Cable used for elevator

The invention relates to a cable and especially relates to a cable used for an elevator. The cable comprises a plurality of conductors and a plurality of insulators covering the conductors respectively. A female adhesive tape with a clamping groove and a male adhesive tape with a projection part are respectively arranged on two sides of each insulator, and the insulators can be detachably connected through the female and male adhesive tapes. After the insulators are mutually connected, the projection part of the male adhesive tape of any insulator is totally inserted into the clamping groove in the female adhesive tape on the adjacent insulator. Compared with the prior art, the detachable connection of two insulators are directly realized by interaction between the female and male adhesive tapes, and workers are enabled to increase the number of the conductors in the cable according to the practically increased number of devices in an elevator car in the future, so that the weight of the whole cable is effect
