Vacuum Pressure Impregnation – VPI
We offer VPI of different types of items – such as generators, electric motors, transformers and coils. It is an impregnation with a resin under vacuum and pressure – it gives the highest possible penetration of the resin in the coils. The treatment ensures the longest attainable service life.
We can handle items as large as 2,5 x 3,6 meters.
The benefits of VPI include:
- 1 VPI equals 8-10 times conventional ”dip and bake” method
- Machines last longer
- Insulationclass H – enhanced insulation quality
- Eliminate dead airspaces that cause hot sports within coils
- Completely seals the windings against moisture, salt, oil, chemicals etc.
- Provides greater mechanical strength
- Provides a cooler running motor due to superior heat dissipation
- Reduces vibrations and noise level
- Reduces risk for loose windings
