Vacuum Pressure Impregnation Plant
The VPI process provides many benefits to the user. it completely
seals the windings against moisture and vibration, provides greater
mechanical strength, and improved corona protection.
it vastly improves performance and reliability even in the hardest
working environments. machines last longer and require less
maintenance. VPI is a process, which provides positive payback over
a short period of time.
Goltens has the biggest VPI plant operating in the region. The plant
is 3m diameter x 3m depth.
The equipment is designed to process the broadest range of products,
from small AC/DC could upto 11 KV machines

The VPI system is used after the motor stator
has been renowned to guarantee reliability and consistency. The
three step process works as follows:
A
transfer valve is opened and the appropriate medium (varnish/
resin) is transferred from a storage tank into the processing
tank until the stator windings are completely immersed.
The
transfer valve is then closed and the tank is held under vacuum
for a period of time before being pressurized to force the
medium through the multiple layers of wire and insulation
(filling all voids)
