Vacuum Pressure Impregnation (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.
VPI (Vacuum Pressure Impregnation) vastly improves performance and reliability even in the harshest working environments. Machines last longer and require less maintenance.
Vacuum Pressure Impregnation is a process which provides positive pay-back over a short period of time.
ERIKS have several VPI plants operating in the UK.
The largest of our plants is in Chesterfield, Derbyshire, uses 100% solids epoxy resinous impregnants.
All the other Vacuum Pressure Impregnation plants utilise 100% solids polyester resins.
These VPI plants have been designed to process the complete range of electrical plant - from small DC coil, wire wound stators right up to large 11,000 volt stators. Machines can be tested under water before despatch to you.
