When equipment units need to move back and forth, sheathed drag chain cables are often put into the cable drag chain to prevent the cables from being entangled, worn, pulled out, and scattered. This protects the cables and allows the cables to be towed. The chain can move back and forth. This kind of highly flexible special cable that can follow the drag chain to move back and forth without being easy to wear is called drag chain cable. It can also be called
drag cable

tank chain cable.
.
Drag chain cables are mainly used in industrial electronic systems, automatic production lines, warehousing equipment, robots, fire protection systems, cranes, CNC machine tools and metallurgical industries.
The composition of conventional sheathed drag chain cables
Pull center
In the center of the cable, there should be a true centerline filling as much as possible according to the number of cores and the space of the intersection area of each core. (Instead of filling it with garbage core wires made of some filler or waste plastic as is usually the case) This method can effectively protect the stranded wire structure and prevent the stranded wires from straying to the central area of the cable.
Body 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, the cable will become entangled. A series of long-term experiments provided the best combination of diameter, length and pitch for a single wire to provide the best tensile strength.
Wire Insulation
The insulating materials within the cable must not stick to each other. And the insulation layer also needs to support each single strand of wire. Therefore, its reliability has only been proven during applications in millions of meters of cables made of high-pressure formed or materials that can be used in energy chains.
Wire
The stranded wire structure must be wound around a stable tensile center at an optimal interleaving pitch. However, due to the application of insulating materials, the stranded wire structure should be designed according to the moving state, starting from the core wire, so it should be bundled and twisted.
Sheath
An armor-style extruded inner sheath replaces cheap wool materials, fillers or accessory fillers. This method ensures that the stranded wire structure does not become scattered.
Shielding
Weave the shielding layer tightly outside the inner sheath with an optimized braiding angle. Loose braiding will reduce the protection capability and the shielding layer will soon fail due to shielding breakage. The tightly woven shield is also torsion resistant.
Sheath
Outer sheaths made of different improved materials have different functions, including anti-function, low-temperature resistance, oil resistance and cost optimization. But all these outer sheaths have one thing in common, they are highly abrasion resistant and will not stick to anything. The outer sheath must be highly flexible but also have a supporting function, and of course it should be high pressure molded
