VPI dry type transformer coils are vacuum pressure impregnated in high temperature polyester varnish. The process includes complete submersion in varnish under vacuum and pressure and regulated curing usi rig statistically process controlled equipment to ensure consistency.
VPI transformers utilize a step-lap core construction to ensure optimum performance and minimal sound levels. The mitered core joints allow efficient flux transfer alorig natural grain lines between the core legs and yoke. The step-lap construction further enhances the efficiency of the joint by reducing joint fringing, which reduces core losses and exciti rig current.
