Special attention should be paid to the selection of bus ducts in high-rise buildings. With the continuous emergence of high-rise buildings, the selection of bus ducts has attracted widespread attention in the construction industry. As for how to choose bus ducts, many companies do not know the inside story. In order to make more Many customers understand the company's products, the company uses its own hands-on practice to teach customers how to choose products!

First of all, in the power supply system of high-rise buildings, the power supply main line plays a very important role. It is like the aorta in the human body. Once it fails, it will cause serious consequences. Therefore, the production, construction and scientific research units have been working hard for the reliability of the power supply main line and continuously improving it, in order to create new products with simple installation and maintenance, high quality and low price, and stable performance. Indoor wire laying methods can be divided into: open laying-the wire is directly or in the protective body of the pipe, wire trough, etc., and is laid on the surface of the wall, ceiling, truss, bracket, etc .; Lay in the body is placed inside walls, ceilings, floors, floors, etc., or in concrete holes. For small buildings, the electrical load is not very large, and the main line often uses insulated conductors; for high-rise buildings, the electrical load is large, and using insulated conductors as the main line can no longer meet the power supply needs. At this time, the main line needs to use cables or bus ducts .

Prior to the 1980s, the mains of power supply in high-rise buildings were mainly ordinary cables with good reliability, and the cables were laid along the walls in electrical shafts with cables or cable trays. As a power supply trunk cable, the cable is much safer and more reliable than bare wires and bare bars, but the current carrying capacity is limited, the cross section of the cable cannot be made very large (the maximum can only be 400mm2), and the cable is too thick, which makes construction on the site difficult. In the mid-to-late 1980s, the city developed rapidly, and high-rise and super-high-rise buildings were built in large numbers. The electrical load of buildings increased sharply, and the limitations of cables as power supply trunks became more and more prominent, especially the technical difficulty of making cable branch joints on site. There is an urgent need for a large-capacity, convenient branching power supply trunk line to replace it. At this time, the bus duct with large capacity and convenient branching was introduced from abroad, and it was quickly popularized and applied in the project.
