Abstract

A suspension wire structure comprises a conductive wire, a plurality of supporting stranded wires and a protective layer. The conductive wire has a first strand made of a first material. The plurality of supporting stranded wires surround the conductive wire, and each of the supporting stranded wires has a plurality of supporting strands made of a second material. The protective layer covers the surface of the conductive wire and is located between the conductive wire and the plurality of supporting stranded wires. The plurality of supporting stranded wires and the protective layer are conductive, and the protective layer is made of a third material. The first material, the second material and the third material are different from each other.
