At present, six types of copper conductor structures are commonly adopted for conductors of drag chain (mobile) flat cables produced by enterprises at home and abroad, or on the basis, fibers such as Sprapa, aramid fibers, copper foil wires and the like and special-alloy materials are added during conductor stranding so as to enhance the toughness and tensile strength of the conductors and achieve the purpose of keeping continuous transmission of electric power (signals) without core breakage under the action of external forces such as repeated bending and twisting of the conductors. The traditional stranding technology of the mobile cable conductor cannot meet the ever-increasing mobile requirement of an artificial intelligence machine, particularly on a robot (human) device which moves at high frequency. The upper limit of the service life of the conductor is generally about 1500 ten thousand times. This limits the lifetime of the corresponding device.
