Stranded conductors are made of multiple small strands, which group together to make up a single conductor. It is more flexible than a solid conductor, but less durable. Bunch stranding is a collection of strands twisted together in the same direction without regard to the geometric arrangement.

What does conductor strand mean?

Stranded conductors are composed of uninsulated “strands” of wire twisted together. The advantages of conductor stranding over a single strand of equal cross-section are increased flexibility and flex-fatigue life.

Why cable conductors are stranded?

Stranded wire is more flexible than solid wire of the same total cross-sectional area. Stranded wire is used when higher resistance to metal fatigue is required. ... At high frequencies, current travels near the surface of the wire because of the skin effect, resulting in increased power loss in the wire.
