High-toughness stainless-steel interlocked armored aluminum-alloy cable

The utility model discloses a high-toughness stainless-steel interlocked armored aluminum-alloy cable comprising alloy conductors and insulated layers. The alloy conductors are wound to form at least five cable cores. The center of each cable core is provided with a copper conductive core. An aluminum-alloy cable is wound around each copper conductive core. The outer side of each cable core is coated with an insulated layer. A polytetrafluoroethylene tough guide rod is arranged between the adjacent cable cores. The outer side of the insulated layers of the cable cores is coated with a wrapping inner liner layer. The wrapping inner liner layer wraps the tough guide rod in a gap among the at least five cable cores. A gap between the tough guide rod and the cable cores is filled with a flame-retardant filling material. The outer side of the steel band armored layer is coated with a cross-linked polyethylene insulated layer. The outer side of the cross-linked polyethylene insulated layer is coated with a flame-retardant protective sleeve. The stainless-steel interlocked armored part used by the high-toughness stainless-steel interlocked armored aluminum-alloy cable is simple in structure, and has a good armoring protection effect, an anti-radiation protection effect, and a good heat-insulating property. The cable cores in composite structure enable the toughness of the cable to be better than that of a conventional aluminum alloy cable and enable the impact strength of the cable to be increased by over 12 percent than that of conventional aluminum alloy cable while cost is not increased.
