GGD arc resistant power control and switchgear has flexible electrical scheme, convenient combination, strong practicability, novel structure, high protection level, etc.
GGD fixed switchgear (hereinafter referred to as power distribution cabinet) is suitable for power users such as power plants, substations, industrial and mining enterprises as AC 50Hz (60Hz), rated working voltage 380V (400), (660), rated working current to The 3150A power distribution system is used for power conversion, distribution and control of power, lighting and power distribution equipment. The product has high breaking capacity, good dynamic thermal stability, and rated short-time withstand current up to 50KA. Flexible electrical scheme, convenient combination, strong practicability, novel structure, high protection level, etc. This product is one of the representative products of my country's assembled and fixed panel switchgear.
The power distribution cabinet has undergone a comprehensive type test and passed the national compulsory product 3C certification. This product complies with GB7251.1 "Low-Voltage Switchgear and Control Equipment", IEC60439-1 "Low-Voltage Switchgear and Control Equipment" and other standards.
1. The ambient air temperature does not exceed 40℃, and the average value measured within 24h does not exceed 35℃, and the minimum ambient air temperature is -5℃;
2. The altitude of the installation site does not exceed 2000m;
3. The surrounding air is not significantly polluted by dust, smoke, corrosive and soluble gases, steam or salt spray:
4. Atmospheric conditions: The air is clean, and the relative humidity should not exceed 50% when the maximum temperature is +40℃. At a lower temperature, a higher relative humidity is allowed. For example: The relative humidity is 90% at +20°C. However, it should be considered that due to temperature changes, moderate condensation may occasionally occur;
5. When the equipment is installed, the inclination from the vertical does not exceed 5°;
6. The equipment should be installed in a place where there is no severe vibration and impact.
