About Seko

Over 25 års erfaring innen produksjon og leveranse av transformatorer og elektroniske løsninger.


SEKO was established in 1970 to produce transformers for automation onboard ships after the change to AC powering.

In 1976 the ship building declined. Seko then started the development of radio remote controls, first for the Norwegian public road administration, and SEKO delivered RemoteControls for ferry landings in Norway, Sweden and Denmark. Until 1978 SEKO also was the importer and distributor of Commodore computers in Norway.

Seko grasped new opportunities and was the first supplier of joystick operated maneuvering for offshore supply vessels based on computer control. Seko also delivered wireless data transfer systems to Norwegian processing-industry such as smelting plants.

The electronics-department in Seko was sold in 1985 and we have since then concentrated on the production of transformers. In 1993 we developed, as one of few in Europe, transformers for use in Ex-areas and we have developed filters for over-harmonic currents in large lighting installations. Both products involving winding technology derived from the transformer production.
