Automated equipment drag chain systems experience high-frequency reciprocating bending. Conventional cables can only withstand slight bending, causing core wires to break and signals to be interrupted during long-term operation, resulting in a high equipment failure rate. To address this issue, Shanghai Suoqi Drag Chain Cables have been specifically optimized in both materials and processes: the conductors use VDE 0295 CLASS 6 ultra-fine copper wire strands, the insulation is made of a special PVC/elastomer compound, and the outer sheath is a PUR/TPU blend, with a bending cycle resistance of ≥10 million times. In actual applications, the product has been recognized by customers in the fields of automation, CNC, and robotics for its wear resistance, oil resistance, and polyurethane performance. Customization according to drawings and direct shipment from stock are supported. For details, please contact 13311756197.

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

What is the purpose of the shielding layer in a drag chain cable?

Tin-plated copper braided aluminum foil composite shielding suppresses electromagnetic interference, ensuring stable transmission of servo and encoder signals at high speeds.

What should be considered when selecting drag chain cables?

Travel, speed, acceleration, bending radius, and oil resistance must be provided, with margins reserved for the most demanding conditions to avoid early failure.
