Cast resin transformers

Each of our dry transformers is tested before being shipped to the customer. They are smaller, safer, more environmentally friendly and more cost-effective than oil-fired transformers of the same power class. We provide the complete electrical installation from transformers to distribution rails and main distribution system.

Unmatched performance

Each of our cast resin transformers is tested before being shipped to the customer. That's why we offer a two-year warranty on all our standard transformers. Our wide range of sealed cast resin transformers is available from 160 kVA to 20 MVA.

Our sealed cast resin transformers are smaller, safer, more environmentally friendly and more cost-effective than oil-fired transformers of the same power class. Our E3-C2-F1 rated cast resin dry transformers offer unrivalled performance even in the harshest conditions (IEC 60076-11).

With a partial discharge of up to 10 pC, the Green T.HE is more resistant to stress and has a longer service life. Our dry-type transformer is lightweight and compact. Its new magnetic core makes it adaptable to all kinds of needs.

A greener and more user-friendly choice

Up to 2.5% of all energy consumed in the EU is wasted due to transformer losses, according to the European Commission. Our Green T.HE cast resin transformers, which comply with the Ecodesign Directive, ensure that energy consumption can be consistently reduced. This leads not only to financial savings, but also to a reduction in carbon dioxide emissions.

Innovative materials and design ensure the efficiency and ease of use of our dry transformers. Our connectors are built for easy product connection and the magnetic core ensures high performance and low losses. Yet the sizes of our cast resin transformers have remained the same.
