Composite cable

The invention belongs to the technical field of cables, and particularly relates to a composite cable which comprises a cable tube, and a group of annularly and uniformly distributed partition plates are fixedly mounted on the surface of the cable tube; the outer skin is connected with the outer ends of the two adjacent partition plates respectively; the cavities are formed among the two adjacent partition plates, the cable tube and the outer skin, and the number of the cavities is multiple; the electric wire is arranged in the cavity; the conductive effect of the wire is prevented from being reduced due to heat accumulation, so that the cable is convenient to use; at the same time, a traditional cable sheath is generally in an annular integrated shape, so that when a single wire is spontaneously combusted or the sheath is locally combusted due to external interference, fire spreads along the integrated sheath, and the whole sheath is combusted, and the sheath is divided into a plurality of strips by the sepa
