Nizhny Novgorod industrial company “Electrical Machines” is the successor of the enterprise «Electropromremont», which controlled the whole field of the electrical industry. We inherited the archives with the documentation for the service of transformers from nearly the whole of Russia. So, we are well aware of the condition of transformers at a number of electricity generating plants, metallurgical and engineering plants.
NPK «Electrical Machines» JSC extends back over more than forty years of history and it occupies the leading position in the market of production, repair, modernization and reconstruction of transformers.
