Functional unit

GGD type AC low-voltage distribution cabinet adopts the general cabinet configuration form, and the frame is made of 8MF cold-formed steel partially welded and assembled, and has 20 mold mounting holes, with high general coefficient.GGD AC low-voltage distribution cabinet fully considers the heat dissipation problem in the operation of the cabinet. There are different number of heat dissipation slots at the upper and lower ends of the cabinet to form a natural ventilation channel from the top to the bottom of the sealed cabinet to achieve the purpose of heat dissipation.The instrument door with electrical components is connected to the frame with multi-strand copper flexible wires, and the mounting parts in the cabinet are connected to the frame with knurled screws. The whole cabinet forms a complete grounding protection circuit.The surface of the cabinet adopts electrostatic spray molding technology, with strong adhesion and good texture. The whole cabinet is in matt color, avoiding dazzling effect.The protection level of the cabinet is IP30.
