Features：

1. The frame has sufficient strength and rigidity,Which can withstand themechanical stress and electrodynamicsforce 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.
