High Speed Planetary Stranding Machine Is Designed For High-Volume Production Of Multi-Core Cables

The High Speed Planetary Stranding Machine is designed for high-volume production of multi-core cables, such as control, power, and data cables. It's a key machine for applications requiring dense, high-quality stranding, including charging piles, photovoltaics, and robotics.

Working Principle & Key Features

Planetary Cage Action: Multiple reels are mounted on a rotating planetary cage. As the cage orbits a central axis, each reel simultaneously rotates on its own, twisting the wires together. This "sun-and-planet" gear system can be configured for back-twisting to produce round, compact, and concentric cable cores.

High Speed & Productivity:

Modern machines are engineered for high rotational speeds and line speeds, significantly boosting output while maintaining quality.

Uniform Tension Control:

Equipped with individual tension systems (magnetic brakes, hysteresis, or dancer arms) managed by PLCs to ensure consistent lay length and prevent conductor ovality or surface defects.

Versatile Configurations:

Available in various sizes (e.g., 315, 400, 500, 630) with different reel capacities (6, 12, 18, 24, 30) to accommodate a wide range of wire diameters and final cable sizes.

Integrated Line Components: A complete production line typically includes:

Central or side pay-off stands

Planetary stranding cage with back-twist

Die holder and pre-twisting device

Taping/armoring heads

Capstan and haul-off

Take-up with traversing system

Electrical control cabinet with HMI

Typical Applications

Control & Power Cables: For robotic, automation, and industrial control cables requiring dense stranding.

New Energy Cables: Widely used for EV charging piles, photovoltaic (PV) cables, and wind turbine cables.

Data & Communication Cables: Suitable for premise cables and composite optical-electrical cables.

Specialty Cables: For high-flex cables, elevator cables, and medical cables where quality and consistency are critical.

Engineering & Support Focus

Process & Line Layout: Defining conductor size, lay length, and line speed. Providing GA drawings for foundations, power (typically 3×380V, 50Hz), and safety clearances.

Commissioning & Training: On-site installation, threading, and startup. Training operators on operation, tension adjustment, and basic troubleshooting.

Remote & Field Support: Diagnosing issues remotely via phone or video. Supplying spare parts like bearings, belts, and sensors. Providing on-site service for major failures or upgrades.

Maintenance & Optimization: Developing preventive maintenance schedules and advising on control system upgrades or data integration for Industry 4.0.

Engineering Tips

Balance the Cage: Ensure bobbin loading is balanced to minimize vibration and bearing wear at high speeds.

Robust Tension Control: Use high-quality, calibrated tension systems. For fine-stranded conductors, consider closed-loop magnetic or servo tension for better results.

Foundation & Alignment: A rigid foundation is crucial. Precise alignment of the cage, capstan, and take-up is essential to prevent vibration and extend component life.

Leverage Simulation: For custom or high-speed designs, use multi-body dynamics software (like RecurDyn) to model loads, optimize the drive system, and reduce trial-and-error
