Intelligent Production Line for Power Distribution Cabinets

Intelligent production lines integrate automation, robotics, and MES systems to efficiently manufacture complete sets of power distribution cabinets with high quality and flexibility.

Overview of Intelligent Production Lines

Modern production lines for power distribution cabinets are designed to combine sheet metal processing, assembly, wiring, testing, and packaging into a fully integrated workflow. These systems enable high-volume, standardized, and traceable production while maintaining flexibility for different cabinet specifications, such as fixed or drawer-type designs .

Key Production Stages

1. Sheet Metal Processing: Includes cutting, bending, and welding of cabinet frames. Advanced lines use CNC laser cutting and press brakes to ensure dimensional precision and consistent edge quality .
2. Surface Treatment: Cabinets undergo acid washing, phosphating, electrostatic spraying, and curing to enhance corrosion resistance and finish quality .
3. Assembly: Installation of circuit breakers, meters, transformers, and other components is performed with robotic assistance for accuracy and repeatability .
4. Wiring: Complete primary bus and secondary control lines are installed according to design drawings. Automated wire harness machines and label printers improve efficiency and reduce errors .
5. Testing: Cabinets undergo power frequency withstand voltage tests, mechanical operation tests, and functional inspections to ensure compliance with IEC, ANSI, UL, and NEMA standards .
6. Packaging: Finished cabinets are protected with moisture-proof film and wooden crates, accompanied by factory inspection reports for traceability .
