Abstract (en)
A tappable air core reactor in which the tappable portion has a conductor wound in the form of an open helical winding on the outer surface of a sleeve of electrically insulated material. The helical winding is partially embedded leaving exposed an outer surface to which a tap can be attached at any peripheral location around the reactor. The adjacent helices of the winding are separated by spacers and the conductor is a solid rod of selected cross-sectional profile in which the base portion is wedge-like. The cylinder, the valleys between the helically wound conductor and endrings at opposite ends of the winding is a solid rigid unit of glass roving impregnated and embedded in a set epoxy resin. <IMAGE>
