GGD
The GGD cabinet breaks away from the structural form of older products, featuring a modular assembly framework where all structural components are securely fastened with screws. The frame, doors, and panels undergo phosphating followed by polyester orange peel textured coating, while all uncoated parts are galvanized and passivated. The enclosure protection rating is IP30, but can be customized between IP20 and IP40 based on the user’s installation environment requirements. The cabinet incorporates an effective natural ventilation system.
The GGD cabinet offers common top and bottom side cable entry configurations, along with additional entry points from the top, left, center, and right sides to accommodate diverse engineering design requirements. Reserved mounting locations inside the cabinet allow power plants and other specialized users to install relay protection and automatic control devices.
The GGD cabinet features high breaking capacity, excellent dynamic and thermal stability, and flexible electrical configuration options.
