In the production of power cables and overhead conductors, achieving consistent lay length, excellent compaction, and stress-free wire properties is essential for both electrical performance and long-term mechanical reliability.
O RLB Boru Bükme Makinesi (also known as tubular type stranding machine or tubular strander) is a heavy-duty, high-speed solution engineered for precision stranding of 7-wire, 12-wire, and 19-wire round or sector-shaped copper and aluminum conductors, as well as galvanized steel wires.
Featuring true 100% back-twist technology within a rigid rotating seamless steel tube supported by large precision bearings and automatic lubrication systems, this machine delivers silent, vibration-free operation at speeds up to 1200 rpm. It produces conductors with superior flexibility, uniform lay length, tight compaction, and excellent electrical properties — making it a preferred choice for cable manufacturers in Saudi Arabia and the GCC.
Technological Process For Tubular Stranding Machine
Individual wires from pay-off drums (single or batch loading) → Enter the seamless steel tubular cage → 100% back-twist stranding at high rotor speed → Constant tension control via band-type or hysteresis brakes → Independent servo-driven pulling capstan → Finished high-quality stranded conductor ready for insulation, compaction, or armoring.
The tubular design provides a smooth wire path, perfect mechanical and electrical synchronization, and low-noise operation, enabling reliable continuous 24/7 production.
Temel Teknik Avantajlar ve Operasyonel Mükemmellik
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.
