Bus ducts have been developed in China for half a century. Since the 1980s, bus ducts have been used in various places to replace cables, mainly because they have more advantages than cables. Compared with cables, The advantages and disadvantages are simply the differences between trunk-type power supply and radial power supply.

Bus ducts have been developed in China for half a century. Since the 1980s, bus ducts have been used in various places to replace cables, mainly because they have more advantages than cables. Compared with cables, The advantages and disadvantages are, in short, the difference between trunk-type power supply and radial power supply. The results of the national supervision and random inspection in 1995 and 2000 showed that the qualified rate of domestic busway increased from 57.14% to 71.4%, which laid the foundation for the widespread application of busway A solid foundation, current busbar welding technology: L-shaped (flat bend) and T-shaped busbars are all welded using busbars. At present, there is no relevant standard for national standards. It is said that welding flaw detection is being considered, (according to GB3323 Class III standard), high-tech bus ducts already have a high protection level of IP54 or higher, which solves the waterproof problem.
