Stranded wire - a type of wire which is made from a bunch of many strands (thinner wires), twisted together to make an overall larger effective cross-sectional area.1) Very fine strands can also be referred to as filaments, especially in superconducting stranded cables.2)
Strands are used for improving mechanical flexibility of stranded wire, the thinner the strand the more flexible the whole wire.
In an ordinary stranded wire, the strands are made from bare copper or aluminium, so the strands are electrically connected to each other throughout the length of the wire.
In Litz wire the strands are electrically isolated from each other, for example by a coat of enamel. Typically, the strands in Litz wires are made from readily available enamelled wire.
