Vacuum Pressure Impregnation Transformer

•The enhanced heat dissipation of VPI transformers extends their lifespan and contributes to stable performance under varying load conditions.

•An additional benefit of VPI transformers is their reduced operational noise. The resin impregnation helps to dampen vibrations and minimize the humming sound often associated with transformer operations.
