Drag chain cables are mainly used in industrial electronic systems, automatic generation lines, warehousing equipment, robots, fire protection systems, cranes, CNC machine tools, and metallurgical industries.
Introduction:
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. This type of high flexibility specialized cable that can move back and forth with the drag chain but is not easily worn out is called a drag chain cable, which is also commonly referred to as a drag cable or tank chain cable.
Composition of drag chain cable:
1.Tensile center
At the center of the cable, there should be a true centerline filling as much as possible based on 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 structure of the stranded wire and prevent the stranded wire from drifting into 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.Core insulation
The insulation materials inside the cable must not stick to each other. And the insulation layer also needs to support each single strand of wire. Therefore, its reliability can only be proved in the application of high-pressure formed PVC or TPE materials in millions of meters of cable of drag chain.
4.Stranded wire
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 inner sheath of the armor shaped extrusion molding 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 protective ability of EMC 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.
