Super Flexible PUR-Sheathed Copper Shielded (EMC) Drag Chain Cable – High-Performance Solution for Continuous Motion Industrial Applications

Designed for the most demanding dynamic operating environments, our Super Flexible PUR-Sheathed Copper Shielded (EMC) Drag Chain Cable sets a new standard for reliability, durability, and electromagnetic compatibility in industrial motion systems. Engineered with premium materials and precision manufacturing, this cable is specifically optimized to withstand millions of bending cycles, resist harsh industrial conditions, and ensure stable signal/power transmission – making it the ideal choice for drag chain applications across diverse industries.

Core Features & Technical Advantages

1. Exceptional Flexibility for Continuous Motion

• Ultra-High Flex Life: Constructed with fine-stranded oxygen-free copper conductors (class 6/7 stranding) and a flexible insulation structure, the cable supports up to 10 million bending cycles (tested per IEC 60228/EN 50290) in drag chain systems, eliminating premature fatigue or breakage even in high-speed reciprocating motion.

• Torsion & Bending Resistance: The optimized conductor lay length and flexible stranding design enable tight bending radii (down to 5× cable outer diameter), adapting seamlessly to complex drag chain trajectories in robotic arms, linear modules, and automated production lines.

2. Durable PUR Sheath for Harsh Environments

• Premium PUR Material: The outer sheath is made of high-quality Polyurethane (PUR) – renowned for excellent wear resistance, oil resistance, chemical resistance, and hydrolysis resistance. It withstands abrasion from drag chain guides, exposure to industrial oils, solvents, and harsh weather conditions (temperature range: -40℃ to +90℃).

• Mechanical Protection: PUR’s inherent toughness provides superior impact resistance and tear resistance, preventing damage from mechanical stress, friction, and heavy-duty industrial use. It is also flame-retardant (compliant with IEC 60332-1) for enhanced safety.

3. Copper Shielding for EMC Compliance

• Reliable Electromagnetic Shielding: Equipped with a dense copper braid shield (coverage ≥ 85%) or copper foil + braid double shield, the cable effectively blocks electromagnetic interference (EMI) and radio frequency interference (RFI). It ensures EMC compliance with EN 55032/EN 55011 standards, protecting sensitive signal transmission from external interference and preventing internal signals from interfering with other equipment.

• Stable Signal/Power Transmission: The shielding structure minimizes signal attenuation and crosstalk, guaranteeing consistent performance for both power supply (up to 450/750V) and data transmission (e.g., encoder signals, control signals) in high-interference industrial environments.

4. Industrial-Grade Reliability & Customization

• Wide Operating Temperature: Functions reliably in extreme temperatures from -40℃ (low-temperature resistance for cold storage or outdoor applications) to +90℃ (high-temperature stability for industrial equipment with heat generation).

• Customizable Specifications: Available in various conductor sizes (AWG 26-10), core counts (2-60 cores), and shielding options (copper braid, foil + braid, tinned copper shield). We offer tailored solutions such as halogen-free variants (compliant with IEC 60754-2), waterproof designs (IP67-rated), or flame-retardant grades for specific industry requirements.

• Easy Installation & Maintenance: The lightweight and flexible design simplifies cable routing in drag chains, while the PUR sheath’s smooth surface reduces friction with chain links, extending the service life of both the cable and the drag chain system.

Application Fields (B2B Industry Focus)
