At AFP Transformers, our Epoxycast transformers provide several benefits to traditional dry type transformers. Epoxycast transformers can withstand high power surges as a result of higher BIL ratings. The coils are directly cast into the mold under pressure, instead of using vacuum pressure impregnation to apply resin to the coils. The coil is deeply embedded in the epoxy material, protecting coils from contaminates and holding the windings in place during power surges. The secondary coils are standard dry type processed with a polyester resin in VPI process.
Epoxy material is strong and requires little maintenance. As a dry type transformer, there are no hazardous liquids or materials to pose a safety risk. Since they do not contain hazardous materials, Epoxycast transformers do not require transformer vaults that limit placement options and significantly add to the cost of liquid transformers.
AFP Transformers manufactures a wide range of transformers from 600V to 34.5 kV voltage classes. Epoxycast transformes are used in a variety of application including control power transformers, pad-mount distribution transformers, and neutral grounding transformers used in utility and cubicle applications.
