A 300-ton transformer manufactured by WEG has been transported over approximately 800 km from Minas Gerais to São Paulo, where it will support a major transmission infrastructure project led by TAESA.

The delivery was carried out through a specialized heavy-haul logistics operation involving route planning, structural analysis of bridges and roads, and coordinated escorts due to the transformer’s size and weight. The equipment is intended for installation at the Assis Substation in São Paulo state.

The project includes three single-phase transformers rated at 500 MVA each, forming a combined 1.5 GVA transformation bank. WEG supplied the transformers, which are designed to operate in voltage conversion ranges between 440 kV and 525 kV, supporting high-capacity long-distance electricity transmission.

A key component of the project is its integration with Brazil’s first 525 kV underground transmission system, developed using high-voltage cable technology provided by Prysmian. The underground design reduces reliance on overhead lines and is intended to improve grid resilience, reduce environmental exposure, and limit surface infrastructure requirements.

TAESA is responsible for the transmission infrastructure development and integration of the system into Brazil’s National Interconnected System. The Assis Substation plays a strategic role in strengthening regional transmission capacity and supporting future expansion of high-voltage corridors.

The project highlights the collaboration between equipment manufacturing, transmission operators, and cable technology providers in advancing Brazil’s high-voltage energy infrastructure.
