[0002] Drum cables are mainly used in bucket wheel excavators, drum reels, transport machinery, large cranes and conveyors with retractable systems. The drum cables are retracted and extended following the guidance of the towing shaft or other similar devices. With the improvement of the level of modern mechanical equipment, the requirements for the corresponding cables are getting higher and higher. Various electrical and monitoring and control equipment are also installed on these large mechanical equipment, which requires power cables, control cables, etc. to be installed on the equipment for power transmission and electrical control. Since these cables are generally installed on the equipment and released as the equipment moves, the space on the equipment is limited. If they are laid separately, not only do they need to reserve a separate position, but the difficulty and cost of laying cables are further increased due to the separate laying of different types of cables.
[0003] Large machinery such as bucket wheel excavators, winches, large cranes and conveyors are mainly used in special environments such as factories, granaries, docks, steel mills, large thermal power plants and mines. The machines have high operating efficiency and are frequently used for moving back and forth. In such working conditions, the cables need to be able to transmit electric energy stably, and also require the cables to be cold-resistant, tensile-resistant, wear-resistant, corrosion-resistant, soft, oil-proof, and have high-strength mechanical load-bearing capacity to adapt to various special working environments indoors and outdoors.
