Product Overview
GGD AC low-voltage power distribution cabinets are used in power users such as power plants, substatories, factories and mines, etc. In power distribution systems with an AC frequency of 50-60Hz, a rated operating voltage of 380 V and a rated operating current up to 3150A, they are used for power conversion, distribution and control of power, lighting and power 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 majority of power users and design departments of the Ministry of Energy, following the principles of safety, economy, rationality and reliability. The product features high breaking capacity, excellent dynamic and thermal stability, flexible electrical schemes, convenient combination, strong serialization and practicability, novel structure and high protection grade. It can be used as a replacement product for low-voltage complete switchgear.
GGD type AC low-voltage power distribution cabinets comply with national and industrial standards.
