Power Transformers

Norwegian Power Transformers

We are a Norwegian manufacturer and supplier of power transformers. We deliver reliable units from 2 to 40 MVA and up to 145 kV. Our transformers serve demanding grid and industrial applications. We design them for high efficiency, robust performance, and long service life. Our engineers build on decades of hands-on transformer experience.

Our story starts with a strong Norwegian transformer tradition from the first half of the 1900s. That heritage shaped our craft, our technical curiosity, and our quality mindset. We have carried this know-how forward through people, proven methods, and continuous learning. We also combine it with modern design tools and updated standards. This approach helps us deliver consistent, dependable results.

Today, we bring power transformer manufacturing back to Norway. This step strengthens local capability for industry and the power sector. We support your project from start to finish. We handle concept, design, production, testing, and after-sales support. Contact us for a quote, or reach out for a technical transformer discussion.
