The drag chain cable is a high-flexibility special cable which can move back and forth along with the drag chain and is not easy to wear, and is called a drag chain cable, and can be generally called a drag cable, and the tank chain cable is arranged on the occasion that equipment units need to move back and forth, and is usually placed into the cable drag chain in order to prevent the cable from being entangled, worn, pulled off, hung and scattered, so that the cable is protected, and can also move back and forth along with the drag chain, and the most flexible conductor is selected for the cable, generally speaking, the thinner conductor is, the better the flexibility of the cable is, but the thinner conductor is, and the cable winding phenomenon can be generated. A series of long-term experiments provided the optimum diameter, length and nodal shielding combination for a single wire, which had the optimum resistance to pulling. The insulation materials within the cable cannot stick to each other. But the insulation also needs to support each individual strand of wire. The reliability of the PVC or TPE material is therefore only proven during applications where it is possible to use it in multi-million cables for drag chains, the stranded structure having to be wound around a stable tension-resistant center with an optimum joint pitch. However, due to the use of the insulating material, the stranded wire structure should be designed in a motion state, starting from 12 core wires, and thus a bundle stranding method is adopted.

The cable is damaged or the conductor is dislocated due to the fact that the cable is damaged or affected by multiple times of movement, bending and straightening when the cable is used daily, the service life of the cable is greatly shortened, a large amount of manpower and material resources are needed for later-stage replacement and maintenance, and the production efficiency of the machine is reduced.
