About the Company

JST transformateurs draws on over more than 50 years experience in design, manufacturing, and maintenance of electric transformers to meet the needs of its ever evolving clients across the five continents. Our employees here at JST transformateurs maintain since the start a tradition of technical leadership. Hence, JST transformateurs has helped Electricité de France (EDF) in the development of manufacturing and transportation of electricity in France, stimulating our engineers to think up innovative solutions in order to provide adapted responses to extremely demanding technical specifications. Until recently JST transformateurs was entrusted to design and manufacture transformers with an energy evacuation system for the new EPR technology nuclear power plant, currently under construction in Flamanville, France. Concerning the railway network, this tradition is no weaker. JST transformateurs was the pioneering designer for the transformers that were onboard high-speed trains, during the development of the first TGV in partnership with Alstom and France’s national railway authority (the SNCF). JST transformateurs is still renowned for its very precise know-how which allows it to optimise the weight and the size of its products. Conscientious of its social and environmental responsibility, JST transformateurs leads an independent strategy for sustainable development with the view of a long-term partnership with its clients and its suppliers.
