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
TRVV High-Flexibility Drag Chain Cable Product Details 1. Product Photos 2. Core Advantages 1. Ultra-strong flexibility, no cracking ✅ after a million bends Uses a special process of finely twisted soft conductors combined with high-elasticity insulation materials to give the cable "memory-level" flexibility! Rigorous laboratory testing proves it can withstand 10 million bending cycles, without core breaks or cracking! Whether it's the high-frequency swinging of industrial robots or the continuous back-and-forth of automated production lines, it can be easily handled, with stable transmission and no jams! 2. Wear-resistant and oil-proof, industrial oil contamination "immunity" 💪 The outer sheath is made of polyurethane (PUR) or specially modified PVC, offering high hardness and strong wear resistance, remaining intact even after 500 hours of friction on rough mechanical surfaces! Outstanding oil resistance, easily resisting corrosion from lubricating oil, hydraulic oil, and cutting fluids, ensuring consistent performance in high-oil environments such as machine tool processing and automotive manufacturing! 3. Strong tensile resistance and dual load-bearing 🏋️ transmission Built-in high-strength tensile fiber/Kevlar woven layer with tensile strength up to 10N/mm², equivalent to withstanding 1kg of tensile force per square millimeter! Effectively disperses stress in lifting and long-distance conveying scenarios, eliminating risks of deformation and breakage, ensuring stable power and signal transmission! 4. Environmental certification. Zero lead, zero cadmium added. Excellent insulation performance, operating temperature -40°C~90°C, stable operation whether in extremely cold storage or near high-temperature furnaces! 3. Application Scenarios Industrial Automation: CNC machine tools and intelligent warehouse drag chain connections for stable transmission of power and signals; 🤖 Robotics industry: Welding and spraying robot-specific cables adapted to high-frequency multi-angle movement; 🚜 Lifting and conveying: Cranes and conveyor belts provide mobile power supply to ensure flexible equipment lifting and lowering; 📦 Logistics packaging: Essential for automatic sorting and packaging machines to handle rapid mechanical operations! 4. Product Parameters Parameter Items Specific Parameters TRVV Conductor Material Multi-strand finely twisted oxygen-free copper wire, compliant with VDE 0295 Class 6 standard Insulation Material High-quality PVC/TPE with excellent insulation performance Outer Sheath Material Polyurethane (PUR) / Modified PVC Rated Voltage 300/500V Operating Temperature Range -40°C~90°C (PUR); -15°C~70°C (PVC) Minimum Bending Radius 7.5D (D is cable outer diameter) Flame Retardant Rating IEC 60332-1 Black/Gray, etc. (Supports customization) 5. Customization Service Optional Specifications: 0.14mm² - 50mm² wire diameter, 2 - 60 cores freely combinable; ✅ Length as desired: minimum order from 100 meters, precise cutting, zero waste; ✅ Special customization: shielding layer, torsional layer, cold-resistant/acid- and alkali-resistant outer sheath to meet personalized needs!
