Polypropylene ropes are disposed between the first conductors and the second conductors and are disposed at an outer side of the second conductors to enable an interior of the cable to be filled plump and uniformly when an insulating cable core is cabled so that compactness of the cable is ensured. The two first conductors and the two second conductors are coated successively by a halogen-free low-smoke flame-retarding polyolefin inner liner layer, two galvanized steel strip armoring layers and an irradiation-crosslinking halogen-free low-smoke flame-retarding polyolefin outer protective layer. The halogen-free low-smoke flame-retarding polyolefin inner liner layer is wrapped by the two galvanized steel strip armoring layers at intervals. The cable is excellent in electrical conductivity and can satisfy different current-carrying capability. The irradiation-crosslinking halogen-free low-smoke flame-retarding polyolefin insulating layer and the irradiation-crosslinking halogen-free low-smoke flame-retarding polyolefin outer protective layer are good in stability, heat-resistant performance and flame retardant performance, are free of halogen and low in smoke, is harmless to environment and is good in environmental tolerance.
