Introduction to PUR Drag Chain Cable with Double Sheath and Shielding Structure
The double-sheath, shielded PUR drag chain cable is specially designed for drag chain applications with high mobility speeds and acceleration. Its tinned copper braided shielding layer gives the cable excellent electromagnetic interference resistance, effectively protecting against external electromagnetic signal interference and ensuring stable and accurate signal transmission. The high-quality imported polyurethane (PUR) outer sheath features outstanding wear resistance, oil resistance, acid and alkali corrosion resistance, resistance to high and low temperature variations, and mechanical fatigue resistance, allowing it to easily handle various complex and harsh operating environments. Whether in humid and dusty locations or under alternating extreme temperature conditions, it can operate stably. For these reasons, this cable is widely used in frequently moved and bend-resistant applications, including power supply, control connections, and data signal transmission feedback.
Product Design Description
This dual-sheath, shielded PUR drag chain cable is crafted with meticulous attention to material selection and structural design, suitable for the drag chain requirements in a variety of complex and demanding scenarios such as ports, docks, industrial robots, and chemical enterprises:
Conductor: Uses an ultra-fine oxygen-free bare copper wire multi-strand precision twisted bundle design, meeting VDE 0295/CLASS 6 conductor standards, with excellent conductivity and flexibility. At the same time, tinned copper wire conductors can be selected according to actual needs to further enhance the cable's corrosion resistance in special environments.
Insulation: Selecting high-quality, high-strength hybrid elastomer materials, PE, TPE, and other materials, customizing the cable insulation layer as needed, strictly meeting the electrical performance requirements of the cable, and ensuring the cable operates safely and stably under different voltage and current conditions.
Core wire: The core wire uses a short-pitch optimized flexible anti-twist structure, combined with grouped gap filling or twisted pair design to meet diverse connection application needs, effectively maintaining the stability of the internal core wire, significantly enhancing cable durability and service life.
Inner sheath: Made with specially modified elastomer material, formed through a low-viscosity strong extrusion process, tightly wrapping the core wire to provide reliable internal support and protection for the cable.
Shielding layer: Uses tin-plated copper wire braiding technology to create a shielding mesh, providing comprehensive protection against external electromagnetic interference, ensuring precise and reliable signal transmission in complex electromagnetic environments.
Outer Sheath: Made with high-quality imported polyurethane PUR material, available in black, gray, orange, green, and other colors. While meeting aesthetic needs, its excellent physical and chemical properties provide comprehensive protection for the cable's internal structure.
