What is drag chain cable?
Drag chain cable is a kind of high-flexible special cable that can move back and forth with the drag chain and is not easy to wear. It can also be called drag cable or tank chain cable.
Introduction to drag chain cables
When the equipment unit needs to be moved back and forth, in order to prevent the cables from entanglement, wear, pull-off, hanging and scattered. Often put the cable into the cable drag chain to protect the cable, and the cable can also move back and forth with the drag chain.
Structure composition of towline cable
1. The tensile center of the drag chain cable
In the center of the cable, according to the number of cores and the space between each core wire, there is a true centerline filling as much as possible. This method can effectively protect the structure of the stranded wire and prevent the stranded wire from drifting to the central area of the cable.
2. Conductor structure of drag chain cable
The cable should choose the most flexible conductor. Generally speaking, the thinner the conductor, the better the flexibility of the cable, but if the conductor is too thin, the cable entanglement will occur. A series of long-term experiments have provided the best diameter, length and pitch shield combination of a single wire, which has the best tensile strength.
3. Core insulation of drag chain cable
The insulating materials in the cable must not stick to each other. Moreover, the insulating layer also needs to support each single strand of wire. Therefore, only the high-pressure molded PVC or TPE material can be used in the application process of millions of meters of cables in the drag chain to prove its reliability.
4. Stranded wire of drag chain cable
The stranded wire structure must be wound around a stable tensile center with the best cross-pitch. However, due to the application of insulating materials, the stranded wire structure should be designed according to the state of motion, starting with 12 core wires, because the stranding method should be used.
5. Inner sheath of drag chain cable
The armor-style extruded inner sheath replaces cheap wool materials, fillers or accessory fillers. This method can ensure that the stranded wire structure will not be scattered.
6. Shielding of drag chain cable
The shielding layer is tightly braided outside the inner sheath with an optimized braiding angle. The loose braid will reduce the EMC protection ability and the shielding layer will soon fail due to the breakage of the shielding. The tightly woven shield layer also has the function of resisting torsion.
7. Outer sheath of drag chain cable
The outer sheath made of different improved materials has different functions, including UV resistance, low temperature resistance, oil resistance and cost optimization. But all these outer sheaths have one thing in common, high abrasion resistance, 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 forming.
