Machine de câblage rigide | Câbleuse haute efficacité sans torsion inverse pour blindage et blindage

In medium- and high-voltage power cable production, rigid stranding is the preferred technology for creating compact, mechanically strong armoring layers and shielding structures. The RLB Rigid Stranding Machine (ST56 and ST63 series) is a heavy-duty non-back twist strander engineered specifically for high-efficiency armoring with copper wires, round aluminum wires, pre-twisted sector conductors, and steel wires. It is also widely used for manufacturing copper wire shielded cables and copper tape shielding cables, delivering superior roundness, uniform lay length, and excellent long-term cable performance.

Brief Technological Process

Central Payoff → Rigid Cage Rotation → Precision Compaction → Take-Up Payoff reels (automatic side or front loading) → Rigid cage with multiple bobbins → Non-back-twist stranding at high rotational speeds (up to 550 rpm) → Precision die holder for round/sector compaction → Meter counter and dual-wheel capstan → Automatic take-up bobbin.

The concentric rigid design ensures smooth wire path, constant tension, and perfect synchronization between mechanical and electrical systems for stable, high-speed operation.

Core Technical Advantages & Operational Benefits

Engineered for the demanding GCC climate and high-volume armored cable production, the RLB Rigid Stranding Machine offers measurable performance advantages:

• True Non-Back Twist Rigid Stranding: Ideal for armoring and large-section conductors where stability, compactness, and mechanical strength are critical.
• Automatic Bobbin Loading: Side-lower or front automatic loading mechanisms (customizable) for faster changeovers, reduced labor, and minimal downtime.
• Constant Tension Control: Aerodynamic resistance combined with electromagnetic brakes provides precise, automatic tension compensation from full to empty bobbin.
• Robust Ground Shaft Drive System: Independent AC motors per cage ensure perfect electrical synchronization and stable high-speed operation with low noise and maintenance.
• Intelligent MMI + PLC Control: Easy pre-setting of stranding pitch, direction, tension compensation, and full synchronization with pulling capstan and take-up unit.
• Versatile Material Handling: Handles copper (1.5–3.6 mm), aluminum (1.75–5.0 mm), aluminum alloy, and steel wires with loading weights up to 1200 kg.

These features result in higher output, lower scrap rates, reduced energy consumption, and consistent high-quality armored and shielded cables compared to traditional planetary or tubular stranders.

Detailed FAQs – Answering Your Customers’ Real Questions

Q1: What is the main advantage of a Rigid Stranding Machine over planetary stranders?

A: The rigid cage design provides superior rigidity, higher rotational speeds, better compaction, lower energy consumption, and significantly reduced maintenance costs — ideal for large-section armored and shielded cables.

Q2: Does it support automatic bobbin loading?

A: Yes. Side-lower or front automatic loading mechanisms (customizable to your site) greatly reduce labor and changeover time.

Q3: Can it handle both copper and aluminum wires for armoring?

A: Yes. Fully versatile for copper (1.5–3.6 mm), aluminum (1.75–5.0 mm), aluminum alloy, and steel wires.

Q4: What is the maximum line speed and rotor speed?

A: Rotor speed up to 220 rpm (model dependent); line speed up to 320 m/min with excellent lay length uniformity.

Q5: Is online tension control and synchronization included?

A: Yes. Constant tension control and full MMI+PLC synchronization with pulling capstan and take-up ensure stable, high-quality production.

Q6: Do you provide installation and training in Saudi Arabia?

A: Yes. Full turnkey installation, commissioning, operator training (English), 24/7 remote diagnostics, and local spare parts support.
