Minel Trafo – Production of transformers

Minel Trafo was founded on May 17, 1958. In its first year, 267 transformers were produced.


By continuously keeping up with technological advancements in the field of distribution transformer production worldwide, the factory entered the international market and has significantly increased its production year by year.

Through modernization of the production process, improvements in product design, and the use of high-quality materials, Minel Trafo has achieved the production of high-performance transformers characterized by low loss levels and low noise, in accordance with the European Union’s Eco Design recommendations.

The factory reached its production peak in 1980, when it manufactured around 6,000 transformers. Having gone through all stages of the development life cycle and various forms of privatization, with over 159,000 transformers produced, the factory remains competitive in the market today alongside all European manufacturers of oil-immersed distribution transformers, with a tradition of exporting to over 55 countries worldwide.

The company’s core activity is the design and production of oil-immersed distribution transformers with voltages up to 36 kV and rated power up to 4000 kVA.

In addition, the production range includes special types of transformers: regulating transformers, grounding transformers, converter transformers, autotransformers, dry-type transformers, all types of reactors, and transformers with a Peterson coil. Minel Trafo holds a license for the production technology of a special type of transformer with a wound core—Shingle Core Trafo®.

The production of all transformer electrical assemblies is carried out within the company itself. The manufacturing of magnetic cores (longitudinal slitting and step-lap cross-cutting of transformer steel) is performed on GEORG brand machines. The high- and low-voltage windings are produced on STOLLBERG machines. Drying and vacuuming of transformers are conducted in three drying ovens with a total volume of 140 m³.

In addition to well-developed in-process control procedures, the company also operates a laboratory where final testing of transformers is performed. For the past twenty years, Minel Trafo has operated under a quality management system in accordance with ISO 9001. The factory also holds environmental protection system certification ISO 14001, as well as occupational health and safety management certification.
