[0002] With the emergence of modern engineering facilities and equipment, the electricity consumption of all walks of life has increased rapidly, especially the emergence of numerous high-rise buildings and large factories and workshops. Traditional cables as transmission conductors can no longer meet the requirements in large current transmission systems. The parallel use of multiple cables has brought many inconveniences to on-site installation and construction. Busbar bridge is a new type of distribution conductor application. Compared with traditional cables, it fully demonstrates its superiority in large current transmission. At the same time, due to the use of new technologies and new processes, the contact resistance and temperature rise of the connection at both ends of the bus duct and the branch port connection are greatly reduced.

[0003] A Chinese patent with announcement number CN210092810U discloses a solid support structure for a cable bus duct bridge. The cable bus duct is limited and fixed by pushing the L-shaped fixing plate through the structure in the slide groove. The operation is simple and convenient to use. The bridge base is fixed to the roof by bolts and fixing blocks, so that the position of the cable bus duct can be fixed during laying and construction. At the same time, the rotating bracket can adjust the fixed position, so as to adjust the fixed height of the entire support structure. In addition, the rubber pad can increase the friction with the surface of the cable bus duct, thereby improving the stability during limit fixation.
