GGD AC LOW-VOLTAGE DISTRIBUTION CABINET

GGD AC LOW-VOLTAGE DISTRIBUTION CABINET

GGD AC low voltage distribution cabinet is used for power users such as power plants, substations, factories, and mining enterprises. It serves as an AC 50-60Hz distribution system with a rated working voltage of 380V and a rated working current up to 3150A. It is used for power conversion, distribution, and control of 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 requirements of the Ministry of Energy’s power users and design departments, following the principles of safety, economy, rationality, and reliability. The product has the characteristics of high breaking capacity, 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 national and industry standards.
