Power transformers: the manufacturer’s experience serving its customers

Since the early 50’s, all HV and EHV transformers, both medium and large power, are designed and manufactured in Lyons, France at JST transformateurs’ plant. 

Our reputation is derived from our relationship with customers of electrical generation, transmission and distribution, as well as of railway feeders electrical supply, and of major industrial sites. 

Our experience in large scale projects, our close communication with customers, our flexibility to listen to and implement their needs, as well as our deep knowledge of both transformer design technologies – Shell type and Core type – are the keys to our success.
