel on the facia, its side and rear walls are made of galvanized steel, a pallet, an instrument cabinet. Bearing elements of the body are assembled with the use of steel embedded studs.

All current carrying elements and contact connections in the cell are insulated. Vacuum chambers, stationary and movable contacts of a disconnecting switch are in the case made of solid polyamide (polycarbonate) insulation material, each phase is in a separate case. Movable and stationary contacts of a grounding conductor are also in the special insulated glasses installed on the cases of phases.
