Abstract
A distribution transformer adapted for mounting to a utility pole. The distribution transformer includes a plurality of coil assemblies mounted to a ferromagnetic core. Each of the coil assemblies includes a low voltage coil and a high voltage coil. The low voltage coils are connected together and the high voltage coils are connected together. An encasement comprised of an insulating resin encapsulates the core and the coil assemblies. The encasement includes a substantially annular body and a pair of high voltage bushings extending outwardly from the body. Terminals extend from the high voltage bushings and are connected to the high voltage coils.
