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.

产品介绍

      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. 
      The GGD low voltage distribution cabinet has characteristics of high disconnection capacity, good dynamic and thermal stability, novelty and reasonable structure, practical electric plan, strong series and applicability and high protection grade etc. Therefore, it can be used as an upgrading product.
      This product complies with the standards such as IEC60439 Low Voltage Switchgears and Control Equipment, GB7251.1 Part I: General Rules of Low Voltage Switchgears and Control Equipment, Part II: Complete Electric Switches and Control Equipment of Low Voltage Switchgears and Control Equipment etc.

Normal Use Conditions 

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.
lThe altitude is not higher than 2,000m.
lThis product is applicable to the transportation and storage under the following temperatures: within -25℃~+55℃ and the temperature can reach +70℃ in a short time (no longer than 24 hours). Under such limit temperature, the device should not suffer any unrecoverable damage and should operate normally under the normal conditions.

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.
