500MΩ
300V

The drag chain system of automated equipment bends frequently and repeatedly; conventional cables can only withstand minor bends, and long-term operation leads to core wire breakage and signal interruptions, resulting in a high failure rate of equipment. Shanghai Suo Qi drag chain cables are specially designed for these working conditions, with conductors complying with VDE 0295 CLASS 6 ultra-fine copper wire stranding, insulation made from specially made PVC/elastomer blends, PUR/TPU blended outer sheath, and bending resistance ≥ 10 million cycles. The cables feature wear resistance, bending resistance, and high flexibility, and are widely used in drag chains, automation, production lines, and other fields. Shanghai Suo Qi Cable is sold directly from the source factory, with multiple core counts and specifications customized on demand, ample stock, nationwide shipping, and a consultation hotline 13311756197.

Product Features

High flexibility and bending resistance, guaranteed lifespan after millions of cycles The internal conductor uses multi-strand finely twisted oxygen-free copper wire, combined with highly elastic TPE insulation and tensile fiber braiding layer, giving the cable outstanding flexibility. Tested rigorously in the laboratory, it can withstand over 12 million bending cycles, with a minimum bending radius of 7.5D (D is the cable outer diameter). During high-frequency reciprocating motion of the drag chain system, the core and wire are not broken, meeting the long-term dynamic usage needs of automated equipment.

Category 5 standard, stable high-speed transmission. Strictly adhering to Category 5 cable standards, the four-pair twisted pair structure effectively reduces crosstalk, with transmission speeds as high as 1000Mbps, transmission distance of 100 meters, and support for 10/100/1000 Base-T Ethernet protocols. Paired with a dual-layer shielding design (aluminum foil shielding, tin-plated copper wire braiding, shielding coverage ≥95%), effectively resists electromagnetic interference, ensures zero delay and zero packet loss for data transmission, suitable for industrial automation control, monitoring systems, and other scenarios requiring extremely high network stability.

Environmental certification. No halogens or heavy metals added, safe and pollution-free. Insulation resistance ≥ 500MΩ/km, voltage resistance up to 300V, flame retardant rating meets IEC 60332-1 standard, safe and worry-free to use.

3. Application Scenarios Industrial Automation Production Lines: Connecting PLC controllers, industrial switches, sensors, and other devices to achieve real-time data transmission and monitoring of production lines.

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 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.
