An insulated winding 3, suitable for a magnetic component, comprises at least one turn 8 formed from a single flat sheet of conductive material. The said at least one turn 8 being provided with an insulating coating formed using an insulating powder. A single flat sheet of copper may be etched, cut or stamped in a pattern which can be folded to form a multiple turn winding. The insulating powder may be an epoxy resin or a ceramic powder which is placed in an electrostatic fluidised bed into which the winding is dipped. The powder coating is then cured to provide the required insulation coating. Uncoated portions 7, 23 of the winding 3 may be winding connection terminals. One or more coatings may be applied to obtain the desired insulation level. Earthed screens 5, 6 may be placed between windings as a safety isolation mechanism. Also disclosed is a method of manufacturing the above winding. The above winding may provide a high conductor to insulation ratio for windings passing through a window of transformer core. |
