The application range of drag chain cables has gradually expanded with the continuous advancement of automation technology, but when choosing wires and cables for drag chains, should you choose cables dedicated to drag chains or ordinary flexible cables? Let's look at what a drag chain cable is and its structure.
Drag chain cable definition
When equipment units must be moved back and forth to protect the cables from being entangled, worn, pulled off, hooked, and scattered, the cables are usually placed in cable drag chains. This design not only protects the cable but also allows the cable to move with the movement of the drag chain. This highly flexible special cable that can move back and forth with the drag chain and is resistant to wear is called a drag chain cable.
Drag chain cable composition
Conductor structure
The most flexible conductor for drag chain cables should be selected. Usually, the thinner the conductor, the softer the cable itself will be; however, the core wire composed of too thin a conductor is easy to break, and the cable will also become entangled. The single conductor provided by Jiutai Special Cable has the best diameter and the best tensile strength.
Core wire insulation
The insulation materials in the cable cannot stick to each other, and the insulation layer needs to support each wire. Therefore, only high-pressure molded special flexible PVC and imported PUR materials can be used for millions of meters of cables towed in motion.
Tensile cable formation
A real center wire fills the space in the cable's center based on the number of cores and the intersection area of each core wire. This method can protect the stranded wire structure and prevent the stranded wires from escaping to the cable—central region.
Stranded wire structure
The stranded wires must be wound around a stable tensile center at an optimal intersecting pitch, and the structure must also be designed according to the motion state.
Copper wire shielding
Optimize the braiding angle to braid the shielding layer on the cable tightly. The tight braiding layer can resist strong electronic interference and resist torsion.
Cable sheath
The outer sheath must be highly flexible and have supporting functions: wear-resistant, oil-resistant, bending-resistant, high/low-temperature-resistant, waterproof, anti-corrosion, etc.
In cable design, every aspect is crucial. The conductors and materials of wires and cables used in drag chains have been screened at all levels, and the process is continuously improved. The conductors, materials, and processes complement each other and jointly determine the quality of drag chain cables.
