CLASS 130 - 240 0.08 MM * 24 STRANDS HIGH FREQUENCY LITZ WRE FINE STRANDED SILK COVERED USTC WIRE
Litz wire employs a stranded wire with individually insulated conductors (forming abundle). 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 singlelarge wire, and still have skin effectproblems.Furthermore, the strands cannot occupy the same radial position in the bundleover 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 conductivityof the bundle.
