FactoryRegistry lists 605 facilities whose primary industry classification is one of the 1 industry above. This is a list by industry, not a list of makers: Census reports that establishments in these industries produced specialty transformers, including indoor and outdoor instrument transformers, open core and coil transformer units, arc welder transformers, and high-intensity discharge lamp transformers (excluding fluorescent lamp ballasts), in the shares shown above, and does not say which establishments. Where a plant’s own website or a federal registry names what that plant makes, it appears on the plant’s own page with the source named.
