Why Remanufacturing Wins
Get your transformers in half the time OEMs can deliver
“They don’t make ‘em like they used to.” Your power transformer is valuable. Don’t throw that away: remanufacture, reuse, and save. In the 20th century, substation transformers were designed with reliability in mind—thick steel tanks, spacious tank interiors, and plenty of copper. This “greater design margin” approach kept power transformers running cooler, extending their life expectancy. Solid, older power transformers are the key to remanufacturing America’s power grid to be stronger than ever.
At Jordan Transformer, we specialize in rewinding and remanufacturing your power transformers with base ratings from 10MVA-80MVA and 69kV-230kV with complete Class II IEEE testing.
