ABSTRACT:
A dry-type, resin-encapsulated transformer coil that includes multiple layers formed from a length of conductive material, and multiple cooling ducts that are formed of thermoplastic material and spaced between the layers of conductive material. The thermoplastic material forming the cooling ducts and the resin that encapsulates the multiple layers of conductive material are thermally and electrically compatible.
