Drum Twister With Steel Wire Armouring | Integrated High-Efficiency Laying-Up & Armoring Machine

In medium- and high-voltage power cable manufacturing, the stranding and armoring stage is critical for achieving mechanical strength, flexibility, and long-term reliability. The RLB Drum Twister with Steel Wire Armouring delivers a complete, high-efficiency solution for laying up 2-, 3-, 4-, or 5-core cables (round, straight-sector, or pre-spiral sector conductors) while simultaneously applying steel wire armor in a single continuous pass.

With adjustable back-twist from 0–100 %, independent AC servo drives, and full HMI+PLC control, this machine ensures precise lay length, uniform armor coverage, and excellent cable roundness — ideal for underground, direct-buried, and industrial power cables.

Brief Technological Process

Pay-off Reels → Rotating Drum Twister Cage → Steel Wire Armoring Section → Caterpillar / Take-up Multi-core conductors from pay-off stands → High-speed drum twister with adjustable back-twist (0–100%) → Integrated steel wire pay-off and pre-twist unit for simultaneous armoring → Optional filling and taping heads → Rotating caterpillar or large drum take-up → Finished high-quality armored multi-core cable.

The single-pass design significantly reduces floor space, labor, and production steps while ensuring consistent lay length and armor adhesion.

Advanced Features & Process Advantages

• Flexible Back-Twist Control: 0–100 % back-twist rate can be set freely on the touch screen for optimal electrical and mechanical performance.
• Integrated Steel Wire Armoring: Add steel wire pay-off and pre-twist devices to produce fully armored cables in one operation — no separate armoring line required.
• Intelligent Synchronization: HMI+PLC system allows pre-setting of laying-up pitch, direction, and speed; real-time monitoring and automatic synchronization with take-up ensure stable production.
• Optional Filling & Taping: Up to 24 filling bobbins and semi-tangential taping units (non-metallic or copper tape) can be integrated for complete multi-layer cable construction.
• Heavy-Duty Configuration: Available with rotating caterpillar or large drum take-up for cables up to Φ130 mm finished diameter.

The result is high-quality, armored multi-core cables with consistent lay length, excellent armor adhesion, and superior bending performance.

Detailed FAQs – Answering Your Customers’ Real Questions

Q1: What is the main advantage of a CPD Drum Twister over traditional stranding machines?

A: It combines laying-up and steel wire armoring in one pass with 0–100% adjustable back-twist, significantly reducing production steps, floor space, and costs.

Q2: Can back-twist be adjusted for different conductor types?

A: Yes. The rate can be set freely from 0–100% on the touch screen for round or sector conductors.

Q3: Does it support steel wire armoring?

A: Yes. Integrated steel wire pay-off and pre-twist devices allow full armoring in a single operation.

Q4: What is the maximum finished cable diameter?

A: Up to Φ130 mm, with heavy-duty caterpillar or large drum take-up for high-capacity production.

Q5: Is the machine suitable for complete turnkey lines?

A: Yes. As a leading cable and wire machinery supplier, we provide full integration with pay-off, stranding, extrusion, and testing systems.

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

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