Abstract

A coil device (10) includes a primary winding of multistranded wire that has been wound around a supporting structure (12), a conductive core (34, 36) positioned both inside and outside the primary winding, a first insulating layer (18) around the primary winding, and at least one securing member (40) that secures the core, supporting structure and primary winding as a coil device unit. The device may also include a secondary winding of wire, such as multistranded wire. The device may be used as a self-adjusting transformer or choke in electrical applications.
