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 Polyurethane Drag Chain Cable Product Details 1. Product Photos 2. Core Advantages 1. PUR Polyurethane Outer Sheath, The All-Around Protective King High-performance PUR polyurethane material is used to make the outer sheath, combining multiple features such as wear resistance, oil resistance, hydrolysis resistance, weather resistance, and flame retardancy. The surface hardness reaches Shore 85A, and its wear resistance is three times that of ordinary PVC materials, making it resistant to high-frequency friction on rough mechanical surfaces; it maintains stable performance when exposed to industrial media such as lubricating oil, hydraulic oil, and coolant, as well as acidic, alkaline, and humid environments; it does not become brittle or deform in a wide temperature range of -40°C to 90°C, effectively handling various harsh working conditions.
2. Exceptional bending resistance and long service life Internally, it uses multi-strand finely twisted oxygen-free copper conductors combined with high-elasticity insulation materials, combined with a high-strength tensile fiber woven layer, giving the cable outstanding flexibility. Professionally tested, it can withstand over 12 million bending cycles, with a minimum bending radius of only 7.5D (D is the cable outer diameter). During frequent reciprocating motion of the drag chain system, the core remains unbroken and undamaged, significantly reducing replacement frequency and maintenance costs.
3. Efficient and Stable Transmission, Reliable Performance The conductor meets VDE 0295 Class 6 standards, with low resistance and low capacitance design, ensuring efficient and stable transmission of power and signals. Optional single-layer or double-layer shielding structure (aluminum foil shielding with tinned copper wire braid), with a shielding coverage of ≥90%, effectively resisting electromagnetic interference, suitable for high-demand data transmission scenarios such as industrial automation and robotics.
4. Environmental certification. Free from halogens, heavy metals, and other harmful substances. Insulation resistance ≥ 500MΩ/km, voltage resistance rating up to 300/500V, flame retardant rating compliant with IEC 60332-1 standard, ensuring safe and reliable use.
3. Application Scenarios Industrial Automation Production Lines: Used for drag chain connections on CNC machine tools and automated assembly lines, providing stable transmission of power and control signals in oily and dusty environments.
Automotive Manufacturing Workshop: Equipped with welding robots, painting robots, and other equipment, resistant to high temperatures, painting, and other complex environments, ensuring precise equipment operation.
Logistics and warehousing equipment: In stacker cranes and shuttle trailer chain systems, it meets the needs of high-frequency reciprocating motion and improves logistics transmission efficiency.
Port and mining machinery: Adapted to harsh outdoor environments, continuously and stably operating under conditions of humidity, dust, and extreme temperatures.
