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. ## Value for You --- Shorter delivery time than an OEM Reuse original high reliability design concepts Reuse steel components—tank, core, and frame Upgrades only when requested or needed ## Remanufacturing Power Transformer Process Flow 1 Discovery Freight ↓ Un-Tank ↓ Inspection ↓ FSOW Report 2 Reengineer Electrical ↓ Leads ↓ Controls 3 Re-build Rewind ↓ Core re-Build ↓ Radiators ↓ Assemble ↓ Tank\* 4 Test Preliminary ↓ Full IEEE Testing\*   *\* indicates typical customer witnessing opportunities during the process* 5 In-service Final Paint ↓ Freight ↓ Installation ## Dedicated Remanufacturing Facility Capabilities Rewinding means a custom rebuild for your unique transformer and substation requirements.
