Power transformers are employed wherever it is necessary to connect transmission, distribution, and utilization systems operating at different voltages, enabling the transfer of large amounts of active and reactive power between these systems.

Our production range includes HV/MV transformers and MV/MV transformers for both energy and industrial applications, with a production range up to 150 MVA and an insulation class of 245 kV, meeting the needs of various industries – from the energy sector (including renewable energy production) to manufacturing.

By the side of the industry, with solutions for the steel sector

Electric arc furnace transformers are designed to serve the steel industry, powering both steel production furnaces and those for special alloys. These machines must handle high and variable power levels due to frequent short circuits, while withstanding intense electrical, thermal, and mechanical stresses.

To meet the challenges of industrial and steelmaking processes, BSTransfo designs and manufactures single-phase and three-phase transformers up to 100 MVA for arc furnaces (EAF), refining ladle furnaces (RLF), submerged arc furnaces (SAF), and electro slag remelting (ESR), for the steel and ferroalloy markets.
