[0002] Bus duct is a channel for power conductors used in power transmission and distribution systems. It is made of metal materials, usually aluminum alloy or steel. The main function of bus duct is to concentrate and protect the main conductors of power transmission, while providing safe electrical insulation and protection. Bus duct is usually rectangular or square in cross-section and can hold multiple power conductors. They are usually installed on the walls, ceilings, basements or next to power equipment in buildings. There are brackets and partitions inside the bus duct to separate and fix the power conductors to avoid mutual interference.
