In medium- and high-voltage power cable manufacturing, rigid stranding technology is widely recognized as the most effective method for producing compact, mechanically strong armoring layers and shielding structures. Unlike planetary or tubular stranders, rigid cage stranders offer superior rigidity, higher rotational speeds, better compaction, and significantly lower maintenance requirements.
O RLB Rigid Stranding Machine (ST56 and ST63 series) is a heavy-duty non-back-twist strander specifically engineered for high-volume armoring and shielding applications. It is ideal for steel wire armoring, copper wire shielding, copper tape shielding, round aluminum wire armoring, and pre-twisted sector conductor stranding.
With its robust ground shaft drive system, automatic bobbin loading, and intelligent constant tension control, this machine delivers consistent high-quality output with excellent productivity — making it a preferred choice for cable manufacturers in Saudi Arabia and the GCC.
Technological Process
Payoff reels (automatic side or front loading) → Rigid cage with multiple bobbins → Non-back-twist stranding at high rotational speeds → Precision die holder for round or sector compaction → Meter counter and dual-wheel capstan → Automatic take-up bobbin.
The concentric rigid cage design ensures a smooth wire path, constant tension, and perfect synchronization between mechanical and electrical systems, enabling stable high-speed operation with minimal vibration.
Temel Teknik Avantajlar ve Operasyonel Faydalar
True Non-Back Twist Rigid Stranding The rigid cage design provides exceptional stability and compaction, making it ideal for armoring layers and large-section conductors where mechanical strength and roundness are critical.
Automatic Bobbin Loading System Available with side-lower or front automatic loading mechanisms. This significantly reduces changeover time, lowers labor requirements, and minimizes production downtime.
Constant Tension Control Aerodynamic resistance combined with electromagnetic brakes provides precise, automatic tension compensation from full to empty bobbin, ensuring uniform lay length and high-quality stranding throughout the entire bobbin.
Robust Ground Shaft Drive System Independent AC motors per cage deliver perfect electrical synchronization, stable high-speed operation, low noise, and reduced maintenance compared to traditional drive systems.
Intelligent MMI + PLC Control Easy pre-setting of stranding pitch, direction, tension compensation, and full synchronization with the pulling capstan and take-up unit. The system supports recipe storage for different products.
Çok Yönlü Malzeme Taşıma Handles copper wires (1.5–3.6 mm), aluminum and aluminum alloy wires (1.75–5.0 mm), and steel wires, with bobbin loading capacity up to 1200 kg.
These features deliver higher output, lower scrap rates, reduced energy consumption, and consistent high-quality armored and shielded cables.
