What is VPI process?

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.

What is VPI transformer?

The VPI process uses polyester resin. The coils are then cured in an oven. The VPI process is better than the standard dry-type transformer because it includes pressure in addition to vacuum. This process allows better penetration of the varnish in the transformer coil.

FAQ

1. Where is your main market?

We had exported our transformers to more than 30 countries in the world, our main market is Africa countries, South and North American countries, and Asia countries.

2. What certificate do you have?

We have KEMA, CESI, CTQC type test report for our transformers.

3. How long is your delivery time?

30 days after drawing confirmed by buyer for distribution transformers below 5000kva, bigger transformers depend on the capacity and components, normally 30-90days(with imported components)
