As cable manufacturers continue to pursue higher productivity, better stability, and safer operation, upgrading core stranding equipment has become a practical necessity. The High Speed Tubular Stranding Machine is an optimized solution designed specifically for 7-core copper stranded wire, aluminum stranded wire, mild steel wire, and ACSR production, based on the classic 630/1+6 structure.
Compared with conventional tubular stranders, this upgraded model delivers a significant leap in performance. With a maximum operating speed of up to 700 rpm, its production efficiency is approximately 1.5 times higher than that of standard machines, while maintaining smoother and more stable operation with reduced noise levels. This makes it especially suitable for manufacturers seeking continuous, high-speed production.
A key highlight of the machine is its tailor-made pneumatic pintle type pay-off system. Whether the bobbin is full or nearly empty, the pay-off damping tension remains stable. Even during sudden stops under high-speed conditions, the wire is unlikely to loosen or break. From cylinder braking to complete stop, the passive pay-off speed stays well synchronized with the traction speed, ensuring consistent stranding quality.
The three-section cylinder design further enhances long-term stability. Each section is supported by large short cylindrical roller bearings of the same specification and model (NBI brand), allowing the machine to operate reliably 24 hours a day under high-speed conditions. This uniform bearing configuration not only improves accuracy but also extends service life and maintenance intervals.
Safety and operator convenience are equally emphasized. The fully enclosed sound-insulated protective cover features a three-layer structure and pneumatic flip-up doors with built-in LED lighting. Electrical monitoring ensures the machine cannot start unless all doors are properly closed, greatly improving operational safety. External wiring, automatic window positioning after stop, and quick bobbin clamping and release significantly reduce labor intensity and bobbin change time.
Additionally, the built-in wire break stopping device effectively prevents cylinder flywheel accidents, while the intelligent information system enables remote monitoring and proactive maintenance alerts. This “nanny-style” service capability allows users to maintain optimal equipment performance with confidence.
Overall, the High Speed Tubular Stranding Machine represents a reliable and future-oriented upgrade for modern stranding lines, combining speed, stability, safety, and intelligent operation into one integrated solution.
