Bus Development History

- Nov 07, 2018 -

A busbar is a common path on which multiple devices are connected in parallel. In a computer system, it refers to a shared high-speed path on which multiple computers are connected in parallel, which can be used to transmit data between these computers, but only one device can send data at the same time.

With the emergence of modern engineering facilities and equipment, the power consumption of various industries has increased rapidly, especially the emergence of numerous high-rise buildings and large workshops. Traditional cables used as transmission lines cannot meet the requirements in high-current transmission systems. The parallel use of multiple cables brings a lot of inconvenience to the field installation and construction connection. As a new type of distribution cable, the plug-in busway has emerged as a new type of cable. Compared with the traditional cable, it fully demonstrates its superiority in high-current transmission. At the same time, it has greatly reduced the busbar due to the adoption of new technologies and processes. The contact resistance and temperature rise at the joints at the two ends of the slot and the junction of the splitter port, and the use of high-quality insulating materials in the busway, thereby improving the safety and reliability of the busway and improving the overall system.


The busway is a system consisting of a metal plate (steel plate or aluminum plate), a protective casing, a conductive row, an insulating material and related accessories. It can be made into a section of standard length, and has a plug-in junction box at intervals, or a feed-type enclosed busbar without a splitter box in the middle. Great convenience for feeding and installation.


The development of busbars in insulation has experienced three generations of air-plug busbars, densely insulated busbars and high-strength composite insulated busbars. The busway can be set with power supply conductors and protective conductors according to L+N+PE, L1+L2+L3, L1+L2+L3+N, L1+L2+L3+N+PE systems to meet the needs of power load.
