High/Low Voltage Complete Plant

GGD AC Low Voltage Power Distribution Cabinet

GGD AC low-voltage distribution cabinet is a new type of low-voltage distribution cabinet designed on the principle of safety, economy, rationality and reliability according to the requirements of the supervisor of the Ministry of Energy, the majority of power users and design departments. The product has the characteristics of high sectional ability, good dynamic and thermal stability, flexible electrical scheme, convenient combination, strong practicability, novel structure and high protection level. It can be used as an updated product of low-voltage switchgear.

GGD AC low-voltage distribution cabinet is suitable for power users such as power plants, substations, factories and mines, etc., with AC 50Hz, rated operation voltage of 380V and rated working current of 3150A, and is used for power conversion, distribution and control of power, lighting and distribution equipment.

GGD AC low-voltage distribution cabinet conforms to IE0439 “Low-voltage switchgear and control gear”, GB7251 “Low-voltage switchgear and other standards”.

Operation environment

1. The ambient air temperature is not higher than+40°C and not lower than-5°C. The average temperature within 24 hours shall not be higher than+35°C.

2. Indoor installation and use, the altitude of the place of use shall not exceed 2000 meters.

3. The relative humidity of ambient air shall not exceed 50% at the highest temperature of+40°C, and a larger relative temperature is allowed at the lower temperature. (for example, 90% at +20°C) The influence of condensation that may occasionally occur due to temperature change should be considered.

4. When the equipment is installed, the inclination from the vertical plane shall not exceed 5%.

5. The equipment should be installed in a place where there is no violent vibration and where the electrical components are not corroded.

6. Users can negotiate with the manufacturer to solve special requirements.
