Zusammenfassung: | The invention relates to a cable, and more particularly relates to a cable for an elevator. The cable for the elevator comprises a plurality of electric conductors and an insulator for covering the plurality of electric conductors. Each of the electric conductors includes a plurality of wire cores. Each wire core has an elastic insulated wire, and each of the elastic insulated wires is inserted in a central portion of the corresponding wire core in a passing through mode. Compared with cables in the prior art, since each of the wire cores in the electric conductors has one elastic insulated wire core, the strength in bending of each wire core is increased by the elastic insulated wire; while the cable is undergoing power output or signal transmission, the elastic insulated wires do not affect the conductive properties of the wire cores, so that the conductive portions, except the insulated wire cores, in the wire cores can be made through adoption of one kind of metal materials to ensure the consistency of th |
