Vacuum Pressure Impregnation (VPI)

Vacuum Pressure Impregnation (VPI)

  • A winding that undergoes VPI is virtually impervious to oil, moisture and chemical contaminants.
  • Results in the greatest mechanical strength for windings, a cooler running motor, improves performance and reliability and extends machine life.
  • Can be used for AC and DC motor stators, armatures, field coils and transformers.
  • Schulz has two independent VPI systems in-house, specific to the Schulz insulation system and to EPRI, respectively.
  • Post VPI windings will pass spray and immersion hi-pot testing.
