Equipment For Vacuum Pressure Impregnation - VPI Equipment

Equipment for vacuum pressure impregnation - VPI Equipment

Equipment Description

This kind of equipment is mainly application of insulation processing for electrical products, such as high voltage motor, generator, H class dry type transformer, power capacitor, cable insulation, and motor repairing, etc. For example, coil winding of motor or transformer can be evaporated at vacuum condition to reduce influence from moisture, air or other impurities. With pressure imoregnation, resin can be immersed into inner side to make the high insulation class. VPI equipment is also used in material industry for improving material performance.

What Is Vacuum Pressure Impregnation (VPI)

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.
