National Industri and Richard Pfeifer
The very begnining
Richard Pfeifer (RF) was established in Sarpsborg a city located south east in Norway February 1920. In the very begnining RF produced new power transformers for the Norwegian market.
In 1970 RICHARD PFEIFER was acquired by NATIONAL INDUSTRI (NI), and NI changed the production from power transformers to industrial special transformers (shell type). NI aimed for the global market and made it. NI exported furnaces and rectifier transformers all over the world. And by the end of 1988 NI was the leading company for furnace transformers production in the world.
NATIONAL INDUSTRI was incorporated in to ABB in 1988. In 1994 they decided to close the plant in Sarpsborg and move it to ABB Drammen. Many of the employees moved along with the company, but not all. Some of the former employees of NATIONAL INDUSTRI and ABB decided to carry on with transformer production in Sarpsborg, and therefore Norsk Trafo Service (NTS) where established in 1996.
