In medium- and high-voltage power cable manufacturing, the stranding and armoring stage determines mechanical strength, flexibility, and long-term reliability. The Tordeuse de tambours RLB avec blindage en fil d'acier provides a complete, space-saving 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.
This universal rotating machine draws on proven designs used by leading global manufacturers for HV Milliken conductors, power cables, screening, and armoring operations. By integrating steel wire pay-off and pre-twist units directly into the line, it eliminates the need for a separate armoring machine, significantly reducing floor space, labor, and production steps while ensuring consistent quality that meets IEC, GB, ASTM, and international standards.
Ideal for cable manufacturers supporting Saudi Vision 2030 power transmission projects, NEOM, Aramco-related infrastructure, and broader GCC energy and industrial developments, this machine produces high-quality steel wire armored (SWA) cables ready for underground and direct-buried installations.
Technological Process For Drum Twister
Pay-off Reels → Rotating Drum Twister Cage (with adjustable 0–100% back-twist) → Integrated Steel Wire Armoring Section (centralized pay-off + pre-twist) → Optional Filling & Taping Heads → Rotating Caterpillar or Large Drum Take-up → Finished Armored Multi-Core Cable
The single-pass design ensures stable synchronization, precise pitch control, and excellent armor adhesion from start to finish.
Fonctionnalités avancées et avantages du processus
- Flexible Back-Twist Control (0–100%): Freely adjustable via touchscreen for round or sector conductors, optimizing electrical performance and mechanical stress relief — critical for shaped conductors and long-term cable integrity.
- Blindage intégré en fil d'acier: Add centralized steel wire pay-off stands (bobbin or coil type) and pre-twist devices to produce fully armored cables in one operation. Supports up to 48/60/72/84/96 wires (typical 1.3–3.2 mm diameter) without extending line length.
- Precision Independent Drives: Each unit uses AC servo or induction motors with encoder feedback for high-precision synchronization. Rotating pay-off can operate independently, synchronized, or with individual speed control.
- Intelligent HMI + PLC Control: Store recipes, set lay length/direction/speed in real time, monitor production, and achieve automatic synchronization with take-up. Touchscreen interface simplifies operation and reduces training time.
- Remplissage et ruban adhésif optionnels: Integrate up to 24 filling bobbins and semi-tangential taping heads (non-metallic or copper tape) for complete multi-layer construction.
- Configuration robuste: Rotating caterpillar or large drum take-up handles finished cables up to Φ130 mm+ and heavy reels (up to 25–30 tons on larger models). Hydraulic lifting platforms ensure safe, efficient drum handling.
- Compact Line Design: Centralized steel wire pay-off positioned beside the main unit shortens overall production line length and reduces factory investment.
- Versatility: Suitable for LV/MV/HV power cables, Milliken segmental conductors (5–7 cores), screening operations, and even taping mode with stationary pay-off/take-up for very large cables.
These features deliver consistent lay length, tight armor adhesion, excellent bending performance, and reduced production costs — key advantages over traditional separate stranding and armoring lines.

FAQ détaillées – Répondre aux vraies questions de vos clients
Q1: What is the main advantage of the RLB Drum Twister over traditional stranding machines?
A: It combines laying-up and steel wire armoring in a single continuous pass with 0–100% adjustable back-twist, dramatically reducing production steps, floor space, labor, and overall manufacturing costs while improving cable consistency.
Q2 : La torsion arrière peut-elle être ajustée pour différents types de conducteurs ?
A: Yes. The rate is freely set from 0–100% on the touchscreen for optimal performance with round or sector (straight/pre-spiral) conductors, ensuring excellent electrical and mechanical properties.
Q3 : Est-ce compatible avec un blindage en fil d'acier ?
A: Yes. Integrated or add-on centralized steel wire pay-off and pre-twist devices enable full steel wire armoring in one operation — no separate armoring line required.
Q4 : Quel est le diamètre maximal du câble fini ?
A: Up to Φ130 mm or more depending on configuration, with heavy-duty rotating caterpillar or large drum take-up options for high-capacity production.
