|---|---|
By employing advanced concentric winding technology, this machine ensures 100% circumferential coverage of copper tape around cables, eliminating signal interference in high-voltage and industrial environments. Its high-speed operation (up to 150 m/min) combined with adaptive tension control (±1% accuracy) makes it ideal for mass production of power cables, control cables, and marine cables that demand strict compliance with IEC 60811 insulation standards and DNV GL marine certifications. The system supports 0.1-2.0 mm thick copper tapes (including tinned and annealed variants) with automated tape feeding and real-time defect detection, reducing manual intervention and improving production yield by 18% compared to traditional screening methods.
Screening Method: Multi-axis servo-controlled concentric winding with programmable lay angle (15°-45°) to optimize shielding effectiveness (≥90 dB at 1 GHz).
Material Compatibility: Handles tinned copper tape (ASTM B3), annealed copper tape (IEC 60228 Class 2), and high-strength copper alloys with tensile strength ≥300 MPa.
Production Speed: Variable speed range of 5-150 m/min via frequency conversion drive, with acceleration/deceleration rates adjustable from 0.5-2 m/s² to prevent tape stretching.
Tape Feeding System: Dual payoff stations with automatic tape splicing, equipped with magnetic powder brakes for constant tension control (5-50 N) and laser alignment guides for precise positioning.
Winding Head: 4-12 spindle configuration with hardened steel guide rollers (Ra ≤0.4 μm), featuring quick-change spindle adapters for 30-second tape width adjustments (10-50 mm).
Defect Detection: Integrated ultrasonic thickness sensors (±0.01 mm accuracy) and machine vision cameras that identify tape breaks, overlaps <15%, and surface imperfections, triggering alerts within 0.3 seconds.
PLC+HMI Interface: 10.1-inch touchscreen with recipe storage (50+ profiles) for quick recall of parameters like pitch (5-50 mm), overlap percentage, and tension settings.
Safety Features: Emergency stop buttons at 3 stations, safety light curtains around winding area, and over-temperature protection (≥60°C) for drive motors.
Power Transmission Cables
Manufactures 110-220kV XLPE cables with copper screening for substation connections, reducing electromagnetic interference from nearby transformers by 40%.
Industrial Control Cables
Produces multi-core control cables for factory automation (e.g., Siemens S7 PLC systems), ensuring signal attenuation ≤5% over 100-meter runs.
Marine & Offshore Cables
Processes water-blocking submarine cables with tinned copper screening, meeting IEC 60727 requirements for salt fog resistance (500-hour ASTM B117 testing).
Aerospace Wiring
Creates lightweight aircraft cables with flame-retardant screening, complying with FAR 25.853 fire safety standards and reducing weight by 15% vs. braided shielding.
Q: What tape widths can the machine accommodate?
A: It supports standard tape widths from 10-50 mm, with custom adapters available for 5-10 mm narrow tapes used in micro-cables.
Q: How often is maintenance required for the winding head?
A: Spindles require lubrication with polyurea grease (NLGI 2) every 200 operating hours, and guide rollers should be inspected for wear every 500 hours (replace when surface roughness exceeds Ra 0.8 μm).
Q: Can it integrate with MES systems for production tracking?
A: Yes, it features OPC UA communication protocol for real-time data transfer to manufacturing execution systems, including production counts, defect rates, and uptime metrics.
