In medium- and low-voltage power cable manufacturing, the laying-up stage is critical to final cable roundness, lay length consistency, and long-term electrical performance. The RLB 3-5 Core Power Cable Laying Up Machine (cage/cradle planetary type) is a high-precision, heavy-duty solution engineered specifically for stranding 3-, 4-, and 5-core power cables using round, straight-sector, or pre-spiral sector conductors.
Built with true 100% back-twist technology, independent AC servo or frequency-controlled drives, and advanced HMI+PLC control, this machine ensures superior cable geometry, minimal internal conductor stress, and high production efficiency. Optional filling (up to 24 bobbins) and online taping further enhance its versatility for complete cable production lines.
Processus technologique
- Pay-off Cradles — Insulated cores (round or sector) are loaded into rotating planetary cradles with independent back-twist capability.
- Planetary Cage Rotation (100% Back-Twist) — The cage rotates while each cradle maintains bobbin orientation, applying precise back-twist to eliminate torsional stress.
- Haul-Off — Dual-wheel capstan (for smaller cables) or heavy-duty caterpillar (for larger power cables) provides stable, synchronized traction.
- Remplissage et ruban adhésif optionnels — Yarn fillers from up to 24 bobbins and semi-tangential taping heads can operate simultaneously.
- Prendre — Large drum take-up with traverse ensures neatly wound, high-quality finished cable.
This process produces multi-core power cables with excellent roundness, uniform lay length, and low internal stress — directly translating to superior electrical reliability and easier installation.
Fonctionnalités avancées et avantages du processus
- True 100% Back-Twist Stranding — Delivers excellent roundness, stable lay length, and minimal conductor stress. Essential for power cables requiring superior bending performance and long service life.
- Independent Servo / AC Drives — Main rotor, haul-off (capstan or caterpillar), and take-up operate independently for precise synchronization and automatic pitch adjustment.
- Intelligent HMI+PLC Control — Easy pre-setting of laying-up pitch, speed synchronization, real-time monitoring, and production data logging.
- Flexible Haul-Off Options — Interchangeable dual-wheel capstan or heavy-duty caterpillar to match cable size and production requirements.
- Optional Filling & Taping Integration — Supports up to 24 filling bobbins and compatibility with semi-tangential taping machines for simultaneous laying-up and taping.
- Manipulation robuste des bobines — Side, front, or back crane loading for fast changeovers and reduced downtime.
- Heavy-Duty Construction — Premium components and proven design for stable 24/7 operation with minimal maintenance in harsh industrial environments.
Conductor Range: Copper ≥ Φ1.5 mm | Aluminum ≥ Φ1.7 mm. Handles round cores (16–300 mm²), sector cores (16–240 mm²), and pre-spiral cores (up to 400 mm² depending on model).
