Cast resin transformers

Cast resin transformers

Our cast resin transformers are mechanically and thermally stable with regard to changing loads, short circuits and extreme climatic conditions. They correspond to climate class C2, environmental class E2 and fire class F1. Thanks to our various series concepts, we have the right solution for your specific requirements for every application.

In addition to the "Standard" series for power distribution transformers with molded vacuum casting for the high-voltage coils and prepreg insulation for the low-voltage coils, we as a transformer manufacturer can offer you the right special transformers for your needs with the "Modular" and "Individual" series : for example higher mechanical ones Strength and resistance to aggressive atmospheres thanks to the vacuum potting of the low-voltage coils. We use aluminum or copper as the conductor material for our transformers, depending on customer requirements and specifications.
