The company is committed to providing cost-effective products and personalized cable solutions to global customers, earning high market recognition and a good reputation.
2. Product Structure (1) Conductor The conductor is made of high-purity oxygen-free copper, finely stranded from multiple ultra-fine annealed copper wires, and conforms to Class 6 of DIN VDE 0295 (or IEC 60288) standards. This structure gives the cable extremely high flexibility, easily coping with complex bending actions, while ensuring excellent electrical conductivity, effectively reducing resistance, minimizing energy transmission loss, and ensuring that power is delivered to equipment stably and efficiently.
(2) Insulation Layer: A specially customized elastomer composite insulating material is selected, which has excellent tensile properties. It can not only provide reliable insulation protection for the conductor and prevent current leakage, but also withstand the stress generated during frequent movement and bending of the cable, maintaining good electrical performance.
(3) Shielding Layer (Some Models) To address complex electromagnetic interference working environments, some cables are equipped with shielding layers. They use soft-tinned copper wire mesh for braided shielding, with a weaving density of over 85%, effectively blocking external electromagnetic interference, ensuring the accuracy and stability of internal signal transmission, and meeting the demands of equipment with stringent signal quality requirements, such as automation control systems and precision instruments.
(4) Sheath The outer sheath uses specially blended, highly elastomer, eco-friendly materials, such as premium polyurethane (PUR) or special PVC. PUR sheathed cables have excellent oil and wear resistance, can withstand oil contamination and frequent friction, and are suitable for machine tool processing, automotive manufacturing, and other oil-stained and wear-prone scenarios; Special PVC sheaths ensure a certain degree of flexibility and wear resistance while also offering good weather resistance, maintaining good physical properties over a wide temperature range from -40°C to 80°C, ensuring stable operation of cables in various environments.
3. Product Performance Advantages (1) Ultra-high flexibility and bending resistance The cable design fully considers the demands of high-frequency movement, with an extremely small bending radius—as low as 6 to 8 times the cable's outer diameter (or even less for some high-performance models), enabling frequent and large bends in confined spaces, perfectly adapting to the complex motion trajectories of drag chain systems. Through laboratory simulations of over 10 million bending tests, the cable structure remains intact, performance indicators show no significant decline, greatly reducing faults caused by cable bending fatigue and significantly improving equipment operational reliability and stability.
(2) Strong tensile resistance Internally adding high-strength reinforcing cores, such as aramid fiber or galvanized steel wire ropes, enhances the cable's overall tensile strength. In practical applications, even when equipment starts and stops quickly, accelerates rapidly, or endures strong external pulling, the cable maintains structural stability without breakage, ensuring continuous power and signal transmission and providing reliable support for smooth equipment operation.
(3) Excellent anti-interference capability Cables equipped with shielding layers perform excellently in environments with strong electromagnetic interference. They effectively block electromagnetic radiation generated by the equipment's own electrical system and surrounding electronic devices, ensuring stable signal transmission and preventing issues such as inaccurate operation or data transmission errors caused by interference. It is especially suitable for fields sensitive to electromagnetic environments, such as automated production lines and medical equipment.
(4) Excellent environmental adaptability, oil and corrosion resistance: The outer sheath material has a strong resistance to oil, acids, alkalis, and other chemical substances, allowing it to work stably in corrosive environments such as chemical and food processing industries, thereby extending the service life of the cable.
Excellent weather resistance: Able to withstand temperatures as low as -40°C and high temperatures as low as -40°C and high temperatures up to 80°C. Whether in the cold northern winters or hot industrial workshops, it maintains excellent flexibility and electrical performance, functioning properly.
