Transformers for maritime applications

Reliable, whether in offshore or underwater applications

Pre-magnetizing transformers for marine applications

With transformers, chokes and particularly with premagnetizing transformers, we optimize the power supply in the maritime sector. Since components in shipbuilding and on the high seas are subject to many harsh conditions such as dust or vibration, winding materials must be particularly resilient and robust.

Technology for your on-board power supply

On the waters and seas of this world, our customers trust TRAMAG’s transformer technology for the power supply of their on-board and lighting networks, for control and drive technology and for the premagnetization of medium-voltage transformers.

Maritime standards

Our transformers are also available in compliance with DNV-GL on request.

  • Construction and testing standard DIN EN IEC 61558
  • UL/CSA / according to classification society e.g. DNV-GL
  • Electrical protection classes I and II
  • Insulation classes B, F and H
  • Protection classes according to IP
  • DIN ISO 9001:2015

Specialists for maritime transformers

Many years of expertise are needed to precisely calculate transformer and reactor design in shipbuilding and to develop customized concepts for power supply. Therefore, trust our experienced specialists to develop a suitable solution for your requirements.
