Chokes

We offer customised solutions for inductive components for high-current applications

Applications:

  • Power chokes / filter chokes
  • Earthing reactors
  • DC chokes
  • Interphase transformers

Our many years of experience in the construction of water-cooled transformers have been channeled into the development of these components.

Water-cooling technologies in combination with potting enable compact components with a high power density to be offered.
These products are predestined for use in

  • Wind power plants
  • Solar plants
  • Railway technology

A number of product examples are listed below.
