GGD AC low-voltage distribution cabinet for power plants, substations, factory and mining enterprises and other users of the exchange of power 50Hz, rated working voltage 380V, rated current to 3150A of the distribution system, as power, lighting and power distribution equipment conversion, distribution and control purposes.
GGD AC low-voltage distribution cabinet is based on the majority of electricity customers and design requirements, based on security, economic, rational and reliable design of the new principle of low-voltage distribution cabinet. Product has high breaking capacity, good thermal stability of actin, electric program flexible combination of convenience, family, practical, and novel structure, high level of protection.
Distribution cabinets meet the IEC439 "Low-voltage switchgear and control equipment", GB7251.1-1997 "Low-voltage switchgear and control equipment" and other standards.

■ structural characteristics
□ GGD AC low-voltage distribution cabinet cabinets cabinet to adopt a common form of cold-formed steel frame with 8MF from local welding assembly, frame parts and a dedicated supporting beam fixed-point parts from suppliers supporting the production of plants in order to ensure the accuracy of cabinets and quality.
GM parts counter module according to the principle of design and installation of 20-hole mode. General coefficient of higher plants can be the realization of production, not only shorten the production cycle, but also increased efficiency.
□ GGD cabinet design of cabinets to take full account of the problem in the operation of the heat. Upper and lower ends of the cabinets have different number of cooling slots, when the electrical components inside of fever, the heat rising from the adoption of the top slot, while the cold wind constantly added into the slot from the bottom of cabinets, so that sealed cabinets form a natural bottom-up air duct to the purpose of cooling.
□ GGD cabinet according to the modern industrial product design requirements, using the method of Golden Section Design cabinets than the shape and size of various parts of the partition, so that the entire cabinet elegant, new look.
□ doors with hinge axis activities connected with the framework, installation, demolition convenience Department fold doors are embedded be a rubber-type, closed the door and frame have a certain嵌条between the compression stroke, to prevent the doors and cabinet direct collision of bodies, but also increased the protection level of doors.
□ instrument equipped with electrical components of the door with multi-strand soft copper wire connected with the framework. Inside the framework of the installation pieces and roll between the use of screws to connect to spend the whole of the ground to protect a complete circuit.
□ cabinets orange polyester topcoat selection shaped baking finish, strong adhesion, good texture, the whole cabinet was Yaguang hue, to avoid the blinding effect of the duty to create a more comfortable visual environment.
□ cabinets in the cap it can be removed and the main bus at the scene to facilitate the adjustment of the assembly, with the four corners of the rings柜顶for lifting and shipping.
□ cabinets protection IP 30, the user can also use the environment in accordance with the requirements in the choice between the IP20 ~ IP40.
