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.
Product original reference: Highly flexible PUR drag chain cable (oil-resistant, corrosion-resistant, bend-resistant)
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: Highly flexible, capable of enduring repeated bending and movement in drag chains, bending radius up to 7.5 times the cable diameter, bending lifespan > 6 million cycles; Excellent Durability: PUR outer sheath is wear-resistant and tear-resistant. Compared with conventional materials, the cable offers superior durability; Environmental Adaptability: Wide operating temperature range from -40°C to 90°C, customizable as needed, oil-resistant, acid and alkali-resistant, resistant to microbial erosion, fully oil-proof; Personalized Customization: Can be designed for power, control, and data signal transmission as needed; single-core or multi-core structures can also be customized, including unshielded, shielded, twisted double-shielded, double-sheath structures; widely applicable for drag chain systems under different requirements.
Product Structure Design: Conductor: Ultra-fine oxygen-free bare copper stranded bundled cable conductor, meeting VDE 0295/CLASS 6 conductor standards (tinned copper wire conductors can be designed on demand); Insulation: High-quality high-strength hybrid elastomer material / 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 codes, with ground core designed as yellow/green; Core Structure: Short pitch optimized flexible anti-twist structure / grouped gap filling / pair-twisted structure designed as needed; Shielding Design: Tinned copper wire braided design for high-density cable shielding layer; Jacket Design: Special modified elastomeric nitrile material inner jacket (if any, low-viscosity high-strength extrusion design); high-quality polyurethane (PUR) outer jacket; available in black/gray/orange/green, etc.; Highly Flexible PUR Drag Chain Cable: PUR drag chain cable, with characteristics of high flexibility, oil and wear resistance, and torsion resistance, is widely used in industrial scenarios that require frequent reciprocating movement and complex working conditions. It is widely applied in industrial robots and automation equipment, CNC machine tools and machining centers, logistics automation and sorting systems, and various situations with drag chain components. When selecting cables, it is necessary to fully consider the cable movement speed, travel distance, bending radius, number of cores, and cross-sectional area. In special scenarios, the shielding layer (tinned copper wire braided shielding) can be customized to enhance anti-interference capability. Multiple specifications and structures can be designed as needed. Friends in need are welcome to consult and purchase.
