Embodiment of mechanical structure, its type of assembly might be: hinged, ground type, portable and built-in

Mechanical part

Low-voltage electrical switchboards are made of materials, which can accommodate mechanical loading, electric load and heat load, as well as humidity effect and intrusion of dust, which appear in normal operating conditions.

Corrosion protection of metal cases is provided by application of porcelain enamel to exposed surface; in such case conditions of usage and technical service should be taken into account. The fibers obtain sufficient mechanical strength and are able to sustain a load in normal operating conditions.

The configuration of equipment and stringers of low-voltage electrical switchboard provide easy and safe handling. .

The doors of low-voltage electrical switchboard have a locking arrangement.
