Abstract
The invention discloses a wearable, high-temperature-resistant, tension-resistant and environmentally-friendly cable of a railway locomotive. The cable is characterized in that a plurality of conductors are all composed of sixth thinned copper bundles by twisting and then re-twisting, wherein the re-twisting pitch ratio does not exceed 14 times; insulating layers wrap the plurality of conductors to form insulating cores, wherein the insulating cores are mutually twisted to form a bundle which serves as a cable core; one or a plurality of steel wires are positioned in the cable core; an isolating layer and a sheath layer sequentially wrap the cable core, wherein the isolating layer comprises a polyester belt; a thermoplastic polyurethane elastomer sheath layer is extruded and formed at the outside of the isolating layer. The cable is simple in structure; polyether-ether-ketone materials are used for insulating; the cable is resistant to oil, high temperature, high-temperature steam and radiation, high in flexibility, small in smoke, free of halogen, and difficult to be fired; one or the plurality of steel wires are positioned in the cable core, so that the tension resistance is improved, and the service life of the cable can be prolonged to some extent.
