| High Light | Overload Protected Control Panel Assembly ，Power Station Control Panel Assembly | ||
Designed for heavy-industrial applications, this large-scale distribution panel assembly provides stable power distribution, structured circuit protection, and continuous operational safety in high-demand environments such as manufacturing plants and central power stations.
The assembly integrates heavy-duty enclosure structural framing with high-capacity busbar routing and calibrated circuit protection components to prevent single-point overload failures.
| Parameter | Specification / Standard |
|---|---|
| Rated Operational Voltage (Ue) | Up to 690 V AC / 1000 V DC |
| Rated Insulation Voltage (Ui) | 1000 V AC |
| Main Busbar Current Rating | 1600 A - 6300 A (High-conductivity T2 ETP Copper) |
| Short-Time Withstand Current (Icw) | Up to 100 kA / 1 s |
| Peak Withstand Current (Ipk) | Up to 220 kA |
| Protection Degree (IP Rating) | IP54 / IP65 (NEMA 3R / NEMA 4 options available) |
| Enclosure Material | 2.0 mm - 2.5 mm Cold-Rolled Galvanized Steel / Stainless Steel 304 |
| Form of Internal Separation | Form 3b / Form 4b (IEC 61439-2) |
| Overload & Short-Circuit Protection | Integrated Air Circuit Breakers (ACB) & Molded Case Circuit Breakers (MCCB) with adjustable electronic trip units |
| Operating Temperature Range | -25°C to +55°C |
Constructed using 2.5 mm heavy-gauge galvanized steel framing, the enclosure is engineered to withstand substantial mechanical stress, thermal expansion, and seismic vibrations. The internal structural chassis prevents cabinet deformation during heavy-duty busbar installation and full-load operations.
Equipped with electronic trip units (LSIG: Long-time, Short-time, Instantaneous, Ground fault), the panel detects micro-fluctuations and thermal build-up before system failure occurs. Integrated trip monitoring prevents cascade tripping across secondary factory feeders.
Internal layout isolation between main busbar compartments and breaker units ensures efficient heat dissipation. Natural thermal convection paths combined with optional forced-air cooling systems keep internal temperature rises well within IEC limits.
Our production processes follow strict standardization protocols to ensure dimensional accuracy, structural durability, and electrical consistency across all custom assemblies.
| Manufacturing Stage | Execution & Verification Standard |
|---|---|
| Sheet Metal Fabrication | Precision CNC laser cutting and automated bending within ±0.1 mm tolerances |
| Busbar Processing | CNC bending, punching, and nickel/tin plating for minimized contact resistance and corrosion prevention |
| Assembly & Wiring | Color-coded wire harness management according to IEC/UL schematics; secondary circuit insulation isolation |
| Factory Acceptance Testing (FAT) | 100% dielectric insulation resistance testing, primary current injection, and trip simulation verification prior to dispatch |
