GGD series AC low voltage distribution cabinet

Product Summary

The GGD low voltage switchgear is applied in power plant, substations.industry and mine corporations, etc., with rated voltage 400V, max operating current 4000A and rated frequency 50/60Hz. lt can be applied as power conversion distribution control, distribution and control of power, lighting and power distribution, etc.The cabinet structure of GGD type adopts the form of general cabinet, the frame is assembled by local welding of cold bending section steel, so it is firm and solid. The parts of the general cabinet are designed according to the principle of module, and have the installation hole with 20mm as the module, and the common coefficient is high. lt can make the factory realize the pre production, not only shortens the production cycle,but also improves the working efficiency.

Product Features

1. The frame has sufficient strength and rigidity, Which can withstand themechanical stress and electrodynamic force generating from installation components and short circuit, At the same time it does not affect the performance of the device because of the hoisting and transportation of the device,etc.
2. When the cabinet is designed, the heat dissipation in the operation of theequipment is fully taken into account. There are different number ofradiating slots in the upper and lower ends, heat is going up when the electrical components in the cabinet are heating，and is discharged through the top slot, and the cold wind constantly from the bottom slot is supplied into the cabinet, the sealed cabinet body bottom forms a natural ventilation from bottom to top， which achieves the purpose of heat dissipation.
3. The instrument door equipped with the electrical components isconnected with the frame with many annealed copper wires. Theinstallation parts in the cabinet are connected to the frame with the knurled screws,and the whole cabinet forms a complete grounding protection circuit.
4. The cabinet cover can be removed if necessary, to facilitate the main busassembly and adjustment on site. Flying rings are provided at the fourcomers of the cabinet top for lifting and shipping.
