Product introduction

GGD type AC low-voltage distribution cabinet is suitable for AC 50Hz distribution systems with rated operating current up to 3150A for power users such as power plants, substations, factories and mining enterprises, and is used for power conversion, distribution and control of power, lighting and distribution equipment.

Structural features

1 The cabinet body of the GGD type AC low-voltage distribution cabinet adopts the form of a general cabinet. The frame is made of partially welded 8MF cold-formed steel. The frame parts and special supporting parts are supplied by the designated steel manufacturer to ensure the accuracy and quality of the cabinet body.

2 The design of GGD cabinet takes full consideration of the heat dissipation problem during cabinet operation.

3. The cabinet door is connected to the frame with a rotating shaft-type movable hinge, which is easy to install and disassemble. A mountain-shaped rubber plastic strip is embedded in the folded edge of the door. When the door is closed, the strip between the frame and the frame has a certain compression stroke, which can prevent the door from directly colliding with the cabinet body, and also improves the door's protection level.

4. The instrument door equipped with electrical components is connected to the frame with multiple strands of soft copper wire, and the entire cabinet forms a complete grounding protection circuit.

5. The cabinet surface paint is made of polyester orange baking paint, which has strong adhesion and good texture.
