Drag Chain Cables: The Complete Guide to High-Flex Industrial Cables | YUEDAO Manufacturing
What Are Drag Chain Cables?
Drag chain cables (also known as tow or energy chain cables) are ultra-flexible cables designed for high-frequency reciprocating motion, capable of withstanding millions of bends without wear or fracture. With the global industrial automation market growing at an 8.5% CAGR through 2030 (Grand View Research), demand for drag chain cables as critical components continues to surge.

FAQ Section :
Q: How do drag chain cables differ from standard cables?
A: Drag chain cables use 7 core technologies (e.g., fine-strand conductors, armored jackets) to survive millions of bends vs. standard cables (≤50k cycles).
Q: How to calculate minimum bending radius?
A: Formula: Bending radius = Cable diameter × 7.5. Example: 10mm cable requires ≥75mm radius.
Q: Temperature limits for drag chain cables?
A: Standard: -40°C to +105°C. High-temp versions (silicone jackets) available up to +150°C.
