Flexible Cable

I. Definition and Core Features  
Flexible cables are a type of special cable designed for frequent movement, bending, or twisting applications. Their core characteristics involve the use of multi-stranded fine copper wire conductors and elastomeric insulation/sheathing materials, which ensure excellent mechanical flexibility and fatigue resistance while maintaining electrical performance.  

Core Features:  
Dynamic Installation: Suitable for continuous or intermittent motion equipment  
High Bending Lifespan: Capable of millions of bending cycles (e.g., drag chain cables)  
Torsion Resistance: Some models can withstand torsional stress of ±180° to ±720°/meter  
Environmental Adaptability: Oil-resistant, wear-resistant, and weather-resistant  

II. Main Types and Application Scenarios  
Typical Industries:  
Industrial Automation: Robotic arms, conveyor belts, inspection equipment  
Logistics and Warehousing: Stackers, sorting lines, lifts  
Energy Equipment: Wind turbine pitch systems, solar trackers  
Special Vehicles: Cable reels for mining vehicles, fire truck ladders  
Stage and Film: Moving lights 

III. Key Control Points in Production Process  
Conductor Stranding Process:  
Uses Class 5 or Class 6 conductors (IEC 60228)  
Optimized lay ratio to prevent conductor deformation during stretching  
Matching of stranding direction with cabling direction  

Insulation and Sheathing Materials:  
PUR (Polyurethane): High wear resistance, oil resistance, and tear resistance  
TPE/TPU (Thermoplastic Elastomer): Good flexibility, environmentally friendly  
Special PVC: Economical bending-resistant solution  

Shielding and Anti-Interference Design:  
Tinned copper wire braided shielding (coverage ≥85%)  
Aluminum foil + drain wire composite shielding  
Paired/star quad structure to reduce crosstalk  

Specialized Cabling Equipment:  
Anti-twist stranding equipment to prevent internal stress  
Constant tension payout systems  
Online eccentricity detection instruments
