Transformer installation and medium-voltage pole removal

Modernizing an industrial facility involves more than purchasing new equipment. A successful electrical upgrade must also address transportation, access, positioning, connection and integration with the existing infrastructure.

For this Coca-Cola FEMSA project, STAR completed the installation of an industrial transformer and the controlled removal of poles associated with the medium-voltage network. The intervention brought together electrical work, heavy-equipment lifting, equipment movement and work at height within a single coordinated operation.

One of the main challenges was moving the transformer from the exterior of the facility to its final location inside the electrical room. Because of the equipment's size and the available access conditions, a dedicated maneuver was developed using a crane, slings and tag lines. The crew controlled each movement to maintain load stability and guide the transformer through the opening prepared in the building.

Once inside the facility, the transformer was progressively moved toward the installation area. This stage required constant coordination between the personnel controlling the suspended load and the crew guiding the equipment from inside, preventing contact with the structure and maintaining control throughout the transfer.

After the transformer reached its final position, the electrical work required for its integration into the plant was completed. The scope included conductor preparation, terminal installation and power connections, with an organized layout compatible with the existing switchboards, feeders and cable-management systems.

In parallel, STAR removed poles and components from the overhead medium-voltage infrastructure. These activities were carried out using a crane and aerial access equipment, allowing the structures to be dismantled progressively while keeping elevated components under control.

The project required the coordination of indoor electrical work with outdoor lifting operations, the management of heavy suspended loads and the execution of tasks near energized infrastructure. The result was a comprehensive upgrade that installed the new transformer, reorganized the electrical supply and cleared the areas previously occupied by the former medium-voltage poles.
