products: Vacuum Pressure Impregnation (VPI)
- Vacuum Pressure Impregnation (VPI) system has been used in the high voltage motor and generator manufacturing and service industries
for many years. It is the most effective process to-date for removing air, moisture and volatile from the winding prior to varnishing.
- MES service workshop in Singapore has now equipped with a modern VPI system. Its process tank has a dimension of 2.5 metres
diameter x 4.0 metres length, i.e. a volume of 20 cubic metres (700 cubic feet).
The VPI system specially designed by the Epoxylite Corporation of USA.
The process tank is capable to withstand a working pressure from full vacuum to 7 bars (or 100 psig). The use of Epoxylite #478
solventless resin in our VPI system allows us to obtain a completely filled 100% solid insulation structure and a smooth continuous
coating on the external surfaces of the wound coils.
- With this state-of-the-art VPI system, we are able to provide complete and void free impregnation for form-wound medium (2.3 – 5.0 KV)
and high voltage (6.6 – 13.8 KV) stator, rotor and armature winding.
