Travelling cable for high-speed parallelly-connected elevators

The invention discloses a travelling cable for high-speed parallelly-connected elevators. The travelling cable comprises a cable core and an outer protective layer wrapped on the periphery of the cable core in squeezing mode, wherein the cross section of the outer protective layer is roughly oval, a first peripheral cylinder and a third pheripheral cylinder at two ends of a long axis direction of the oval cross section are respectively formed by two sections of converged minor-diameter arc cylinders, the converged portion of the two sections of converged arc cylinders form a concave, a second peripheral cylinder and a fourth peripheral cylinder at two ends in a short axis direction of the oval cross section are major diameter arc cylinders, and two ends of the major diameter arc cylinders are respectively in transition connection with a minor diameter arc cylinders. The travelling cable for high-speed parallelly-connected elevators has the advantages of being simple in structure, ingenious in design, capable of being effectively prevented from generating cross moving caused by wind power of a well.
