Planetary Stranding Machine: Where Geometry Meets High-Performance Power Transmission
Core Structure and Working Principle
Pay-off System: Comprises a central pay-off stand and multiple planetary cradles; these support the cable reels and rotate with the stranding cage while utilizing a gear mechanism to achieve precise back-twist.
Main Stranding Cage: Constructed using thick-walled seamless steel pipe and supported by large-scale bearings, ensuring high rigidity and smooth operation; certain models support modular tandem configurations.
Control System: Modern units typically employ PLC and touchscreen controls combined with variable-frequency drive (VFD) motors to enable stepless lay-length adjustment and tension synchronization.
Key Application Areas
Power Transmission Cables: Production of high/medium-voltage power cables, Aluminum Conductor Steel Reinforced (ACSR) cables, and large-cross-section Milliken conductors.
Data and Communication Cables: Manufacturing of high-speed data cables—such as Ethernet, USB 3.1+, and QSFP—to ensure signal integrity and minimize crosstalk.
Specialty and New Energy Cables: Suitable for medical instrument cables, robotic drag-chain cables, automotive wiring harnesses, and high-current cables for EV charging stations.
Core Equipment Advantages
100% Back-twist Process: Effectively eliminates residual torque and prevents wire deformation, significantly enhancing the flexibility and service life of the finished product.
Adaptability to Complex Structures: Capable of handling high core counts, shaped conductors, and composite shielding structures, ensuring tight stranding layers and superior roundness.
Efficient Integrated Production: Allows for the in-line integration of processes such as taping and braiding, reducing the handling of semi-finished products and boosting overall production efficiency.
