1. Machine Overview
The 2000 CNC New-Type Cantilever Single Twist Machine is engineered for large‑cross-section multi‑core cables, especially in applications requiring high-capacity output and stable lay control. Without a traction wheel, this machine relies on differential-driven take-up for consistent twist pitch and high mechanical reliability. Ideal for high-volume cable production such as EV charging, power distribution, and heavy-duty control wiring.
2. Main Features
Large Bobbin Capacity: Supports take-up drums up to φ2000 mm, enabling long continuous runs and reduced reel change frequency.
Flexible Pitch Control: PLC-driven stepless pitch adjustment allows a wide range of lay lengths, adapting to different cable designs.
S/Z Twist Direction: Switchable “S” and “Z” lay provides flexibility for various cable construction demands.
High Stability Drive: Differential transmission from main drive to take-up ensures stable twist, even at high speeds, without traction wheel slip.
Active De‑twist Pay-Off: Multiple pay-off units with active de‑twist capability ensure stress-free feeding of large conductors.
High‑Power Motors: Powerful drive units matched to large cable cross-sections.
Advanced Control System: PLC + HMI for real-time monitoring, alarms, and automated operations.
Safety & Protection: Full protection including reel-position detection, break detection, and soft stop to maintain machine and product integrity.
3. Application
High cross-sectional power cables (e.g., large multi-core charging or power distribution cables)
Electric vehicle charging connector cables and harnesses
Multi-core control wiring with large conductor sizes
High-performance custom cable lines where long lay length and high precision are required
Cable factories aiming to reduce downtime by using large-diameter take-up reels
