GGD Low-Voltage Complete Switchgear Series
The GGD-type AC low-voltage switchgear is designed for power distribution systems in power plants, substations, industrial facilities, and other electricity-consuming facilities. It operates on 50Hz AC, with a rated working voltage of 380V and a rated operating current up to 3150A. This equipment is used for the conversion, distribution, and control of electrical energy in power, lighting, and general-purpose distribution systems.
The GGD-type AC low-voltage distribution cabinet is a new-generation low-voltage switchgear designed in accordance with the requirements of the Ministry of Energy’s supervisory authorities, as well as feedback from extensive power users and design departments—always prioritizing safety, economy, rationality, and reliability. This product boasts high breaking capacity, excellent dynamic and thermal stability, flexible electrical configurations, convenient modular assembly, strong series compatibility, outstanding practicality, innovative structural design, and superior protection ratings. As such, it can serve as a modern replacement for traditional low-voltage complete switchgear systems.
The GGD-type AC low-voltage distribution cabinet complies with standards such as IEC 439 "Low-Voltage Switchgear and Controlgear Assemblies" and GB 7251 "Low-Voltage Complete Switchgear."
Terms of Use
· The ambient air temperature shall not exceed +40°C or fall below -5°C, and the average temperature over 24 hours must remain below +35°C.
· For indoor installation only; the altitude of the installation location must not exceed 2000 meters.
· The relative humidity of the surrounding air should not exceed 50% at a maximum temperature of +40°C, though higher relative humidity levels are permissible at lower temperatures (e.g., up to 90% at +20°C), taking into account the potential for occasional condensation caused by temperature fluctuations.
· The equipment must be installed with an inclination of no more than 5° from the vertical plane;
· The equipment should be installed in a location free from severe vibrations and shocks, as well as in an environment where electrical components won’t be exposed to corrosion.
· Users with special requirements may coordinate with the manufacturer for a solution.
