The invention provides a lift cable with a steel wire bearing cable core and relates to the technical field of cables. The lift cable comprises a steel wire, an inner sheath, a plurality of threads of bundled naked copper wire conductors, a core wire insulating layer, a non-woven layer, a loading layer and an outer sheath, wherein the inner sheath is arranged outside the steel wire and the plurality of threads of the bundled naked copper wire conductors with the core wire insulating layer are stranded into a cable by taking a steel wire loading core cable as the center; the non-woven layer covers the plurality of threads of the bundled naked copper wire conductors, the outer sheath is arranged outside the non-woven layer, and the loading layer is arranged between the non-woven layer and the outer sheath. The lift cable adopts the steel wire bearing cable core and a textile protective braided layer, so that the lift cable can be suspended and used in a long length and the service life of the cable is prolonged.
Description
technical field [0001] The invention relates to the technical field of cables, in particular to an elevator cable with a steel wire carrying cable core. Background technique [0002] The elevator is an indispensable means of transportation in high-rise buildings. It must move up and down frequently, and the cables that provide the working power for the elevator must also move up and down with it. For this reason, due to the unreasonable design of the traditional cable, due to its poor tensile resistance during the repeated lifting process, it may break after a long period of regular lifting movement, resulting in power failure or interruption of other related functions. . Contents of the invention [0003] The object of the present invention is to provide an elevator cable with a steel wire bearing core, which adopts a steel wire bearing core and a textile protective braiding layer, which can be hung in a large length and prolongs the service life of the cable.
