Tensile Design of Drag Chain Cables for Rail Transit

The automated equipment drag chain system bends frequently and repeatedly; conventional cables can only withstand minor bends, leading to frequent core breakage and signal interruptions during long-term operation, resulting in a high failure rate for equipment. To address this pain point, Shanghai cable drag chain companies have made targeted optimizations from materials to processes: conductors comply with VDE 0295 CLASS 6 ultra-fine copper wire twisting, insulation uses specially made PVC/elastomer blends, outer sheaths are blended with PUR/TPU, and bending cycles ≥ 10 million times. In practical applications, the products have been recognized by customers in the mechanical and drag chain sectors for their wear resistance, tensile strength, and bending resistance.

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.

How to assess the bending lifespan of drag chain cables?

Measured by the number of bending cycles, high-quality drag chain cables can reach more than 8 million cycles. When selecting, it is necessary to match the drag chain's travel, speed, and bending radius.
