LD-o1250-1600Bow shaped Stranding Machine

Features:

Designed for the concentric stranding of copper wires (including PVC-insulated wires) or aluminum wires (up to 7, 19, or 37 strands). This system serves as an alternative to traditional tubular or cage-type stranding machines, offering an optimal balance of high processing speed and operational efficiency. It requires a lower initial investment while delivering high production capacity.

Equipment Application: This equipment is designed for stranding copper or aluminum wires, as well as for the dual-pitch cabling of multi-core conductors (for cables with a cross-sectional area of less than 50mm²).

Key Technical Parameters: (1) Input Wire Diameter: For stranded soft copper wire: 1.0–3.2 mm (up to 7 cores); for stranded PVC-insulated wire: 2.0–6.5 mm (2–7 cores); for stranded aluminum wire: 1.6–3.2 mm (up to 7 cores). (2) Stranding Cross-Sectional Area: 4–35 mm² for rigid conductors; 4–50 mm² for flexible conductors. (3) Lay Length Range: 35–400 mm (set via dial-type controls with automatic calculation and adjustment). (4) Stranded Outer Diameter: 3.0–20 mm for soft copper wire; 5.0–20 mm for PVC-insulated wire. (5) Lay Direction: S or Z (selectable). (6) Rotor Speed: 800 RPM (max.); 500 RPM (typical production speed). (7) Power System: Rotor – 42 kW servo motor with dedicated frequency converter; Capstan (haul-off) – 22 kW servo motor with dedicated frequency converter; Take-up – 7.5 kW servo motor with dedicated frequency converter; Traverse (wire laying) – 750 W gear motor.

(8) Take-up Spool Size: 1250 mm (max.); Load Capacity: 3500 kg (max.).

(9) Power Supply: 380V, 50Hz (or as specified by the customer).

(10) Spool Loading/Unloading: Electro-hydraulic lifting system with pallet-based loading/unloading.

(11) Low-Noise Design: Equipped with a soundproof safety enclosure; noise level kept below 85 dB.

(12) Braking: Pneumatic disc brake.

(13) Control System: PLC-based control, servo control, wire-break detection (with automatic stop), length-based automatic stop, safety limit switches, and internal machine lighting control. (14) Operating air pressure: 6 kg/cm².
