Tubular Stranding Machine – A Modern Solution for High-Efficiency Cable Stranding

 In today’s wire and cable manufacturing industry, production efficiency, stability, and flexibility are more important than ever. The Tubular Stranding Machine plays a key role in meeting these demands, especially for stranding copper, aluminum, aluminum alloy, and steel-cored aluminum conductors, as well as for cabling insulated wires.

Traditional tubular stranding machines usually rely on ground shaft transmission. In this structure, the cage rotation and traction are driven by a shared motor through complex mechanical components such as gearboxes, ground shafts, and angle boxes. While widely used in the past, this design brings several limitations. Open ground shaft transmission suffers from poor lubrication, dust contamination, and high noise levels. Gear shifting introduces mechanical gaps that can cause shocks, wear, and higher maintenance requirements. More importantly, the low cage rotation speed and fixed gearbox ratios restrict production speed and limit pitch adjustment, making it difficult to meet modern process requirements.

The Tubular Stranding Machine developed by LINT TOP addresses these issues through an advanced individual motor drive system. Each cage and capstan is powered by a separate motor, simplifying the mechanical structure and significantly reducing operating noise. This design not only improves transmission efficiency but also allows greater flexibility in speed and pitch control, supporting a wider range of stranding processes.

From a structural perspective, the cage bottom plate is integrally welded and machined in one setup using a CNC gantry boring and milling machine. This ensures high precision and excellent dynamic stability during high-speed operation. Before delivery, each cage undergoes dynamic balance testing with high-precision instruments, ensuring long service life and reliable performance.

The entire machine is managed by a PLC and touch screen interface, making operation intuitive and efficient. Multiple protection functions, including fault alarms, overload protection, air pressure monitoring, and automatic shutdown in case of wire breakage, further enhance operational safety.

With its modern drive concept, precise manufacturing, and intelligent control system, the Tubular Stranding Machine represents a reliable and future-ready solution for cable manufacturers aiming to improve productivity and product quality.
