TDT – Tri Dimensional Transformers

A new energy efficient transformer design with a stabilised structure offering greater performance with less material and production costs.

In comparison to conventional transformers, the TDT wound core drastically decreases the no-load current and noise level. This innovation provides significant savings in operating costs.

The Tri Dimensional Transformer (TDT) is a new energy efficient transformer design with a stabilised structure offering greater performance with less material and production costs. In comparison to conventional transformers, the TDT wound core drastically decreases the no-load current and noise level. This innovation provides significant savings in operating costs.

The energy efficient advanced technology offers:

  • Continuously wound core without air gaps, reducing magnetic reluctance
  • Provides a symmetrical 3 Phase magnetic circuit
  • Optimised utilisation of core material in terms of magnetic flux distribution
  • Almost round leg shape with 96% fill-factor of the core leg circle
  • Smaller footprint with approx. 25% reduction in core area
  • Reduced weight for transport, handling and installation
  • Reduced no-load loss provides a more competitive and environment friendly solution
  • Greater efficiency to reduce operational costs during the transformers life cycle
  • Reduced harmonics and inrush current
  • Reduced sound level and improved EMC.

TDT offers great benefits:

  • Symmetrical and stable structure to guarantee long-term safe operation
  • Compact size
  • Efficient, 20-30% lower no-load loss with the same material usage
  • Reduced and constant sound level, 5-10dB improvement in contrast to a standard stacked core transformer
  • Reduced operational cost during the transformer life cycle
  • Easy to handle with simple installation
  • Up to 30% lighter than traditional transformers.
