Tensile Design of Drag Chain Cables for Port Terminals

The drag chain system of automated equipment undergoes high-frequency repetitive bending. Conventional cables can only withstand slight bending, causing the cores to break and signals to be interrupted during long-term operation, resulting in a high equipment failure rate. To address this issue, Shanghai Suoqi Drag Chain Cables have been specifically optimized in both materials and processes: the conductors use VDE 0295 CLASS 6 ultra-fine copper wire strands, the insulation is made of a special PVC/elastomer blend, and the outer sheath is a PUR/TPU blend, with a bending cycle resistance of ≥10 million times. In actual applications, the product has been recognized by customers in the fields of automation, drag chains, and production lines for its tensile strength, Kevlar reinforcement, and wear resistance. Customization according to drawings and direct delivery from stock are supported. For details, please contact 13311756197.

Product Features

1. Precision Structure, Crafting Extraordinary Quality High-Strength Tensile Core: The center of the cable is equipped with a specially designed tensile-resistant component, typically made of materials such as Kevlar fibers or high-strength steel wires. Like a sturdy backbone, it provides the cable with powerful tensile resistance, effectively preventing internal structural damage during long-distance dragging and rapid start-stop operations of equipment, ensuring the stability of power and signal transmission.

Multi-strand finely stranded conductor: Made with high-purity oxygen-free copper wire, processed through multi-strand stranding, the single wire diameter is extremely fine and uniform, greatly enhancing cable flexibility, allowing it to easily handle frequent bending and twisting environments, reducing the risk of conductor breakage caused by bending, and ensuring unobstructed current and signals.

Double-layer shielding protection: For complex industrial environments with severe electromagnetic interference, drag chain cables are equipped with a double-layer shielding structure. The inner layer uses tin-plated copper wire braided shielding to effectively block low-frequency interference; The outer layer is covered with aluminum foil shielding, forming strong barriers against high-frequency interference, ensuring the cable transmission signals are pure and stable, unaffected by external electromagnetic noise.

3. Wide Application, Supporting Industrial Upgrades Industrial Automation Production Lines: On the automated production lines in industries such as automobile manufacturing, electronics, and food and beverage, drag chain cables provide stable power and signal transmission for various automated equipment, such as handling robots, assembly robots, and conveyor lines, ensuring efficient and precise operation of the production lines, improving production efficiency, and reducing production costs.

Frequently Asked Questions

What is the purpose of the shielding layer in a drag chain cable?

Tin-plated copper braided aluminum foil composite shielding suppresses electromagnetic interference, ensuring stable transmission of servo and encoder signals at high speeds.

Why do drag chain cables use CLASS 6 conductors?

CLASS 6 is an ultra-fine multi-stranded finely twisted conductor with much greater flexibility than ordinary conductors, able to withstand tens of millions of bends without easily breaking the core.
