What are the advantages of rewinding/remanufacturing vs. alternative of buying new?


  • Reusing the core steel and tank of an existing transformer often offers substantial savings in both price and lead time. The savings are even more dramatic on LTC transformers.
  • Our turnaround time is typically half that of new manufacturers.
  • No sacrifice in quality or life expectancy and all transformers are upgraded in design to today’s short circuit standards.
  • Plug-and-play functionality into the substation.
  • Environmentally friendly reuse of components.
What repair options can you offer for a failed transformer with rectangular core & coil design?
A. Jordan Transformer can “convert” some transformers to circular core & coil design with all new core steel and new disc windings. Our clients have found this to be an excellent option. We have done more than 25 “rectangular to circular” core & coil conversions.
Do you buy surplus transformers?
A. No, we remanufacture your substation power transformers that are failed or gassing. 
Do you work on furnace transformers and rectifiers?
A. Yes - we are experts with both.
