CE Certificate motor windings vacuum pressure impregnation machine
Extend the life and operation of your motor -- Choose a motor that utilizes vacuum pressure impregnation to protect and maintain void-free electrical windings.
1. What is VPI (Vacuum Pressure Impregnation)?
Vacuum Pressure Impregnation (VPI) is a process that uses vacuum and pressure to seal porous materials with varnish or resin. The process is used primarily for high-voltage motors and generators to fill gaps in materials to create a void free insulation in various devices.
Industrial electromechanical equipment is designed for durability to provide reliable function and increased longevity, but age, temperature, and environmental factors can degrade porous metals over time. The process of impregnation seals porous materials with varnish or resin, improving the function and longevity of equipment.

4. General process of VPI
YICHENG specializes in vacuum pressure impregnation equipment manufacturing, which is more effective than traditional dip-and-bake methods and is better suited to high voltage motors and generators. Our basic vacuum pressure impregnation motor repair process comprises several steps.
5. Application of VPI
VPI systems are used by the electrical industry in the processing of coil windings, transformer components, power cables, fiberglass laminations, cores, paper products and other items.
Impregnation has been in commercial use for over 60 years and continues to be the preferred method for ensuring pressure tight components in fail safe applications. The aerospace, automotive, food processing and oil and gas industry use vacuum impregnation to improve the quality of their base castings, conserve resources and reduce scrap.
