Vacuum Pressure Impregnation (V.P.I.)

Picture1

Vacuum Pressure Impregnation (V.P.I) is a process by which a fully wound electric apparatus stator or rotor is completely submerged in a Resin. 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 higher dielectric strength, increased mechanical strength, greater thermal inductivity, and superior protection against the ingress of water, chemical and containments.

 

A properly globally vacuum pressure impregnated winding will have superior characteristics, which will support a longer and more maintenance free life span.

 

alfanar Technical services company is proud to offer this essential process to its customers and is also proud that this is the only such plant in middle east which has maximum capacity & volume.

As part of our Information Management Systems, a detailed printout of the combined tests which have been carried out will be available to the customer.
