VPI Transformers utilise high temperature class H rated insulation – products such as Nomex, Glastic, Kapton and Glass Tape, etc. form the insulating materials, with the windings being dried out and vacuum / pressure impregnated using a silicone or polyester based varnish before being baked to cure the varnish.
In a vacuum impregnated transformer the primary and secondary winding is impregnated with resin within a vacuum chamber. The winding is made in the form of foil or strip. For higher voltage applications the winding is made in the form of a disc. The winding can be physically seen by opening the door of the transformer.
