stranded wire

Litz wires are electrical conductors consisting of a bundle of enamel-insulated individual wires. The individual wires are formed into a stranded wire by stranding

, or by strangling, which is the term used to describe the arbitrary bringing together of individual wires to form a bundle. Stranded wires are surrounded by a sheathing which forms the outer cable protection and insulates the stranded wire and protects it against mechanical stress, environmental influences and electrical contact.

Stranded wires can consist of a few and up to several hundred thin individual wires.

As they are much more flexible than rigid cables due to the many individual wires, they are not susceptible to bending and conductor breakage. In addition, the skin effect is not as strong as with solid conductors, because the total surface area of all individual stranded wires is much larger than that of a single solid conductor. For these reasons, stranded conductors are used wherever flexibility and a lower skin effect are required, such as in patch cables, antenna cables, microphone cables, loudspeaker cables and power cables.
