Complete Sets Of Switchgear Production Line
10KV medium-voltage switchgear
35KV high-voltage cabinet
380V low-voltage cabinet
Production process
(Using Low-Voltage Cabinets As An Example)
• Sheet metal processing: sheet cutting → bending → welding (cabinet frame).
• Surface treatment: acid washing and phosphating → electrostatic spraying → curing.
• Assembly: installation of circuit breakers, meters, transformers, and other components.
• Wiring: complete primary bus (main circuit) and secondary control lines according to drawings.
• Testing: power frequency withstand voltage test (e.g., 42kV/1min), mechanical operation test (over 500 cycles without failure).
• Packaging: moisture-proof film + wooden crate, accompanied by factory inspection report.
Key technologies and equipment
• Intelligent technologies:
- MES system: Real-time monitoring of production progress and quality data, achieving traceable management.
- Flexible production lines: Adapting to different specifications of cabinets (such as mixed production of fixed and drawer types) through adjustable fixtures.
- Robot applications: Sheet metal bending robots, AGV material handling, etc.
• Typical equipment examples:
- Busbar processing center: Automatically completes copper bar cutting, punching, and bending.
- Wire harness automation: Such as fully automatic crimping machines combined with label printers.
Application Scenarios
• Power engineering: substation and new energy power station
• Industrial sector: distribution room for high-energy-consuming enterprises such as petrochemicals and metallurgy.
• Overseas projects: production of export cabinets that comply with IEC/ANSI standards.
