Q1：What are the primary applications of GGD Fixed Switchgear?
A: GGD switchgear is widely used in power plants, substations, and industrial enterprises for AC 50Hz, rated voltage 380V, and rated current up to 3150A power distribution systems. It is the ideal solution for power conversion, distribution, and control of lighting and power distribution equipment.
Q2：What are the structural advantages of the GGD cabinet?
A: The GGD cabinet adopts a universal frame design, welded with cold-formed steel (8MF). This structure provides high mechanical strength and precise dimensions. The modular hole pattern (E=20mm) allows for flexible installation of various components.
Q3：How does the GGD panel handle heat dissipation?
A: Heat management is a core feature of GGD. The cabinet is designed with ventilation slots at the top and bottom. When components heat up, the hot air rises and exits through the top vents, while cool air is drawn in from the bottom, creating a natural chimney effect for efficient cooling.
Q4：What is the maximum rated current and breaking capacity (Icw)?
A: Our GGD panels support a rated current up to 3150A. The rated short-time withstand current (Icw) can reach 50kA (1s), providing excellent stability and safety during short-circuit events in industrial power grids.
Q5：Can I customize the busbar material and configuration?
A: Yes. We use high-purity T2 copper busbars. To enhance conductivity and prevent oxidation, we offer tin-plating or silver-plating options. The busbars are arranged to meet your specific short-circuit withstand requirements and site installation needs.
Q6：What is the standard protection rating (IP) for GGD cabinets?
A: The standard rating is IP30, which is suitable for clean, dry indoor environments like electrical rooms. Depending on your project requirements, we can customize the enclosure to reach IP40 for better dust protection.
Q7：How do you ensure the electrical grounding safety of the panel?
A: Safety is paramount. Every GGD cabinet features a reliable grounding system. The doors are connected to the frame using flexible copper braided wires, and the entire frame is connected to the main grounding busbar to ensure a low-impedance path to the earth.
Q8：Is the GGD panel compatible with international circuit breaker brands?
A: Absolutely. While the GGD is a classic Chinese design, we can install international brands like Schneider, ABB, or Siemens, or high-performance local brands. The interior mounting plates are customized to fit the specific footprint of the breakers you choose.
Q9：What documentation is provided for international shipping?
A: For every export order from our Shanxi factory, we provide a complete technical file, including Single-Line Diagrams (SLD), general arrangement drawings, Factory Acceptance Test (FAT) reports, and English user manuals.
Q10：How do you handle the assembly and wiring quality?
A: We follow strict ISO9001 quality control. All wiring is performed by experienced technicians, using standard color-coding and clear identification tags. We ensure all terminal connections are torqued to specification and 100% of panels undergo a power-on simulation test before packing.
