Litz wire is a type of cable used in electronics to carry alternating current. The wire is designed to reduce the skin effect and proximity effect losses in conductors used at frequencies up to about 1 MHz.^[1] It consists of many thin wire strands, individually insulated and twisted or woven together, following one of several carefully prescribed patterns^[2]often involving several levels (groups of twisted wires are twisted together, etc.). The result of these winding patterns is to equalize the proportion of the overall length over which each strand is at the outside of the conductor, an effect not achieved with simple twisted-strand hookup wire.
