The GGD low voltage fixed switchgear can be widely applied to the power supply conversion, distribution and control of the power, lighting and distribution equipment of the power distribution system with the AC frequency of 50Hz and voltage of 400V of the power users of the power plant, power station and factory etc.
lThe ambient air temperature is not higher than +40℃ and no lower than -5℃. Its average temperature within 24 hours is not higher than +35℃.lThe weather condition should be as follows: The air is clean. The relative humidity should be not higher than 50% at the maximum temperature of +40℃. The higher relative temperature is allowed when the temperature is lower.
Notes: Please negotiate with us in case of out of the above-mentioned environmental conditions for normal use.
The GGD cabinet breaks through the structure form of the former product, with the basic framework of combined-assembled structure. All components of the framework are firmly connected by the screws. The polyester orange grain coating is carried out for the frame, door and panel after phosphating. All parts without being coated are galvanized and go through the passivating treatment. The protection grade of the outer hub is IP30 and it can be selected from IP20~IP40 according to the requirements of the installation site of the user. The design of this frame has good natural ventilation system.
The wiring mode of GGD includes the incoming forms from upper and lower parts. Meanwhile, the modes of incoming from the cabinet top, left, middle and right are also designed to meet the requirements of different incoming modes of various engineering designs. At the same time, the fixed location in the cabinet is reserved for the special users such as power plant etc. to install the relay protection and automatic devices.
The GGD cabinet has the characteristics of high disconnection capacity, good dynamic and thermal stability and flexible and easy electric plan combination etc.
