Power transformers are back—engineered and built in Norway.
At Norsk Trafo Service (NTS), you can once again purchase Norwegian-made power transformers.

All core engineering, electrical design, and winding production are carried out in Norway, ensuring full technical ownership, tight quality control, and short decision paths. This gives our customers direct access to the people who design and build the transformer—making collaboration faster, clearer, and more flexible when project requirements evolve.
We combine decades of hands-on transformer experience with today’s design tools and manufacturing methods to deliver reliable, efficient units with long service life. Whether you need a power transformer in the 2–40 MVA range up to 132 kV, or a tailored industrial solution, you’ll receive a transformer built with Norwegian craftsmanship—and backed by a team that stands behind every detail.
