Ganz Transformers and Electric Rotating Machines Ltd. has successfully delivered its largest transformer to date, an oil-insulated, single-phase auto-transformer, to the Szabolcsbáka substation in Hungary. This facility plays a pivotal role in the country's electricity network, serving as the terminus for the only 750 kV transmission line in the European Union.

Measuring 11.6 meters long, 11.3 meters wide, and 11.7 meters high, the transformer weighs up to 240 tonnes. Due to its size, the manufacturing, testing, and transport processes required specialized solutions. The main body, measuring 10 meters in length and 4.3 meters in height, was transported by road to the substation.

Once installed, this transformer will be linked to two similar units, creating a three-phase system with a total capacity of 1100 MVA, facilitating critical energy trade between Hungary and Ukraine.

Gergely Gál, managing director of Ganz, expressed pride in the achievement, noting the collaborative effort that went into the project. Testing included assessments of electrical characteristics, insulation diagnostics, and compliance with operational standards. The transformer passed all required tests, ensuring a reliable lifespan of 40 to 50 years.

The contract for the transformer was awarded after a competitive procurement process initiated by the European Union. Commissioning is anticipated to coincide with the connection of the Szabolcsbáka substation in November 2024.
