AC Line Feeder Non-​​Autotransformer

AC traction feeder transformers are used between normal three-phase AC networks and single-phase catenary systems. They are often equipped with an on-load tap-changer (OLTC). Their strong structure is specially designed to resist repeated short circuits during the operation, which are common in electric railways.

Product scope:

  • High voltage up to 400 kV
  • Power ratings: usually 7.5 - 25 MVA, up to 60 MVA in Europe

Why Hitachi Energy

  • Compactly designed, low-weight transformers
  • High-quality manufacturing and design optimization supports required short circuit withstand capability
  • A global manufacturing footprint provides expertise on specific local technical requirements and standards
