Due to our experience, based on more than 30 years of work in the field, JST Transformateurs has references on all continents, both regarding assembly supervision and turnkey assembly.

We have supplied and installed more than half of the French nuclear pool with 400 KV step-up transformers (benches of 1,080 MVA, 1,650 MVA, and 1,710 MVA).

Using a turnkey assembly system, we manufacture for RTE, the French transport network, 225KV and 400 KV transformers and autotransformers, whose ratings go from 40 to 600 MVA.
