Shanghai Suoqi Cable Co., Ltd. is deeply engaged in the field of special flexible cables. The following provides a professional interpretation of drag chain cables from three dimensions: material structure, performance advantages, and application scenarios.
1. Materials and Structural Parameters
PUR drag chain cables are specially designed for high-frequency reciprocating motion scenarios, using high-quality polyurethane (PUR) outer sheath material, featuring exceptional wear resistance, oil stain resistance, chemical corrosion resistance, and UV resistance. They are suitable for power transmission and signal control in drag chain systems such as industrial automation equipment, robots, and CNC machine tools, and are especially suitable for drag chain systems in complex and harsh indoor and outdoor environments, effectively ensuring long-term stable operation of equipment.
Product Design Advantages: Soft Mobility: High flexibility, resistant to repeated bending in drag chains, bending radius can reach 7.5 times the cable diameter, bending lifespan >5 million times, >10 million times; Excellent Durability: PUR outer jacket is wear-resistant and tear-resistant, providing superior durability compared to conventional material designs; Environmental Adaptability: Wide operating temperature range from -40℃ to 90℃ can be customized as needed, oil-resistant, acid and alkali-resistant, resistant to microbial corrosion, fully oil-proof; Personalized Customization: Power type, control type, data signal transmission type, etc., can be designed as required; single-core or multi-core structures can also be customized, unshielded, shielded, twisted-shielded, double-jacket structures, etc., designed according to requirements; widely applicable for different drag chain system installations.
Product Structure Design: Conductor: Ultrafine oxygen-free bare copper multi-strand finely twisted bundled cable conductor, compliant with VDE 0295/CLASS 6 conductor standards (tinned copper wire conductors can be designed as needed); Insulation: High-quality high-strength mixed elastomer materials/PE/TPE and other multiple materials can be selected as needed, meeting strict electrical performance of the cable; Core Identification: Color-coded cores or numeric coding for differentiation, with the ground core designed as yellow/green; Core Structure: Short-pitch optimized flexible anti-twist structure/grouped gap-filling/double-twisted pair structure designed as needed; Shielding Design: Tinned copper wire braided design for high-density shielding layer of the cable; Sheath Design: Special modified elastomeric nitrile inner sheath (if any, low-viscosity high-strength extrusion design); high-quality imported polyurethane (PUR) outer sheath; color options include black/gray/orange/green; High-Flexibility PUR Drag Chain Cable: PUR drag chain cables, with their high flexibility, oil resistance, wear resistance, and torsion resistance, are widely used in industrial scenarios requiring frequent reciprocal movement and complex conditions, and are widely applied in industrial robots and automation equipment, CNC machines and machining centers, logistics automation and sorting systems, and other applications with drag chain components. When selecting cables, it is necessary to fully consider cable movement speed, travel distance, bend radius, number of cores, and cross-sectional area. In special scenarios, the shielding layer (tinned copper wire braided shield) can be customized to enhance anti-interference capability. Multiple specifications and structures can be designed as needed, and friends in need are welcome to inquire for selection and purchase.
