Automated equipment drag chain systems experience high-frequency reciprocating bending. Conventional cables can only withstand slight bending, causing core wires 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 is recognized by customers in the drag chain, automation, and production line sectors for its high flexibility, oil resistance, and shielding performance. Customization according to drawings and direct shipment from stock are supported. For details, please contact 13311756197.

Product Features

2. Outstanding Product Features Exceptional high flexibility and bending resistance Conductor advantages: The conductor uses multi-strand finely twisted oxygen-free copper wire, strictly adhering to VDE 0295 CLASS 6 standard. The single wire diameter is extremely fine, and after special twisting processing, the cable is endowed with extraordinary flexibility. In laboratory simulation tests, it can withstand up to 8 million cycles of bending. Even under complex industrial conditions, such as frequent reciprocating motion in automated production line drag chain systems, it maintains structural integrity without issues such as core breakage or cracking, ensuring long-term stable transmission of power and signals.

Wide environmental adaptability: Cold and high temperature resistance: The operating temperature range is extremely broad. When fixed installation, it can stably run within a temperature range of -50°C ~ 90°C, and can also adapt to -30°C ~ 90°C during mobile installation. Some specially customized models can withstand short-term temperatures up to 125°C. Whether in scorching steel smelting workshops, cold chain logistics warehouses with low temperatures, or outdoor workplaces with significant seasonal temperature differences, this cable can handle it with ease and operate normally, fully demonstrating its powerful temperature adaptability.

Flame Retardant and Environmental Protection: Flame retardant rating reaches V0, strictly complying with IEC 60332-1 fire protection standards. In emergencies such as fires, the cable can quickly and automatically block the spread of fire, buying valuable time for evacuation and firefighting, and effectively ensuring the safety of personnel and equipment. Moreover, No harmful substances such as lead or cadmium are added, ensuring safety and pollution, in line with current trends and requirements of green industry development.

Flexible structural design Core wire arrangement and identification: Core wires can be flexibly arranged in a straight line or plum blossom pattern according to actual usage needs to suit different installation spaces and electrical connection requirements. Core wire insulation comes in a wide variety of colors, allowing for the choice of colored core wires; For cables with a large number of cores, black wire bodies with white numeric numbers are used, making them clear and easy to distinguish, making installation and maintenance convenient. Additionally, cables with 3 or more cores come with standard yellow/green dual-color grounding wires, further ensuring electrical safety.

3. Key Product Parameters Rated Voltage: When the conductor cross-sectional area is less than 0.5mm², the rated voltage is 300/300V; when the conductor cross-sectional area is greater than or equal to 0.5mm², the rated voltage is 300/500V.

Frequently Asked Questions

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.

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.
