Our drag chain cable is designed specifically for the scenario of "non-stop back and forth movement". Through 7 core structural optimizations, it achieves 10 million bends without core breakage or faults, far exceeding the durability standards of conventional cables. It is perfectly adapted to high-frequency motion scenarios such as automation equipment, robotic arms, and conveyor lines.

Seven core structural designs to build a durable foundation

1. Solid tensile center: prevent strand displacement

The cable center adopts a solid dedicated tensile core (instead of filler or waste plastic), which matches the size accurately according to the number of core wires, tightly fills the cross gaps of the core wires, firmly fixes the stranded wire structure, prevents the stranded wire from floating or shifting during movement, and protects the integrity of the conductor from the source.

2. Optimize conductor structure: Balancing flexibility and tensile strength

Selecting a conductor combination of "ultra-fine copper wire+precise pitch" - the diameter of the copper wire has been verified through long-term experiments, ensuring ultimate flexibility (suitable for high-frequency bending) and avoiding winding problems caused by being too thin; Paired with optimized twisted joints, the conductor combines tensile and fatigue resistance, extending its service life.

3. High voltage formed insulation layer: non sticky, strong support

The insulation layer of the core wire is made of high-pressure formed PVC/TPE material, which has been verified through millions of meters of working conditions: on the one hand, it prevents adhesion between insulation layers (to avoid tearing when bent), and on the other hand, it can effectively support single stranded wires, resist compression and friction during bending, and protect the conductor from damage.

4. Sports adaptation twisted wire: bundled twisted wire is more stable

The stranded wire structure is designed around the tensile center and adopts the "optimal intersection pitch" to adapt to sports scenes; When the number of core wires is ≥ 12, the bundle twisting process is adopted to make the overall stress of the stranded wire more uniform, without stress concentration during bending, and to avoid local breakage.

5. Armor type inner sheath: locks the stranded wire without scattering

Replacing cheap wool or fillers, a one-piece extruded armor style inner sheath is used to tightly the stranded wire structure, forming a sturdy protective layer to prevent loose or misplaced stranded wires during movement and ensure the overall structural stability of the cable.

6. Tightly woven shielding layer: anti-interference+anti torsion

The shielding layer is tightly ped around the inner sheath with optimized weaving angles: on the one hand, it enhances the EMC electromagnetic shielding effect and resists external interference; On the other hand, the tightly woven structure also has anti torsion performance, avoiding the failure of the shielding layer during bending and twisting.

7. Multi functional outer sheath: wear-resistant, highly flexible, and adaptable to multiple scenarios

The outer sheath is made of improved formula materials, and functional options such as UV resistance, low temperature resistance, oil resistance, and cost optimization can be selected according to needs. However, all outer sheaths have three core characteristics:

High wear resistance: resist wear caused by drag and friction;

Non adhesive: Avoid dust and oil adhesion, maintain surface cleanliness;

High flexibility support: It combines high flexibility and toughness (suitable for bending) with structural support (resistant to compression), and is formed under high pressure with no risk of cracking.
