The busway is a closed metal device composed of copper and aluminum busbars, which is used to distribute large power to each element of the dispersion system. Electric wires and cables have been increasingly replaced in indoor low-voltage power transmission trunk projects.
It has been popularized in developed countries abroad, as well as in Hong Kong, China, and Macau, China. In Guangzhou, Guangdong, my country, where the power distribution room of the building above 12 floors is out of the line, that is, more than 90% of the main lines leading to the floor use the bus duct; the 630KVA transformer to the power distribution cabinet must use the bus duct.
