Tinsel wire is a conductor made by winding a layer of ultra-thin metal foil or multiple layers of metal foil around a soft textile fiber core. The specifications produced are very fine and flexible, with a low specific gravity. Compared with traditional solid wires, its bending strength and tensile strength have been greatly improved, and it has better oxidation resistance and is easier to weld. With imported raw materials and special processes, the product has a long service life, good wear resistance and corrosion resistance under high temperature and high pressure. The multi-layer copper foil design and multi-strand twisted design significantly reduce the conductor resistance, and the breaking load and swing performance are also greatly improved.
Tinsel wire is composed of two materials, with a metal foil surface and a fiber core inside. Common metal foil materials include bare copper foil, tin-plated copper foil, nickel-plated copper foil, silver-plated copper foil, tin-copper alloy copper foil, iron-copper alloy copper foil, silver-copper alloy copper foil, etc. Common fiber materials include nylon, polyester, aramid, liquid crystal fiber, heat-resistant cotton yarn, glass fiber, etc.
The outer diameter of a single Tinsel Wire can be as small as 0.04mm to 0.40mm, with either a single-layer or multi-layer copper foil structure. It can be twisted into Tinsel Wire strands or mixed with copper wires, mainly to increase the bending strength of the conductor.
