The central supporting layer comprises a steel wire and a fiber wire which is wound on the surface of the steel wire. The electric power conductive wire area has a three-layer structure which is formed in a way that insulating wire cores are wound outside the central supporting layer in turn. Specifications and winding directions of a first wire core, a second wire core and a third wire core are different from each other. The electric power conductive wire area is separated from the central supporting layer and the communication conductive wire area via insulating braiding sleeves.
