TECHNICAL CHARACTERISTICS
• The cabinet adopts common cabinet form, with frame of 8 MF local welding assembled cold bending section steel, with 20 mounting holes, and the general coefficient is high. 
• Considering the heat dissipation problems in equipment operation, there are several radiating slots on the upper and lower ends of the cabinet, the heat rises when the electrical components in the cabinet are heated , then it discharges through the top slot. And the cold air adds into the ark constantly through the bottom slot, which forms a natural air duct to achieve the goal of heat dissipation. 
• The GGD cabinet is designed according to the modern industrial product shape, using the golden ratio design method of the cabinet body and cut size of each part, making the cabinet beautiful and novel. 
The roof of the cabinet can be disassembled in case of need to make it convenient for the assembling and adjustment of the main bus- bar on the scene. There are four angle rings on the top of the cabinet, which is used for lifting and shipment.
The protection grade of the cabinet is IP30, also it can be produced according to customer's requirements.
