Description

KOLEKTOR ETRA power transformers, oil transformers from 10 to 500 MVA and up to 420 kV. Areas of expertise recognized in the production of hydroelectric power, offshore wind and underground transmission and distribution The beginnings of the Kolektor-Etra go back to 1933 In the 1960s, by the license contract with the French factory Alstom Savoisienne, the company specialized in the production of transformers up to 150 mega volts ampere and 145 kilovolts nominal voltage. In 2010, ETRA 33 became part of the Kolektor Technology Group under the name Kolektor ETRA. With its own development and innovative approaches, Kolektor-Etra is now one of the largest suppliers of high-tech transformers in Europe. Our research and development department is proud of experienced professionals, reinforced by a team of young engineers who works in concert with academic specialists, the whole that guarantees technological progress. By using grain-oriented electrical transformer steel, including technologically advanced manufacturing and the "Step Lap" stacking system, we are able to get base-core losses from the magnetic core and reduced noise level of our finished products. We market our products in more than 40 countries, on 5 continents, in the tropical jungles and in the deserts, in the glacial north and on the coast, on the marine platforms in the engine rooms of hydroelectric and thermal power stations although in the hostile environment of industrial facilities.
