Vacuum pressure impregnating tank /VPI/

Vacuum pressure impregnating tank /VPI/

Vacuum Pressure Impregnation (VPI) is a process that uses high pressure up to 600kPa to seal porous materials with varnish. The process is used primarily for high voltage motors and generators to fill gaps in the materials to create a void free insulation in various devices. Transwest specializes in vacuum pressure impregnation, the only technology of its kind in Mongolia, which is more effective than traditional dip-and-bake methods which is better suited to high voltage windings.

Benefits of VPI
The vacuum used in a VPI makes the following components stronger and creates a more solid structure that can withstand:
  • Leaks
  • Cracks (Insulation)
  • Corrosion
  • Moisture
Vacuum pressure impregnation is a more cost-effective solution as it extends the lifetime of products while saving energy.
