GGD low voltage fixed power distribution cabinet
Overview
      GGD type low-voltage fixed switchgear can be widely used in power distribution systems of power users, substations, factories and mines, etc. with 50Hz rated low voltage 400V rated current to 6300A, as power, lighting and distribution. Power conversion, distribution and control of electrical equipment.
      GGD low-voltage power distribution cabinet has the characteristics of high breaking capacity, good dynamic thermal stability, novel and reasonable structure, practical and practical electrical scheme, series, high applicability and high protection level. It can be used as a newer product.
      This product complies with IEC60439 "Low-voltage switchgear and control equipment", GB7251.1 "Low-voltage switchgear and control equipment Part 1: Type test and partial type test equipment" and other standards.
Normal use conditionFeatures
      ● The ambient air temperature is not higher than +40 ° C, not lower than -5 ° C, and its average temperature is not higher than +35 ° C within 24 hours.
      ● Relative humidity does not exceed 50% at a maximum temperature of +40 ° C, allowing higher relative humidity at lower temperatures.
      ● The altitude does not exceed 2000 meters.
      ●Applicable temperature between -25 ° C and 55 ° C, in a short time (not more than 24 hours) up to +70 ° C
      ● If the above conditions of use cannot be met, the seat will be submitted to the manufacturer at the time of ordering by the user and negotiated.
Features
      The GD cabinet breaks through the structural form of the old product. The basic frame is a combined assembly structure. All the structural parts of the frame are firmly connected by screws. The long door and the door and the panel are phosphatized and then used for polyester polishing. The parts are all galvanized and passivated. The enclosure protection grade is IP30, and it can also be selected between IP2~IP40 according to the requirements of the user installation site. The cabinet is designed with a good natural ventilation system.
      The GGD incoming line has the usual upper and lower side incoming lines. At the same time, the top, left, middle and right line entry modes are also designed to meet the requirements of different engineering design for different incoming lines. At the same time, there is a fixed position in the cabinet to install relay protection and automatic loading for special users such as power plants.
      The GGD cabinet has the characteristics of high breaking capacity, good dynamic thermal stability, and flexible and convenient combination of electrical solutions.
