What is Servo Cable
High flexible servo cable is a high‑flex special cable designed for servo motor drive systems. It integrates power lines, signal lines and shielding structure, widely used in automated production lines, machine tools, robotic equipment and motion‑control equipment. It can withstand frequent bending, twisting and reciprocating movement, ensuring stable power transmission and signal communication under continuous dynamic operation.
Ordinary common cables will suffer conductor breakage after frequent reciprocating movement. This high flexible servo cable adopts ultra‑fine stranding process to improve bending durability for continuous servo operation. The dense braided shielding blocks EMI noise on site, preventing signal distortion which may cause positioning deviation of servo axes.
Product Features

Custom Service
We support custom conductor cross‑section, core count, shielding structure, jacket material, cable length and special‑process requirements to match your on‑site equipment conditions. If you need high flexible servo cable with special specs for your servo drive project, feel free to send us your technical requirements.
Quality Assurance and Testing
Every high flexible servo cable leaving our factory passes a complete quality inspection process. We conduct high‑voltage spark tests, insulation resistance measurements, conductor continuity checks and sample bending‑cycle tests before shipment. Raw materials are verified batch by batch in our incoming quality control lab, ensuring consistent conductor purity and jacket material performance.
For customers requiring third‑party certification, we can provide UL and CE compliant variants with full test reports. Custom cable printing, color coding and reel packaging are also available to match your production line labeling standards.
FAQ for High Flexible Servo Cable
Q: What is the difference between servo cable and normal power cable?
Standard power cables lack ultra‑fine tinned‑copper stranding and dense braided shielding. Under continuous dynamic reciprocation inside cable chains, ordinary cables suffer core breakage and signal drift quickly. High flexible servo cables are specially engineered for cyclic‑bending scenarios, maintaining stable power delivery and anti‑interference performance over millions of bending cycles.
Q: Can your servo cable work in cable chain?
Yes. Our high‑flex servo cables are optimized for cable chain applications. The tinned fine‑stranded conductor together with PUR outer sheath delivers outstanding cyclic bending performance for day‑to‑day moving operations.
It can withstand millions‑times bending cycles for dynamic motion applications.
