1、 Overview and purpose
The GGD type AC low-voltage distribution cabinet is suitable for AC 50Hz, rated working voltage of 380V, and rated working current up to 3150A distribution systems for power plants, substations, factories, mines, and other power users. It is used for power conversion, distribution, and control of electrical energy for power, lighting, and distribution equipment.
The GGD type AC low-voltage distribution cabinet is a new type of low-voltage distribution cabinet designed based on the subjective requirements of the Ministry of Energy, the vast number of power users, and design departments, in accordance with the principles of safety, economy, rationality, and reliability. The product has the characteristics of high breaking point, good dynamic and thermal stability, flexible electrical scheme, convenient combination, strong series and practicality, novel structure, and high protection level. Can be used as a replacement product for low-voltage switchgear.
The GGD type AC low-voltage distribution cabinet complies with standards such as IEC439 "Low voltage switchgear" and GB7251 "Low voltage switchgear".
