In power cable and overhead conductor production, consistent lay length, optimal compaction and stress-free wire properties are essential for electrical performance and long-term mechanical reliability.
Le Tubular Stranding Machine delivers exactly that through true 100% back-twist technology. Individual wires maintain their orientation inside the rotating seamless steel tube, eliminating internal torsional stress. The result: conductors with superior flexibility, uniform pitch, tight compaction and excellent fatigue resistance — preferred by manufacturers supplying Saudi Vision 2030 infrastructure and GCC power projects.
Technological Process For Tubular Stranding Machine
- Pay-off — Single or batch loading from pay-off drums (optional hoist system).
- Wire entry into seamless steel tubular cage — Smooth, low-friction path.
- True 100% back-twist stranding — Rigid rotor rotates at high speed while bobbins remain orientation-fixed.
- Constant tension control — Band-type brakes or optional German hysteresis brakes with electromagnetic compensation.
- Independent servo-driven pulling capstan — Precise synchronization and lay length control.
- Finished stranded conductor — Ready for insulation, compaction, taping or armoring.
The tubular design ensures perfect mechanical/electrical synchronization, low noise and reliable continuous 24/7 production.
Core Technical Advantages & Operational Excellence
True 100% Back-Twist Technology
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 — a significant advantage over non-back-twist or planetary stranders.
High-Speed Rigid Rotating Tube
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.
Precise & Stable Tension Control
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.
Independent Servo Drive & Intelligent Control
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.
Heavy-Duty Construction & Safety Features
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.
Compared with planetary or drum-type stranders, the tubular design generally offers higher output, lower scrap rates, better compaction, quieter operation, and reduced maintenance requirements.

Reel Size vs Performance Reference
(typical for high-speed tubular configurations; exact values depend on final engineering)
Reel Size Φ200–Φ500 mm — Max rotation speeds decrease progressively with more bays (6B → 36B). Single wire diameter ranges:
- Aluminum: Φ0.8–4.0 mm
- Copper: Φ0.6–4.0 mm
- Steel: Φ0.2–3.0 mm
Higher bay counts (18B–36B) commonly used for steel wire rope or multi-layer ACSR core production. Full data tables available in downloadable PDF.
Optional configurations: 6/12/18/24/30/36 bay, magnetic particle or hysteresis brakes per bobbin, integral core pay-off for zero-twist core presentation, regenerative drive/UPS systems, soundproofing packages.
