Technical Features

★ The cabinet adopts a universal structure. The frame is assembled by partial welding of 8MF cold-formed steel sections. Parts and components are designed based on the modular principle with 20-module mounting holes, featuring high universality.

★ Full consideration is given to heat dissipation during operation. The cabinet is equipped with different numbers of heat dissipation holes at the upper and lower ends. Heat generated by components rises and discharges through the upper slots, while cool air is supplied through the lower slots, forming a natural ventilation channel from bottom to top inside the enclosed cabinet for effective heat dissipation.

★ The cabinet finish features high adhesion and good texture with a matte color, avoiding glare and providing a comfortable visual environment for operators on duty.

★ The top cover of the cabinet can be removed when necessary, facilitating the installation and adjustment of the main busbar on site.

★ The dimensions of each part are designed using the golden ratio, making the whole cabinet elegant and innovative in appearance.

★ The protection degree of the cabinet is IP30. It can also be selected between IP20 and IP40 according to customer requirements.
