IMEFY´s transformers are manufactured according to IEC 76 standard. If you wish transformers accordind to another satnadards (ANSI, BSI, IEEE, NEMA, etc.), let us know.

IMEFY manufactures power transformers which the following characteristics.

- Rated power: From 2.5 MVA up to 60 MVA.
- Rated primary voltage: From 12 kV up to 132 kV.
- Rated secondary voltage: From 0.4 kV up to 132 kV.
- Frecuency: 50 Hz or 60 Hz.
- Tap changer: It is possible to realise no load no voltage with seven positions maximum. It is possible to realise on charge with seventeen positions maximum and automatic tap changer.
- Vector groups: On pimary and secondary windings it is possible to realise in delta or star position.
- Cooling: Transformers are manufactured with the following cooling type:
- Natural cooling (ONAN) or force cooling (ONAF). If you want OF cooling (oil pumping) please let us know.
- Type of tank: Transformers can be manufactured with the radiators welded to the tank, or with detachable radiators. Radiators can be finished with a conventional finishing or hot galvanized finishing. Final painting is realised with two epoxi imprimators caps and another epoxi final cap. The final treatment guaranties outdoor transformer instalation at the hardest environment. IMEFY normaliced finishing colour is the RAL 7033.
