GGD low-voltage distribution cabinet

GGD AC low-voltage power distribution equipment for power plants, substations, industrial enterprises and other power users of AC 50Hz, rated working voltage 380V, rated current up to 3150A of the distribution system, as power, lighting and power distribution equipment, power conversion , distribution and control purposes.

GGD AC low with piezoelectric cabinet is based on the requirements of the Department of Energy in charge of the higher level, the majority of electricity users and design department, in a safe, economic, rational and reliable design principles of new low-voltage distribution cabinet. Products with high breaking capacity, dynamic thermal stability, electrical program flexible combination of convenience, family, practical, novel structure, high level of protection. Low-voltage switchgear as the replacement product.

GGD AC low-voltage distribution cabinet meet IEC439 "Low-voltage switchgear and control equipment", GB7251 "Low-voltage switch equipment" and other standards.

Conditions of Use

1, ambient air temperature does not exceed + 40oC, not less than -5oC, the average temperature within 24h shall not exceed + 35oC.

2, the indoor installation altitude place of use shall not exceed 2000M.

3, ambient air relative humidity at the highest temperature is + 40oC does not exceed 50%, at a lower temperature allows a greater relative humidity. (For example, 90% at + 20oC) should take into account changes in temperature may occasionally produce condensation effects.

4, equipment installation and the vertical gradient of not more than 50%.

5, the device should be installed in my place severe vibration and shock, as well as inadequate electrical components are corrosion sites.

6, users have special requirements can be resolved through consultation with the manufacturer.

Structural features

1, GGD AC low-voltage distribution cabinet cabinet in the form of universal cabinet, cold-formed steel frame with 8MF local welding assembled, the frame parts and special fittings from the steel plant sentinel matching supply to ensure that the cabinet precision and quality. General principles of cabinet components by module design and module mounting holes 20, the common factor. It can realize the plant production. Only shorten the production cycle, but also improve work efficiency.

2, GGD cabinet designed to take full account of the cabinet to run the heat. The upper and lower ends of the cabinet have a different number of cooling slots when the electrical components inside the heat, the heat does not rise through the top slot discharge, and the cold wind constantly added into the cabinet from the bottom of the slot, the sealing of the cabinet form a natural ventilation path from bottom to top, for cooling purposes.

3, GGD cabinet according to the modern industrial product design requirements, using methods designed golden ratio cabinet shape and size of each part of the split, so that the entire cabinet nice, new look.
