摘要： A non-contact power feeding coil of the present invention is a power feeding coil (3) that configures a non-contact power feeding system (1), the power feeding coil being provided with a coil (35) through which an AC current of a specific frequency flows, and a core (31) that forms a section of a circulating magnetic path, which is interlinked with the coil, in which in the coil, a wire (36) having an insulating covering (38) is wound around a conductor (37), and a covering thickness (Ti) of the insulating covering is set so that the influence of a proximity effect that occurs at the specific frequency between adjacent portions of the wire is a predetermined amount or less. According to this configuration, it is possible to freely adjust a separation distance between portions of the conductor by altering the covering thickness; and therefore, the occurrence of AC loss caused by a proximity effect is appropriately suppressed.

摘要： The present invention is intended, in view of eliminating the possibility of destroying the insulation of varnished coils, to address the weakening of the mechanical strength in the coil axis direction in time of short circuiting in the manufacturing process of coils without varnishing. The invention relates to an oil-filled transformer mounted with an iron core formed of an amorphous ribbon or a silicon steel sheet and a coil of which both high-voltage and low-voltage windings are formed of flat or round conductor lead wires wound around the iron core, in which a thermosetting resin-impregnated fiber is wound in the coil axis direction around the coil in a tap line wire lead part, and further the thermosetting resin-impregnated fiber is wound in the outermost layer of the coil. As the thermosetting resin-impregnated fiber, a glass binding tape made of epoxy resin is used.
