Nine low-voltage switch cabinets of the GGD type and one American-style transformer from Mongolia are about to be completed.

Ggd AC Low-Voltage Distribution Cabinet

The GGD is a widely used fixed-type AC low-voltage distribution cabinet in China. Its model designation indicates: "G" for AC low-voltage distribution cabinet, "G" for fixed mounting and wiring of components, and "D" for power use. The numbers 1, 2, and 3 represent breaking capacities of 15kA, 30kA, and 50kA respectively.

Key technical parameters include a rated voltage of 380V, rated current from 100A to 3150A, and short-time withstand current from 15kA to 50kA. The cabinet body is constructed from 8MF cold-rolled steel with 20mm mounting holes, offering high component interchangeability. Natural ventilation through top and bottom slots ensures effective heat dissipation without fans.

Designed for indoor use, it operates within -5°C to +40°C and at altitudes below 2000m, with a standard protection rating of IP30. GGD cabinets are widely applied in power plants, Substations, and industrial enterprises for power distribution, lighting, and energy conversion, particularly suitable for transformers below 2000kVA.
