VACUUM PRESSURE IMPREGNATION 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 windings of motor or transformer can be evaporated at vacuum condition to reduce influence from moisture, air or other impurities. With pressure impregnation, 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.
