The drag chain system of automated equipment bends at high frequency and repeats; conventional cables can only withstand minor bends, and during long-term operation, the core wires are prone to breakage and signal interruptions, resulting in a high failure rate for equipment. Shanghai Suo Qi Cable Drag Chain Cable is specially designed for these working conditions, with conductors complying with VDE 0295 CLASS 6 ultra-fine copper wire stranding, insulation made from specially made PVC/elastomer blends, PUR/TPU blend, and bending cycle resistance ≥ 10 million cycles. The cable features wear resistance, oil resistance, polyurethane resistance, and is widely used in automation, CNC technology, robotics, and other fields. Shanghai Suo Qi Cable is sold directly from the source factory, with multiple cores and specifications customized on demand, with ample stock and nationwide shipping.

Product Design Advantages

Flexible mobility: highly flexible, resistant to drag chain cyclic bending and movement, bending radius up to 7.5 times the cable diameter, bending lifespan of > 5 million cycles and > 10 million cycles; Excellent durability:P UR outer sheath is wear-resistant and tear-resistant, offering superior durability compared to conventional material designs; Environmental adaptability: wide temperature range from -40°C to 90°C customizable as needed, oil-resistant, acid- and alkali-resistant, microbial corrosion resistance, fully oil-resistant performance; Personalized customization: power-driven, control-type, data signal transmission type, etc.; Single-core or multi-core structures can also be designed as needed, including unshielded, shielded, twisted-pair shielded, double-sheathed structures, etc.; Widely installed and applied to drag chain systems with different requirements.

Product structure design

Conductor: Ultra-fine oxygen-free bare copper strands twisted and bundled for the cable conductor, compliant with VDE 0295/CLASS 6 conductor standards (tinned copper wire conductors can be designed on demand); Insulation: High-quality high-strength hybrid elastomer materials / PE / TPE or other materials selectable as needed to meet strict electrical performance of the cable; Core Identification: Colored wires or numeric coding for distinction, ground wire designed in yellow/green; Core Structure: Flexibly designed anti-twist structure with short pitch / grouped gap filling / twisted pair structure as required; Shielding Design: Tinned copper wire braided high-density shielding layer; Sheath Design: Special modified elastomer nitrile inner sheath (if any, low-viscosity strong extrusion design); High-quality imported polyurethane (PUR) outer sheath; available in black / gray / orange / green and other colors; Highly Flexible PUR Drag Chain Cable: PUR drag chain cable, due to its high flexibility, oil and wear resistance, and anti-torsion properties, is widely used in industrial scenarios requiring frequent reciprocating movement and complex working conditions, commonly applied in industrial robots and automation equipment, CNC machines and machining centers, logistics automation and sorting systems, and other systems with drag chain components. When selecting the cable, the cable moving speed, travel distance, bending radius, number of cores, and cross-sectional area should be fully considered. In special scenarios, a shielding layer (tinned copper wire braided shield) can be customized to enhance anti-interference capability. Multiple specifications and structures can be designed as needed. Friends with needs are welcome to consult and purchase.

Frequently Asked Questions

Why do drag chain cables use CLASS 6 conductors?

CLASS 6 is an ultra-fine multi-stranded finely twisted conductor with much greater flexibility than ordinary conductors, able to withstand tens of millions of bends without easily breaking the core.

How to assess the bending lifespan of drag chain cables?

Measured by the number of bending cycles, high-quality drag chain cables can reach more than 8 million cycles. When selecting, it is necessary to match the drag chain's travel, speed, and bending radius.
