    摘要: A three-phase dry distribution transformer adapted for mounting outdoors on a pad or to a utility pole. The distribution transformer includes one or more winding assemblies mounted to a ferromagnetic core. Each winding assembly includes a low voltage winding and a high voltage winding. In each winding assembly, an encasement comprised of an insulating resin encapsulates the low voltage and high voltage windings. The encasement includes a body and a pair of high voltage bushings and a pair of low voltage bushing.

    摘要: Surface modified electrical insulation system including a hardened or cured synthetic polymer composition including at least one filler, wherein the surface of said synthetic polymer composition is modified by being coated with a thin coating. The thin coating is applied by a plasma enhanced chemical vapor deposition (PECVD) with a thickness within the range of about 50 nanometer to about 50 μm; and/or a by a sol-gel technique with a thickness within the range of about 0.5 micron to about 1 mm. The thin coat is an electrically non-conductive polymeric material having a melting point which is distinctly higher than the melting point or degradation temperature of the synthetic filler containing polymer composition.

    摘要: A protective coating system for application to exposed surfaces of a transformer core prevents corrosion of the core. The protective coating is suitable for use in industrial and marine environments where many factors impact the life of the transformer core. The protective coating comprises at least three coating layers. The first coating layer is an inorganic zinc silicate primer. The second coating layer is a polysiloxane. The third coating layer is a room temperature or high temperature vulcanizing silicone rubber. A silicone rubber sealant may be further applied to outer edge surfaces of the core.
