Overview
GGD Low Voltage Fixed Switchgear is suitable for power users such as power plants, substations, and industrial and mining enterprises, operating in AC 50Hz power distribution systems with a rated voltage of 380V and a rated current up to 3150A. It is used for power conversion, distribution, and control of power, lighting, and distribution equipment.
Designed based on the requirements of the Ministry of Energy and electric power users and design departments, the GGD low voltage fixed switchgear follows the principles of safety, economy, rationality, and reliability. It is a new type of low-voltage distribution cabinet with features such as high breaking capacity, strong dynamic and thermal stability, flexible electrical schemes, convenient combination, strong applicability, innovative structure, and high protection level. It is an ideal replacement product for traditional low-voltage switchgear.
The GGD switchgear complies with IEC 439 “Low-voltage switchgear and controlgear assemblies” and GB 7251 “Low-voltage switchgear assemblies”.
Operating Conditions
1. Ambient temperature: -5℃ ~+40℃ , daily average temperature +35℃;
2. Altitude: ≤2000m, indoor type;
3. Ambient relative humidity at highest temperature +40 not exceed 50%;Allowed max relative humidity at low temperature, example for +20 is 90%, it will occur moderate moist due to temperature change;
4. Vertical installation, gradient: 5%;
5. Occasions without flammable and explosive matter, without corrosive chemical and frequent severe vibration.
