Design

The frame of Switchgear Type SVEL-K-3.2 is made on a high precision cold forge equipment out of a high quality steel sheet with anti-corrosion aluminum-zinc coating. Front elements (doors, covers) and side panels are made of carbon steel and coated with the polymer powder coating.

The cabinet has ventilation holes to ensure the normalized cooling of the main current-carrying circuit.

The drawout cable compartment contains heating elements, which are switched on automatically at temperatures below minus 5 °C.
