| Basic Info. | ||
| Product Overview | ||
| GGD type AC low voltage distribution cabinet is applicable to power distribution of low voltage distribution systems such as power plants, substations, petrochemical departments, industrial and mining enterprises, high-rise buildings, and power distribution systems with AC frequency of 50Hz, rated working voltage of 380V, rated working current of 3150A for power users such as motor control centers, capacitor compensation, etc., as well as power conversion, distribution and control of power, lighting and distribution equipment. GGD AC low-voltage distribution cabinet is a low-voltage distribution panel designed by the Ministry of Energy for the purpose of promoting technical progress in China's low-voltage distribution industry and accelerating the upgrading of low-voltage distribution switchgear. The product has the characteristics of high breaking capacity, good dynamic and thermal stability, and strong practicability. |

| Functional Unit | ||
| The module of drawer floor height is 160mm, which is divided into five size series: 1/2 unit, 1/2 unit, 1/2 unit, 2 unit and 3 unit. The rated current of unit circuit is 400A and below. The drawer changes only in height, but its width and depth do not change. Drawers with the same functional unit have good interchangeability. Each Mcc cabinet can install up to 11 1-unit drawers or 22 1/2 drawers. The drawer unit is equipped with mechanical interlocking device, and the panel has obvious signs of opening, closing test, withdrawal and other positions. The design of this product improves the thermal capacity of the adapter and greatly reduces the additional temperature rise caused by the temperature rise of the adapter to the connector, cable head and partition. The separation between functional units and compartments is clear and reliable, and the failure of one unit will not affect the work of other units, so that the failure is limited to the minimum range. The drawer unit has a sufficient number of secondary plug-ins (32 pairs for unit 1 and above, 20 pairs for unit 1/2), which can meet the requirements of computer interface and automatic control circuit for the number of contacts. |
