In the production of overhead transmission conductors and specialty cables, achieving consistent lay length, excellent roundness, and stress-free wire properties is critical to long-term performance and reliability. Traditional tubular or planetary stranders often introduce torsional stress into individual wires during the stranding process, which can negatively affect conductor flexibility, fatigue resistance, and electrical characteristics.<\/p>\n

\u0627\u0644 RLB Cage Type Stranding Machine<\/strong><\/a> (Models 500 and 630) addresses these challenges through its advanced 100% back-twist<\/strong> design. By maintaining bobbin orientation throughout the rotation cycle, this machine completely eliminates internal torsional stress in the wires. The result is a high-quality stranded conductor with superior mechanical and electrical properties.<\/p>\n

This stranding solution is particularly well-suited for manufacturers in Saudi Arabia and the GCC producing ACSR (Aluminum Conductor Steel Reinforced)<\/strong><\/a>, AAAC<\/strong><\/a>, bare copper and aluminum conductors, OPGW (Optical Ground Wire)<\/strong><\/a>, and multi-core control and instrumentation cables. With flexible configurations from 6B to 24B and robust engineering, it supports both high-volume standard production and specialized cable requirements.<\/p>\n

Core Technology & Engineering Advantages<\/h2>\n

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

The defining feature of this cage-type strander is its ability to perform genuine 100% back-twist stranding. Unlike conventional stranders that apply twist to individual wires, the cage design keeps each bobbin level during rotation. This eliminates torsional stress within the wires, resulting in conductors with improved flexibility, better fatigue resistance, superior roundness, and enhanced long-term electrical performance \u2014 particularly important for overhead lines subjected to wind, ice, and thermal cycling.<\/p>\n

Precision Constant Tension Control System<\/strong><\/p>\n

The machine is equipped with magnetic hysteresis tension controllers combined with automatic bobbin diameter detection. Real-time data is fed to the PLC, enabling automatic tension compensation from full to empty bobbin. This ensures highly stable tension throughout the entire production run, significantly reducing wire breakage, minimizing scrap, and improving overall conductor quality.<\/p>\n

Advanced Drive System and Full-Line Synchronization<\/strong><\/p>\n

Available with either a DC main motor with ground shaft transmission or individual AC servo motors for each cage section. The intelligent MMI + PLC control system allows precise pre-setting of stranding pitch, stranding direction, and automatic tension compensation. Full synchronization with the dual-wheel capstan and take-up unit ensures smooth, stable operation even at high speeds.<\/p>\n

Flexible Configuration and Heavy-Duty Design<\/strong><\/p>\n

The machine supports configurations from 6B to 24B, with options for additional filling devices. It accommodates large payoff reels (PN500\/PND500) and take-up reels up to PN2500, with a maximum stranded conductor outer diameter of up to \u03a650 mm. Bobbin handling can be performed using loading cranes or automatic loading cars, improving safety and reducing changeover time.<\/p>\n

High Productivity with Low Maintenance<\/strong><\/p>\n

Stepless lay length adjustment, robust mechanical construction, and seamless integration with downstream equipment (such as filling, taping, or armoring lines) enable efficient multi-layer cable production. The design prioritizes reliability and ease of maintenance for continuous 24\/7 operation.<\/p>\n
