(Summary description)1, functional aspects The busbar is made of copper or aluminum. It has high current density, small resistance and small skin effect. It does not need to be derated. A small voltage drop means that the energy loss is small, and the user's capital contribution is saved. As far as the cable is concerned, since the cable core is a plurality of thin copper wires, the root area is larger than that of the bus bar of the same current level. Moreover, its "skin effect" is severe, reducing the extra value of the current, adding a voltage drop, and simply heating up. The energy of the line is lost and aging.

Information
1, functional aspects
 
The busbar is made of copper or aluminum. It has high current density, small resistance and small skin effect. It does not need to be derated. A small voltage drop means that the energy loss is small, and the user's capital contribution is saved. As far as the cable is concerned, since the cable core is a plurality of thin copper wires, the root area is larger than that of the bus bar of the same current level. Moreover, its "skin effect" is severe, reducing the extra value of the current, adding a voltage drop, and simply heating up. The energy of the line is lost and aging.
 
2, equipment aspects
 
The busbar is made up of many segments, each of which is short and light in length. Therefore, the device only needs a small number of people to complete the activity. The busbar has a number of standardized parts and stocks that can be shipped quickly to save time on site. Its tight "sandwich" program can reduce electrical space and then free up more space for commercial use, such as renting or as a public place. As far as equipment cables are concerned, it is a difficult job. Because a single cable is usually very heavy, the equipment operation requires the cooperation of many people, and it takes more time to complete. In addition, due to the tortuous radius of the cable, more equipment space is required.
 
3, line optimization
 
By using the busway, we can swallow some branch circuits and convert them into a large busway using the box. It simplifies the electrical system and results in lower current values ​​for more strands. This saves the cost of the project and is easy to maintain. With regard to the traditional cable lines, the cables make the electrical system extremely messy, infinite and difficult to maintain, thus wasting engineering costs and equipment space.
