Three-phase transformers are dimensioned for rated power from 50 to 8000 kVA and voltage of up to 36 kV. They are suitable for indoor and outdoor use.

Special transformers and medium voltage inductors have a long tradition in Končar D&ST and are known all over the world.

We produce medium power oil immersed transformers and special transformers up to 160 MVA with the maximum equipment voltage of 170 kV. They are intended for outdoor and indoor installation.

The transformers are dimensioned for rated power from 50 to 5000 kVA and voltage up to 24 kV. They are intended for indoor usage.
