40AWG 0.08mm * 24 Strands Mylar Wire PET Coat Copper Litz Wire For
Motor
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.
