    Abstract: A method of forming a transformer coil, wherein first and second fibrous layers are provided. Each of the first and second fibrous layers includes a fabric formed from a plurality of interconnected fibers and a plurality of spacers affixed to the fabric and protruding therefrom. A conductor layer is disposed over the first fibrous layer such that a first side of the conductor layer contacts the spacers of the first fibrous layer. The second fibrous layer is disposed over the conductor layer such that a second side of the conductor layer contacts the spacers of the second fibrous layer. A resin is applied so as to cover the conductor layer and the first and second fibrous layers.

    Abstract: A distribution transformer having a coil assembly mounted to a ferromagnetic core. The coil assembly includes a resin-encapsulated low voltage coil mounted to the core, a resin-encapsulated first high voltage coil disposed around the low voltage coil, and a resin encapsulated second high voltage coil disposed around the first high voltage coil. The first high voltage coil is separated from the low voltage coil by an annular first space, and the second high voltage coil is separated from the first high voltage coil by an annular second space. The low voltage coil and the first and second high voltage coils are arranged concentrically. The low voltage coil and the first and second high voltage coils have different axial lengths.

    Abstract: La presente invención se refiere a un transformador y un método para manufacturar el mismo, en donde el transformador incluye un montaje de chapa montado a un soporte de un núcleo. El montaje de chapa incluye una chapa de bajo voltaje y una bobina de aislamiento colocada sobre la chapa de bajo voltaje. La bobina de aislamiento está compuesta de un material aislante e incluye una pluralidad de tiras guía que definen una pluralidad de series de muescas alineadas. Una chapa de alto voltaje es montada a la bobina de aislamiento e incluye una pluralidad de devanados en disco colocados en la serie de muescas alineadas, respectivamente. Cada uno de los devanados en disco comprende capas aislantes y capas conductoras concéntricas alternadas. Las capas conductoras tienen una relación de anchura a espesor de más de 20:1.

    Abstract: A transformer coil assembly (100) includes a first layer (130) having a plurality of fibers interconnected to form a fabric (310) and a plurality of spacers (330). Each spacer is affixed on a first side of the spacer to the fabric and protruding from a first surface of the fabric. A second layer (140) has a conductor (145) in contact with at least one of the plurality of spacers on a second side of each spacer that opposes the first side. The first and second layers are covered by resin (110).
