Introduction
The GGD type AC low voltage power distribution cabinet is suitable for power users such as power plants, substations, and industrial and mining enterprises. It is designed for power distribution systems with a frequency of AC 50Hz, a rated working voltage of 380V, and a rated working current up to 3150A. It is used for power conversion, distribution, and control of electrical energy for power, lighting, and distribution equipment.
The GGD type AC low voltage power distribution cabinet is a new type of low voltage power distribution cabinet designed in accordance with the requirements of the supervisory authorities under the Ministry of Energy, as well as the needs of a broad range of power users and design departments. It is developed based on the principles of safety, economy, rationality, and reliability.
The product features high breaking capacity, good dynamic and thermal stability, flexible electrical design, convenient combination, series compatibility, strong practicality, innovative structure, and specific protection levels. It can be used as an updated and replacement product for low-voltage complete switchgears.
The GGD type AC low voltage power distribution cabinet meets standards such as IEC 439 Low Voltage Complete Switchgears and Control Equipment and GB 7251 Low Voltage Complete Switchgears.

Use conditions
