Vacuum Pressure Impregnation Plant

Vacuum Pressure Impregnation (VPI) is a process by which a fully wound electric apparatus stator or rotor is completely submerged in a Resin/Varnish.

Through a combination of dry and wet vacuum and pressure cycles, the resin is assimilated throughout the insulation system. Once thermally processed, the impregnated windings become a monolithic and homogenous structure.

The resulting benefits are:

Improved electric motor efficiency

Higher Dielectric Strength

Increased Mechanical Strength,

Greater Thermal Inductivity,

Reduced probability of motor failure

Superior Protection against the Ingress of Water, Chemical and Containments.
