A drag chain cable is a highly flexible specialized cable that can move back and forth with the drag chain without being easily worn out. It is also commonly referred to as a drag cable or tank chain cable. In situations where the equipment unit needs to move back and forth, in order to prevent cable entanglement, wear, detachment, hanging, and scattering, the cable is often placed in the cable drag chain to form protection for the cable, and the cable can also move back and forth with the drag chain

Composition 1. The tensile center is filled with a true centerline at the center of the cable according to the number of cores and the space in the intersection area of each core wire (instead of filling with garbage core wires made of some filling materials or waste plastic as usual). This method can effectively protect the stranded wire structure and prevent the stranded wire from floating to the center area of the cable. 2. Conductor structure cables should choose the most flexible conductor. Generally speaking, the thinner the conductor, the better the flexibility of the cable. However, if the conductor is too thin, it can cause cable entanglement. A series of long-term experiments have provided the optimal shielding combination of diameter, length, and pitch for a single wire, which has the best tensile strength. 3. The insulation materials inside the core insulated cable should not stick to each other. And the insulation layer also needs to support each single strand of wire. Therefore, only high-pressure formed PVC or TPE materials can be used in the application process of millions of meters of cable drag chains to prove their reliability. 4. The stranded wire structure must be wound around a stable tensile center at the optimal intersection pitch. However, due to the application of insulation materials, the stranded wire structure should be designed according to the motion state, starting from 12 core wires, as it should be twisted in bundles. 5. The armor shaped inner sheath replaces cheap wool materials, fillers, or accessory fillers. This method can ensure that the stranded wire structure is not scattered. 6. The shielding layer is tightly woven outside the inner sheath using an optimized weaving angle. Loose woven tape will reduce the EMC protection ability and the shielding layer will quickly fail due to the breakage of the shielding. The tightly woven shielding layer also has the effect of resisting torsion. 7. The outer sheath is made of different improved materials and has different functions, including UV resistance, low temperature resistance, oil resistance, and cost optimization. But all of these outer sheaths have one thing in common: high wear resistance and won't stick anything. The outer sheath must be highly flexible but also have support function, and of course it should be high-pressure formed
