Facts
Source per value- Segment Power when the maker publishes power, GSU, HVDC, autotransformer or reactor products or a rating above 20 MVA; Distribution when it publishes distribution, pad-mount, pole-mount, network or dry-type products; both when it publishes each. Derived from Transformer types and Largest rating.
- Distribution 1
- Transformer types Product types the maker lists, separated by semicolons: power, GSU, autotransformer, HVDC, shunt reactor, substation, distribution, pad-mount, pole-mount, network, dry-type (cast resin, VPI), mobile, rectifier/industrial, renewable and data center lines.
- distribution; substation; solar/wind (renewable); data center 1
- Largest rating MVA Largest verified published rating in the cited product or regional scope, in MVA. Product range identifies base, forced-cooling, phase-shifter throughput or group-history claims; these rating bases are not interchangeable. Planned future ranges are described separately.
- Not published
- Smallest rating kVA Smallest published rating, in kVA. Shows how far down the distribution range a maker goes.
- Not published
- Product range The kVA/MVA range as the maker states it, by product line.
- Medium-voltage distribution transformers; about 7 GW of annual transformer capacity at Loeches 1
- Highest voltage kV Highest voltage class the maker publishes or has delivered, in kV (AC system voltage; HVDC noted under Voltage classes).
- Not published
- Voltage classes Voltage classes and BIL as the source states them, by product or plant.
- Not published
- Plants Transformer manufacturing locations, city and country. Planned plants carry their target date. Location lists identify verified sites and may not cover every factory in a global group.
- Loeches (Madrid), Spain; 17 industrial plants worldwide 1
- Plant countries Countries with verified operating transformer manufacturing in the cited scope; not necessarily the complete global footprint. Component and service-only sites do not establish new-unit manufacturing.
- Spain 1
- US plant Yes when an operating US transformer plant is verified; No when the source shows the maker's plants and none is in the US. Empty means not verified.
- Not published
- EU plant Yes when an operating transformer plant in an EU-27 country is verified (the UK, Norway, Switzerland and Turkey do not count). Empty means not verified.
- Yes 1
- Capacity expansion Announced transformer capacity expansions: amount in the original currency, place, announcement date, target date and output change. US and EU projects first.
- EUR 15M planned at Loeches over five years from 2025 to expand capacity and digitalise (after EUR 15M in the previous five) 1
- Largest US/EU expansion $M Largest single announced US or EU transformer capacity investment, in US$ millions, where the source states a dollar amount. Euro amounts stay in Capacity expansion unconverted.
- Not published
- Expansion region Where the announced capacity expansions are: US, EU, both, or only elsewhere (Other).
- EU 1
- Certifications and standards Quality certifications, listings and design standards the source names (ISO 9001, IEEE C57, IEC 60076, EU Ecodesign Tier 2, utility approvals).
- Not published
- Data center offer Yes when the maker markets transformers for data centers or has disclosed a data center transformer order. Empty means not found.
- Yes 1
- Data center product or order The named data center line, or the disclosed order with value and date.
- MV transformers and distribution switchgear; more than 50 data center projects worldwide, 22 in Spain 2
- Parent or owner Parent company or owner where the source states one.
- Velatia 1
- HQ country Country of the maker's headquarters.
- Spain 1
- HQ region Region of the maker's headquarters.
- Europe 1
