Power distribution cabinets typically consist of a base, side panels, partition doors, and a top cover. Internally, they are divided into high-voltage, transformer, and low-voltage compartments. Their structural design often considers equipment heat dissipation, protection, and ease of maintenance to meet the demands of long-term, high-intensity operation. The materials used for power distribution cabinet enclosures are diverse, including ordinary cold-rolled steel, aluminum, hot-dip galvanized steel, aluminum alloy, sandwich color steel, and non-metallic materials. Non-metallic materials are widely used due to their high mechanical strength, heat resistance, moisture resistance, flame retardancy, and corrosion resistance.
