摘要： Tap covers and projections for an electrical device are provided. The tap projections have bosses or taps raised from a surface of the tap projection and encapsulated with a resin except for an outer surface of the bosses or taps. The tap projections may have a channel or recess between individual bosses or taps to prevent degradation of the insulation between the respective adjacent bosses or taps. When a tap cover is provided, it is pushed on or bolted to the tap projection. The tap cover may be provided for an individual tap or an entire tap projection and may be formed of a resin or an elastomeric material. The tap cover has a first generally planar surface and a second generally annular surface having a circumferentially-extending groove on an inside surface. The circumferentially-extending groove is located slightly beneath the second generally annular surface. The groove of the tap cover is designed to fully engage with a raised lip of a tap projection or individual tap of a transformer. Another embodiment of the tap cover has openings to receive epoxy-headed bolts that are used to connect the tap cover to the tap projection through the tap connectors.

摘要翻译： 提供电气设备的抽头盖和突起。 龙头突起具有从龙头突起的表面凸起的凸起或水龙头，并且除了凸起或水龙头的外表面之外用树脂封装。 龙头突起可以在单独的凸台或水龙头之间具有通道或凹槽，以防止相应的相邻凸台或水龙头之间的绝缘的劣化。 当提供水龙头盖时，将其按压或螺栓连接到水龙头突起。 抽头盖可以设置用于单个抽头或整个抽头突出部，并且可以由树脂或弹性体材料形成。 龙头盖具有第一大体上平坦的表面和在内表面上具有周向延伸的槽的第二大体呈环形的表面。 周向延伸的凹槽位于第二大体环形表面的稍微下方。 分接盖的凹槽被设计成完全与变压器的抽头突起或单独抽头的凸起的唇部接合。 龙头盖的另一实施例具有用于接收环氧树脂头螺栓的开口，其用于通过龙头连接器将龙头盖连接到龙头突起。

摘要： A composite electrical insulation material is comprised of first, second and third layers. The first and third layers are glass fiber mat and the second layer is a thin film material. The first and third layers are bonded to the second layer using a thin resin solution. The insulation is used in electrical machines such as transformers, generators, and motors. The insulation serves as a high/low barrier, high voltage conductor wrap, and low voltage sheet insulation in transformers. In generators and motors, the insulation serves as wrap for conductor windings and wedge insulation for stator and rotor assemblies.

摘要： 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.
