Coil Cables - Copper Conductors, Polyurethane Jacket, Heat-set Spring Design | Flexible, Durable, Ideal For Stretch Applications

Construction

Coil cords, as they are sometimes called, consist of straight sections followed by curly sections. To achieve their spring-like form, the curly sections of metal wire are wound around a mandrel. Typically, the wires geometry is round; however, rectangular or even oval cross-sections are sometimes used. After these coiled sections are wound, the cable is jacketed (typically a polymer) and then heat-set into that shape.

Materials

Like other wire and cable products, coiled cables have a conducting material inside and an insulating or jacketing material outside. Coil cords may also be foil shielded, and use heat-laminated Mylar for heat shielding. Metals such as copper, aluminum, and tinned copper are used as conductors. Polyvinyl chloride (PVC) and polypropylene (PP) may be used to insulate and jacket the coiled cord. For resistance to mineral oils, cutting fluids, and abrasions, polyurethane (PU) jacketing is often used.
