The key to selecting drag chain cables is to consider the working conditions. Shanghai Suoqi drag chain cables use twisted pair conductors with individual shielding and overall shielding (aluminum foil and tinned copper braid), with a polyurethane jacket. They are suitable for high-frequency reciprocating bend conditions in drag chains and tank chains, featuring high flexibility, oil resistance, and the core advantages of polyurethane. They can be widely used in drag chains, automation, production lines, and other scenarios. Direct sales from the source manufacturer, with stable delivery times.

Product Features

2. Product Features High flexibility and bending resistance The conductor uses multi-strand finely twisted oxygen-free copper wire, strictly adhering to the VDE 0295 CLASS 6 standard. The single wire diameter is extremely fine and treated with a special twisting process to give the cable excellent flexibility. Laboratory tests show it can withstand over 5 million bending cycles. Under complex conditions, such as the frequent reciprocating motion of automated production chains, it can maintain structural integrity without core breakage or cracking, ensuring long-term stable power and signal transmission.

Cold and heat resistant: The working temperature range is wide. For fixed installations, it is -50°C to 90°C, and for mobile installations, it is -30°C to 90°C. Some specially customized models can withstand short-term temperatures up to 125°C. Whether in the high-heat steel smelting workshop, the low-temperature refrigerated cold chain warehouse, or outdoor work environments with significant seasonal temperature differences, this cable can operate stably and adapt to different temperature challenges.

Flame Retardant and Environmental Protection: Flame retardant rating reaches V0, complies with IEC 60332-1 fire protection standards, effectively preventing fire from spreading along cables in emergencies such as fires, ensuring the safety of personnel and equipment. No added lead, cadmium, or other harmful substances, safe and pollution-free, aligning with current green industrial development concepts.

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 needs, making it convenient to use in different installation spaces and electrical connection requirements. The core wire insulation comes in a variety of colors, allowing for colored wires; for cables with a higher number of cores, black wires with white numeric labels can also be used, making them clear and easy to distinguish. In addition, cables with more than 3 cores come with a standard yellow/green dual-color grounding wire to ensure electrical safety.

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.
