Remanufacture Your Substation Transformer
Why Remanufacturing Wins
Get your transformers in half the time OEMs can deliver
“They don’t make ‘em like they used to.” Your substation 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 substation transformers running cooler, extending their life expectancy. Solid, older substation 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 substation transformers with base ratings from 10MVA-80MVA and 69kV-230kV with complete Class II IEEE testing.

FAQ's
A1: Reusing the core steel and tank of an existing transformer offers substantial savings in both price and lead time.
A2: The savings are even more dramatic when reusing the LTC within a transformer, which is often!
A3: Our turnaround time is typically months less than new OEM manufacturers which require extensive design time for new transformers.
A4: No sacrifice in quality or life expectancy and all transformers are upgraded to today’s short circuit design standards.
A5: Your remanufactured transformer will have a drop-in form, fit, and function, whereas new typically requires substation design modifications.
