1. The assembly form of the main frame is designed into two types, the fully assembled structure and partially welded construction (side frame and beam), for users to choose.
2. The functional rooms of the device are isolated from each other. The compartments are divided into functional unit compartments, bus compartment and cable compartment.The functions of each compartment are relatively independent.
3. The horizontal main bus is arranged in the form of flat arrangement behind the cabinet to enhance the electric power of the bus, which is the basic measure to make the main circuit of the device have high short-circuit strength.
4. The design of cable compartment makes it very convenient for the cable to go in and out.
