Derived from Transformer types and Largest rating.: Power 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; phase-shifting; reactor; rectifier/industrial; distribution 3
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.: 1,800 3
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.: Conventional power/GSU up to 900 MVA; phase-shifting transformer throughput up to 1,800 MVA (a different rating basis); industrial MV/MV up to 100 MVA 3
Highest voltage kV Highest voltage class the maker publishes or has delivered, in kV (AC system voltage; HVDC noted under Voltage classes).: 550 3
Voltage classes Voltage classes and BIL as the source states them, by product or plant.: Power and phase-shifting product scope through 550 kV; industrial MV/MV through 52 kV 3
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.: five production plants in Italy, including Ospitaletto (Brescia) and Legnano 2
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.: Italy 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.: 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 2
Capacity expansion Announced transformer capacity expansions: amount in the original currency, place, announcement date, target date and output change. US and EU projects first.: Not published
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).: Not published
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.: Not published
Data center product or order The named data center line, or the disclosed order with value and date.: Not published
Parent or owner Parent company or owner where the source states one.: Not published
HQ country Country of the maker's headquarters.: Italy 2
HQ region Region of the maker's headquarters.: Europe 2
Legacy brands and names Sourced former names and acquired transformer businesses, retained on the current maker row to avoid duplicate supplier counts.: Not published
