First, GGD low-voltage distribution cabinet product overview
GGD AC low-voltage distribution cabinet can be widely used in power plants, substations, factories and mining enterprises and other power users, in the AC 50Hz, rated working voltage 380V, rated current to 3150A distribution system, as power, lighting and distribution equipment for power conversion, distribution and control.
GGD type AC low-voltage power distribution cabinet is a new type of low-voltage power distribution cabinet designed by the company according to the requirements of the Department of Energy supervisor, the majority of power users and the design department, in line with the principles of safety, economy, reasonable and reliable. Cable entry modes include upper, lower side, left, middle, right and rear of cabinet top, to meet the actual needs of various projects for different cables. At the same time, there is a fixed position in the cabinet for the power plant and special users to install mechanical and electrical protection and automatic devices. The product has the characteristics of high breaking capacity, good dynamic and thermal stability, flexible electrical scheme, convenient assembly, series and practicability, novel structure, high protection level, and can be used as the replacement of low-voltage switchgear.
Two, GGD low voltage distribution cabinet operating conditions
a. Ambient air temperature is not higher than +40℃, not lower than -5℃. The average temperature within 24h shall not be higher than +35℃;
b. For indoor installation and use, the altitude of the use place shall not exceed 2000M;
c. The relative humidity of the surrounding air does not exceed 50% when the maximum temperature is +40 ° C, and a larger relative humidity is allowed at a lower temperature (such as 90% at +20 ° C), which should take into account the effect of condensation that may occur occasionally due to changes in temperature;
d. The inclination between the vertical plane and the installation of the equipment shall not exceed 5%;
e. The equipment should be installed in a place without severe vibration, and in a place where insufficient electrical components are corroded; Users have special requirements can be negotiated with the manufacturer to solve.
