Product Features

1.The frame has sufficient strength and rigidity, Which can withstand the mechanical stress and electrodynamic force generating frominstallation components and short circuit, At the same time it does not affect the performance of the device because of the hoistingand transportation of the device, etc.

2.When the cabinet is designed, the heat dissipation in the operation of the equipment is fully taken into account. There are differentnumber of radiating 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 sealedcabinet 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 is connected 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 completegrounding protection circuit.

4.The cabinet cover can be removed if necessary, to facilitate the main bus assembly and adjustment on site. Flying rings areprovided at the four comers of the cabinet top for lifting and shipping.

This product can use standard communication protocols to provide standard communication interfaces as needed to realize the functions of online centralized monitoring and control of power
