Koncar – Energetski transformatori d.o.o.

In 1966, the production of power transformers began in a newly built factory in the industrial zone of the western part of Zagreb, Jankomir. This made it possible to produce power transformers with ratings up to 400 MVA and voltages up to 550 kV for the domestic and foreign markets. With the factory extension in 1983, the capability was gained to produce three-phase power transformers up to 1000 MVA and 550 kV.

The largest transformers produced so far are: three-phase generator transformers of 725 MVA, 420 kV delivered in 1985, and a three-phase autotransformer of 1000 MVA, 420 kV delivered in 2016.
