Automated equipment drag chain systems undergo high-frequency repetitive bending. Conventional cables can only withstand slight bending; with long-term operation, the cores easily break, leading to signal interruptions and high equipment failure rates. Shanghai Suoqi drag chain cables are specifically designed for such conditions. The conductors comply with VDE 0295 CLASS 6 ultra-fine copper wire strands, the insulation uses a specially formulated PVC/elastomer blend, and the outer sheath is a PUR/TPU composite, capable of withstanding ≥10 million bending cycles. The cables feature high flexibility, wear resistance, and tensile strength, and are widely used in automation, robotics, and drag chain applications. Shanghai Suoqi cables are sold directly from the source factory, can be customized with multiple cores and specifications as needed, are well-stocked for nationwide delivery, and consultation can be reached at 13311756197.

Product Features

Tensile design: The cable is cleverly designed internally, incorporating high-strength central tensile fibers such as aramid yarn fibers, or in special applications with a free suspension length of >80m, high-strength galvanized soft steel wire ropes are inserted. These tensile components effectively disperse tensile stress, allowing the cable to withstand tensile forces up to 12N/mm². Under the strong pulling forces generated by rapid robot movement and start-stop operations, it will not break or deform, greatly extending service life.

Wide temperature adaptability: The working temperature range is extremely broad. When installed in a fixed position, it can operate stably in the temperature range of -50°C to 90°C, and when installed for mobile use, it can adapt to temperatures from -30°C to 90°C. For some specially customized models, short-term temperature resistance can even reach 125°C. Whether it is the high-temperature environment of a steel smelting workshop, the low-temperature environment of a cold chain logistics warehouse, or outdoor work sites with significant seasonal temperature variations, this cable can handle it with ease, operate normally, and fully demonstrate its strong temperature adaptability.

Flame Retardant and Environmentally Friendly: The flame retardant rating reaches V0, strictly complying with the IEC 60332-1 fire safety standard. In the event of a fire or other emergency, the cable can quickly prevent the spread of flames on its own, buying valuable time for personnel evacuation and firefighting, effectively ensuring the safety of people and equipment. In addition, it does not contain harmful substances such as lead or cadmium, making it safe and non-polluting, in line with the current trends and requirements of green industrial development.

Double-layer shielding (optional): In precision robot control scenarios with extremely high electromagnetic compatibility requirements, such as high-precision assembly robots in electronic chip manufacturing workshops, double-layer shielding structures with tin-plated copper wire braided shielding and aluminum foil wrapping can be provided. This double-layer shielding design further enhances anti-interference capability, can withstand more complex and high-intensity electromagnetic interference, ensures zero error in signal transmission, and guarantees high precision and stability in robot execution.

Flexible structural design Core wire arrangement and identification: The core wires can be arranged in a straight line or in a staggered pattern according to actual usage needs, to accommodate different robotic internal space layouts and electrical connection requirements. The insulation colors of the core wires are diverse; for wires less than 0.5mm², there are multiple color options such as brown, black, blue, red, purple, white, and orange. For wires of 0.5mm² or larger, black wires with white numerical markings are used, making them clear and easy to distinguish, which facilitates installation and maintenance. In addition, cables with more than 3 cores feature a standard yellow/green dual-color grounding wire, further ensuring electrical safety.

Frequently Asked Questions

What should be considered when selecting drag chain cables?

Travel, speed, acceleration, bending radius, and oil resistance must be provided, with margins reserved for the most demanding conditions to avoid early failure.

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.
