Veltrium Énergie designs and has your custom transformers and substations built at qualified partner factories — under our brand, our quality control, and our EU compliance responsibility.
Enter your specification: our team comes back with a firm quotation. No automatic pricing — every unit is custom-built.
Spec-only request: we never auto-price. Your specification goes to our engineers, who reply with a firm quotation. You can also simply send us your own technical specification.
Every unit is designed to your specification, built under our brand at qualified partner factories, and compliant with European standards (CE, IEC / EN 60076, Ecodesign Tier 2).
| Range | Technology | Power | Voltage | Typical use |
|---|---|---|---|---|
| Oil-immersed distribution | Mineral oil / ester | 100 – 3,150 kVA | ≤ 36 kV | Grids, industry, outdoor substations |
| Cast resin (dry) | Dry, indoor | 100 – 3,150 kVA | ≤ 36 kV | Data centers, public buildings, sensitive sites |
| MV substation | Packaged, prefabricated (IEC 62271-202) | per transformer | ≤ 36 kV | Grid connection, industrial sites |
| HV substation | Engineered-to-order | up to ~100 MVA | 36 – 170 kV | Renewables evacuation, large sites |
Oil-immersed ONAN, 20 kV → 400 / 230 V, losses compliant with Ecodesign Tier 2 (EU 548/2014). Exact guaranteed losses, mass and dimensions are confirmed with the quotation.
| Power | Typical Ucc | Indicative mass |
|---|---|---|
| 400 kVA | 4 % | ≈ 1.3 t |
| 630 kVA | 4 % | ≈ 1.8 t |
| 1,000 kVA | 6 % | ≈ 2.6 t |
| 1,600 kVA | 6 % | ≈ 3.7 t |
| 2,500 kVA | 6 % | ≈ 5.2 t |
Data centers & IT (K-rated designs for non-linear loads) · Solar and wind (step-up units, bidirectional flow, evacuation substations) · Battery storage and EV charging hubs · Industry and grid operators. Each sector has its constraints — we design for them, not around them.
Sourcing in China exempts you from nothing. Placing a transformer on the EU market requires all of the following — 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.
