Litz wire employs a stranded wire with individually insulated conductors (forming a bundle). Each thin conductor is less than a skin-depth, so an individual strand does not suffer an appreciable skin effect loss. The strands must be insulated from each other—otherwise all the wires in the bundle would short together, behave like a single large wire, and still have skin effect problems. Furthermore, the strands cannot occupy the same radial position in the bundle over long distances: the electromagnetic effects that cause the skin effect would still disrupt conduction. The weaving or twisting pattern of the wires in the bundle is designed so that the individual strands are on the outside of the bundle for a distance (where the EM field changes are smaller and the strand sees low resistance), and are inside for a distance (where the EM field changes are the strongest and the resistance is higher). If each strand has a comparable impedance, current is distributed equally among every strand within the cable. This allows the interior of the litz wire to contribute to the overall conductivity of the bundle.Flat or rectangular, multiple stranded magnet wire.Strands are film insulated and stranded together in a rectangular configuration permitting each wire to lie on the surface of the conductor.The small wires are then twisted into a bundle such that each wire spends the same amount of time in the middle and on the outside of the bundle. This creates multiple electrically identical routes for the electric to take, reducing the apparent resistance.
