Cable for elevator

The invention relates to a cable and particularly relates to a cable for an elevator. The cable comprises a plurality of conductors and a plurality of insulators for covering the conductor, wherein zipper fastener tapes are arranged on the two sides of each insulator respectively; all the insulators are detachably connected through the zipper fastener tapes; and after the insulators are connected with one another, all zipper fastener teeth of the zipper fastener tapes on any one insulator are completely engaged with all the zipper fastener teeth of the zipper fastener tapes of the adjacent insulator. Compared with the prior art, the insulators can be directly matched with each other through the zipper fastener tapes so that the two insulators are detachably connected; a worker can increase the quantity of the conductors in the whole cable in the future according to the quantity of devices, which is actually increased, in a lift car, so that the weight of the whole cable can be effectively controlled and the p
