From design to commissioning

Five stages, one continuous line.

Every board completes the full quality-control route before it leaves the factory.

1
Engineering design

Load calculations, single-line drawings, take-off and shop drawings in the technical office.
2
Enclosure fabrication

Cutting and bending galvanized sheet, welding, and electrostatic powder coating.
3
Assembly and wiring

Equipment mounting, busbar work and control-circuit wiring.
4
Test and inspection

Current injection, megger, hi-pot and high-voltage testing.
TYPE TEST · نیرو
5
Installation and commissioning

Transport, site installation, final testing and handover.
