Coil Cables By J S R Global Enterprises

Coiled cords and cables have a spring-like form that allows them to stretch and bend with minimal stress on the wire. They can be extended to a length several times greater than their at-rest length, but return to their original length when released.   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.
