500kva vacuum impregnated dry type transformer Class H 180℃ 4160 V to 208Y DOE 2025 VPI Medium Voltage transformer
VPI (Vacuum Pressure Impregnated) Transformer is a type of transformer or to be more specifically a type of a dry type transformer. In this type of transformer the transformer windings are covered with a special type of resin with the application of vacuum pressure.
The insulation scheme of H-class three-phase dry-type transformers is designed with 180℃ H-class materials and is made of H-class solvent-free insulating varnish vacuum pressure impregnation and high-temperature curing treatment and have extremely good electrical and mechanical properties.

Key Features of VPI Transformer
- High Thermal Endurance:The VPI transformers are designed and developed to deliver high efficiency even in high temperature applications. These transformers can manage thermal stress much more efficiently when compared to the oil type transformers.
- Extended Transformer Winding Life:Due to the VPI process the insulation of the transformer winding is of highest quality. This protects the winding from all types of dust, contamination, and moisture ensuring the winding will not short and thus extending transformer life.
- Available in Multiple Power Rating:VPI Transformer are available for wide range application in multiple power ratings. All sizes and power ratings offer the same level of thermal endurance, high performance, and reliability.
- Minimum Maintenance Requirement:As there is no oil being used in the VPI transformer for insulation and cooling purposes, there is no probability of any type of oil leak or oil related maintenance work.
- Reduced Noise and Vibration Levels:VPI transformers are designed and developed in such a way that they operate very quietly as compared to a regular oil type transformer. Lack of an oil pump and other parts like this also reduce the noise and vibration level. This makes them the perfect transformer for use in noise sensitive areas.
