Abstract: Super high-rise buildings generally refer to buildings with a height of more than 100 meters.They are the mainstream of modern urban construction and development.Super high-rise buildings that are safe,convenient,energysaving and comfortable are more and more favored by people.With the continuous rise of super high-rise buildings,the wiring of low-voltage Alternating current distribution system has been changed,and the branch of main line cable has developed from bus bar and puncture clamp to pre-branch cable.After the introduction of pre-branch cable technology from abroad,it not only extends and deepens the wiring mode of building cable, but also effectively improves the quality of distribution lines.Therefore,starting from the technical characteristics and application advantages of pre-branch cable,this paper discusses its application strategy in super high-rise buildings,so as to promote the improvement of electromechanical engineering quality in super high-rise buildings.
