A tubular stranding machine (also called tubular strander or pipe-type stranding machine) is a high-speed rotating-tube equipment that produces concentric stranded conductors with true 100% back-twist. It delivers uniform lay length, low residual torsional stress, high fill factor and continuous 24\/7 operation for copper, aluminum and steel wires used in low-, medium- and high-voltage power cables, ACSR\/AAC\/AAAC overhead conductors, control cables and steel wire ropes.<\/p>\n

Modern models achieve rotor speeds of 400\u20131,200 rpm and line speeds of 100\u2013230 m\/min while maintaining tension variance within \u00b12% and lay-length accuracy better than \u00b11%. This performance directly supports IEC 60228 Class 2 conductors and meets the dimensional and electrical requirements of IEC 60502 power cables.<\/p>\n

    How Does a Tubular Stranding Machine Work? Core Process and True 100% Back-Twist Principle<\/h3>\n

    The tubular stranding machine consists of a seamless steel rotating tube (cage), internal bobbin cradles, central pay-off, closing die, dual-wheel or single-wheel capstan, and take-up unit. Individual wire bobbins are loaded inside the tube. As the tube rotates at high speed, the wires are laid helically around a central core or around each other. Because the bobbins remain orientation-fixed relative to the ground (true back-twist), each wire experiences zero net torsion. The result is a stress-free conductor with superior flexibility, fatigue resistance and electrical uniformity.<\/p>\n

    Typical process sequence:<\/p>\n

      \n
    1. Pay-off (stationary or driven, single or batch loading with optional hoist).<\/li>\n
    2. Wire entry through low-friction guides into the seamless steel tube.<\/li>\n
    3. High-speed helical laying with constant tension control (band brake, magnetic particle or hysteresis brake).<\/li>\n
    4. Closing and optional compaction at the die.<\/li>\n
    5. Precise pitch control via independent servo-driven capstan.<\/li>\n
    6. Take-up onto PN1250\u2013PN2000 drums.<\/li>\n<\/ol>\n

      Line speeds of 120\u2013200 m\/min are routine for 7-wire and 12-wire constructions; higher-bay machines (18\u201336 bobbins) handle multi-layer ACSR cores and steel strands at lower but still productive speeds.<\/p>\n

      Core Technical Advantages & Operational Excellence<\/h3>\n

      True 100% Back-Twist Technology<\/strong><\/p>\n

      The tubular cage maintains bobbin orientation during high-speed rotation, completely eliminating internal torsional stress in the wires. This results in conductors with superior flexibility, excellent electrical performance, and enhanced long-term fatigue resistance \u2014 a significant advantage over non-back-twist or planetary stranders.<\/p>\n

      High-Speed Rigid Rotating Tube<\/strong><\/p>\n

      The seamless steel tube is supported by large heavy-duty precision bearings with an automatic pump lubrication and cooling system. This ensures stable, low-noise, and vibration-free operation even at rotor speeds up to 1200 rpm, supporting high-volume production with minimal maintenance.<\/p>\n

      Precise & Stable Tension Control<\/strong><\/p>\n

      Band-type brakes or optional German hysteresis brakes with electromagnetic compensation maintain constant wire tension from full to empty bobbin. This reduces wire breakage, minimizes scrap, and ensures consistent lay length and conductor quality throughout the production run.<\/p>\n

      Independent Servo Drive & Intelligent Control<\/strong><\/p>\n

      The main rotor, pulling capstan, and take-up unit are driven independently by servo motors. The advanced HMI + PLC control system allows easy pre-setting of stranding pitch, automatic tension compensation, and full-line synchronization with real-time monitoring.<\/p>\n

      Heavy-Duty Construction & Safety Features<\/strong><\/p>\n

      Designed for continuous 24\/7 operation, the machine handles copper and aluminum wires from 0.8 mm to 5.0 mm as well as steel wires. Safety features include wire-break detection and door-open stoppage for operator protection.<\/p>\n

      Compared with planetary or drum-type stranders<\/strong>, the tubular design generally offers higher output, lower scrap rates, better compaction, quieter operation, and reduced maintenance requirements.<\/p>\n

            Tubular stranding machines remain the most productive solution for high-volume, medium-size concentric conductors when true back-twist, low residual stress and continuous high-speed operation are required. Correct model selection based on wire diameter range, bobbin count, rotor speed and tension-control technology directly determines conductor quality, scrap rate and total cost of ownership. Modern units equipped with servo drives, centralized lubrication and digital pitch control meet current IEC\/GB requirements and support long-term production of reliable power and overhead cables.<\/p>","protected":false},"excerpt":{"rendered":"
