In 2012, SPX Transformer Solutions began shipping Large Power transformers from its expanded facility in Waukesha, Wisconsin. This 154,000 square foot expansion increased SPX Transformer Solutions’ production capability to 1200 MVA, 345 kV. Utilizing state-of-the-art production facilities and equipment, our well-trained and experienced employees and engineers are proud to offer the domestic market a US produced alternative for your Large Power transformer needs.
     

Core Stacking & Cutting

  • Automatic cutting machines and customized, state-of-theart stacking table from GEORG include swing shear lines for cost-effective production of highest quality complex power transformer cores
  • Advantages of this system include cutting of laminations with absolute minimum burr, high level of stacking accuracy and careful treatment of highly sensitive surfaces
  • Three-leg or five-leg geometry for three phase transformers (two-leg or four-leg for single phase)
  • Step lap construction utilized to reduce no load losses and noise level

Coil Winding

  • Fully enclosed and environmentally-controlled coil winding room
  • Larger windings produced on state-of-the-art Tuboly vertical and horizontal winding machines
  • Coils up to 2.8m (9.2 ft.) in diameter
  • Interleaved, shielded disc, helical, disc or layer construction (depending on voltage and impulse rating)

Drying

  • State-of–the-art Hedrich front entry vapor phase chambers utilized for coil stabilizing and core/coil assembly drying, including iso-static pressing for coil stabilization and precise measurements, ensuring compliance to design standards
  • Optimizes heat transfer, process time and residual moisture
  • Iso-static sizing leads to good elastic behavior and ‘sizing pressure’ is maintained during service to provide safety against short circuit forces
  VaporPhase
     

Assembly

  • Humidity and dust controlled environment to minimize potential for contamination and moisture ingress, ensuring <0.5% moisture content in the finished transformer
  • Low humidity “desert” room for final adjustments after vapor phase prior to transformer tanking
  • 500 ton crane capacity
  TransformerAssembly
     

Testing

  • Faraday Cage test lab electrically and mechanically isolated to minimize outside interference in test results and ambient partial discharge <5pc
  • State-of-the-art Haefely test equipment utilized to ensure that each transformer meets or exceeds industry standards and customer specifications
  • Capable of performing routine and special tests, including, dielectric, heat run and frequency response analysis (FRA) as per standards
