The construction of an explosion-proof positive-pressure cabinet refers to the external shape of the cabinet body, using a GGD cabinet body. According to the distribution of the positive-pressure explosion-proof chamber and the positive-pressure control chamber, the types are divided into upper-lower structure, left-right structure, and console structure. The door opening methods are also diverse, with front door opening for operation and rear door opening for maintenance.

Upper-lower structure: The positive-pressure chamber is located in the upper part of the cabinet body, and the positive-pressure control chamber is in the lower part; the door opening method is front and rear door opening, or front, rear, left, and right door opening; explosion-proof positive-pressure cabinets with a width below 1 meter or a height below 2.3 meters can adopt the left-right structure.。

Left-right structure: The positive-pressure chamber is located on the left side of the cabinet body, and the positive-pressure control chamber is on the right side; the door opening method is left-right double door opening, or front, rear, left, and right door opening; cabinets with a width above 1 meter or a height above 2.3 meters can adopt the left-right structure.。

Console structure: the positive-pressure chamber and control chamber are located in the lower part of the cabinet; the door opening method is front and rear doors; a console structure can be adopted for heights below 2 meters or thicknesses above 1 meter.
