What is a VPI Dry Type Transformer?

A VPI (Vacuum Pressure Impregnated) Dry Type Transformer is a type of transformer that uses a solvent-free resin to insulate its windings. The resin is cured under vacuum pressure, providing enhanced insulation properties and protecting against moisture and pollutants. This technology not only increases the durability of the transformer but also contributes to its compact size and reduced maintenance needs.
