This case study explains how Rolan Cable developed a high-flex shielded drag-chain cable for multi-axis industrial robot arms used in automotive and 3C electronics manufacturing, collaborative robots and material-handling systems. The cable solution was designed for repeated bending, torsional movement and stable power and signal transmission in demanding automation environments.

Customer Pain Points

Ordinary industrial cables cannot adapt to 3D multi-angle torsion, frequent bending and cyclic swing of robot arm joints, internal core wire fracture within 2-3 months
Common cable outer sheath easy to wear, crack and aging under long-term high-frequency robot operation, oil mist and industrial dust corrosion
Unstable signal transmission, sudden robot arm pause & equipment shutdown, huge production downtime loss
Imported robot arm matching cables with ultra-high procurement cost, long delivery cycle

Our Customized Cable Solution

We adopt robot-arm dedicated ultra-high flexible stranded structure, torsion-resistant PUR outer sheath, tinned oxygen-free copper conductor and anti-interference shielding design, specially developed for robotic arm dynamic working condition:

Ultra-flex stranding design: Fine strand bare/tinned copper core, bear ±180° per meter arm torsion, 30 million+ bending cycle service life
Abrasion & oil resistant PUR jacket: Anti-aging, anti-oil, anti-dust, fit workshop harsh industrial environment
Shielded hybrid cable structure: avoid robot servo signal interference
Small bending radius compact design: Fit narrow robot arm internal installation space, perfect for cobot & 6-axis robot dress pack
Custom wire gauge, core number and length, support direct plug-and-play wiring for robot arm

Project Application Scope

Equipment: 6-axis industrial robot arm, collaborative robot, handling robot, welding robotic arm
Usage: Robot arm joint wiring, drag chain built-in cable, servo encoder cable, robot external mobile cable
Industry: New energy automobile manufacturing, 3C electronic assembly, automated packaging workshop

Final Project Effect & Client Benefits

After 18 months of continuous on-site operation, our high flex robot arm drag chain cable keeps zero failure, zero core breakage and zero signal loss.

Reduce robot arm cable replacement frequency by 90%, cut equipment maintenance downtime greatly
35% lower purchase cost than original imported supporting robot cables
Stable anti-interference performance, realize long-term continuous unmanned operation of robotic arm
Stable bulk delivery & one-stop customized service, support customer mass robot equipment production
