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.
- Power and 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.
- power; GSU; autotransformer; substation; distribution; pad-mount; pole-mount; network; shunt reactor; solar/wind (renewable); data center; voltage regulators; collector step-up 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.
- 1,200 1
- Smallest rating kVA Smallest published rating, in kVA. Shows how far down the distribution range a maker goes.
- 5 2
- Product range The kVA/MVA range as the maker states it, by product line.
- Residential/commercial 5-1,000 kVA; network 300-2,500 kVA; industrial and renewable 225-15,000 kVA; medium power 5-100 MVA; large power 100-1,200 MVA 2
- Highest voltage kV Highest voltage class the maker publishes or has delivered, in kV (AC system voltage; HVDC noted under Voltage classes).
- 800 1
- Voltage classes Voltage classes and BIL as the source states them, by product or plant.
- power transformers through 800 kV primary (web); brochure lists large/medium power up to 500 kV; distribution up to 34.5 kV 1
- 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.
- Apodaca/Monterrey, Mexico; Waukesha, Wisconsin, United States; Goldsboro, North Carolina, United States; Shreveport, Louisiana, United States; Canoas, Brazil 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.
- Mexico; United States; Brazil 2
- 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.
- Yes 2
- 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.
- Not published
- Capacity expansion Announced transformer capacity expansions: amount in the original currency, place, announcement date, target date and output change. US and EU projects first.
- $140M second plant, Goldsboro, North Carolina, announced 2025-05-14, ~200 more medium power units/yr and doubled Goldsboro capacity by 2030; new three-phase pad-mount line in Shreveport, Louisiana (1,500+ units/yr) and doubled single-phase pad-mount output 4
- 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.
- 140 4
- Expansion region Where the announced capacity expansions are: US, EU, both, or only elsewhere (Other).
- US 4
- Certifications and standards Quality certifications, listings and design standards the source names (ISO 9001, IEEE C57, IEC 60076, EU Ecodesign Tier 2, utility approvals).
