Cast Resin Transformer

These YG and LV windings are completely covered with vacuum cast epoxy resin under vacuum.

Power range 25 – 2500 kVA, high voltage level up to 36 kV, natural cooling (AN) or fan cooled (AF). (Up to 50% power increase with the used cooling fan)


  • Protect against these difficult situations. Therefore end-transformers are used in damp and dirty areas. Since the production of coatings, moististure and air bubbles can be prevented.
  • Dry type trailers are smaller in size than oily ones. It occupies less space than oil-filled transformers.
  • Dry type transformers provide a longer life at low temperatures and protect against the effects of diagenetic aging compared to the oil traffial.
  • The resistance of these trailers against high pressures is quite high.
  • Maintenance is not required.
