We design your transformer or substation to your specification, have it built under our own brand, and carry the compliance responsibility through to delivery on site.
Failure, repeated summer tripping, an obsolete unit or a load that has grown : give us the rating plate and the room constraints, and we return an equivalent or better-sized unit, Tier 2 compliant, delivered price with transport included, with a single contact. Controlled 15–18 week lead time.

See replacement / retrofit →Since 2021, procurement times for grid components have almost doubled: the International Energy Agency reports up to four years for a large power transformer, with prices up around 75%. Data centers, renewables, grid reinforcement, electric mobility: everyone is ordering at once, from the same production lines. The result: lead time has become the first purchasing criterion, ahead of price.
In France the squeeze is structural. The distribution system operator plans to move from 15,000 to 20,000 distribution substations installed per year by 2027, and lifted its industrial purchasing to €4.5 billion in 2025, roughly 35% above 2022. That demand takes first call on European production capacity; private projects queue behind it.
Orders of magnitude for custom distribution transformers; actual figures vary by segment, manufacturer and configuration. Market context: IEA, Building the Future Transmission Grid (2025); France figures: Enedis investment programme and industrial purchasing (2025). Our lead time is delivered to site, shipping and formalities included, not ex-works.

No magic: building a transformer takes a few weeks. It is everything around it that stretches, and that is what our model is built on.
From 100 to 3,150 kVA, our ranges avoid re-engineering on every order. The base design is done: only your specification has to be integrated.
No queue behind saturated order books: capacity is planned at our partner factories, and your production slot is fixed when you order.
Manufacturing, acceptance testing and shipping run end to end, right to your site. One point of contact, one lead time: the delivered one.
From the MV grid to your LV board: tell us what goes in between.
Type, power, voltages, vector group, cooling… configure your unit in a few minutes. No automatic pricing : every transformer is custom-built. First reply within 48 h, firm quotation within 5 working days.

See warranty & after-sales →Placing a transformer on the EU market carries clear obligations, and as the brand, we carry the manufacturer's obligations: CE marking, technical file, EU Declaration of Conformity, Tier 2. For the import itself, either your company acts as importer of record (we supply the complete documentation pack) or we arrange delivery through an EU-established importer.
EU Declaration of Conformity and full technical file, under our manufacturer responsibility.
Regulation (EU) 548/2014: capped losses, mandatory since July 2021. Verified at the factory.
Type, routine and special tests; KEMA / TÜV witnessed reports on request.
Hazardous substances controlled and documented across all components.
Producer registration and eco-contribution handled, mandatory from the very first unit.
For projects in France, our designs also align with the applicable NF standards (NF EN 60076, NF C 13-100 / 13-200) and DSO requirements (Enedis / RTE); see the French version of this site for the full France-specific documentation and guides.
