18-Pulse Transformers

General Information

  • 18-Pulse: 15 HP through 500 HP


  • Special purpose multi-pulse magnetics can be manufactured to meet specific requirements of your application
  • Each autotransformer reduces the harmonic current at the input of the transformer as well as harmonic voltage distortion from non-linear loads applied to the outputs.
  • Water and wastewater treatment facilities
  • HVAC intallations
  • Pump lift stations


  • 1.5 to 500 HP
  • Core and Coil
  • 60 Hz operation
  • Three phase: 15 — 500 kVA
  • Aluminum windings
  • 150ºC temperature rise with 40°C ambient (customer supplied forced air cooling)
  • 220°C insulation class
  • Cores of high quality electrical steel
