Drag Chain Cables
In equipment units that require back-and-forth movements, to prevent cable entanglement, wear, pulling, and scattering, cables are often placed into a cable drag chain. This setup protects the cable while allowing it to move with the drag chain. The high flexibility cables that can withstand such movements without wear and tear are called drag chain cables, often referred to as drag chain cables.
Drag chain cables are mainly used in:
- Industrial electronic systems
- Automatic generation lines
- Storage equipment
- Robots
- Fire systems
- Cranes
- CNC machine tools
- Metallurgical industry
Components of Drag Chain Cables:
- Tensile Centre
In the centre of the drag chain cable, depending on the number of cores, a true centre fill is used to support the structure. This prevents the strands from entering the centre area of the cable, protecting the overall structure. - Conductor Construction
The most flexible conductor, class 6, should be chosen. Generally, the thinner the conductor, the more flexible the cable is. - Core Insulation
The insulation inside the drag chain cable should not stick together. It needs to support each strand of the single-stranded wire. High-pressure moulding PVC or TPE materials are suitable for this application. - Shielding
The shielding of a drag chain cable should be tightly braided outside the inner sheath. Loose braiding reduces EMC protection and causes the shielding to fail. Tightly braided shields are also resistant to torsion. - Jacket Construction
Sheathing made of different modified materials serves various functions, such as UV-resistance, low-temperature-resistance, and oil-resistance. These sheaths share a common characteristic: high abrasion resistance and non-adhesiveness. The outer sheath must be highly flexible, supportive, and high-pressure moulded.
