Modern high-rise buildings and large workshops require huge amounts of electrical energy, and the powerful currents required for hundreds of amps in the face of this huge load require safe and reliable conduction equipment. The busbar system will be your ideal choice. The busway system is a power distribution device that efficiently delivers current, especially to meet the needs of increasingly high-cost buildings and large-scale factory economical wiring.
The busway features a series of matching, commercial production, small size, large capacity, short design and construction period, convenient assembly and disassembly, no burning, safe and reliable, and long service life. The busway products are suitable for three-phase four-wire, three-phase four-wire power supply and distribution system engineering with AC 50Hz, rated voltage 380V and rated current 250A-4000A.
The busway is used in low-voltage power supply systems, such as factory buildings, large commercial supermarkets, shipyards, coal mines, power plants, etc. In recent years, the use of high-rise residential quarters is increasing! The future community does not see the same wires as transformers and spiders. Instead, the power distribution room and the busbar power supply system are replaced. The trunk power supply of the cable is also replaced by the busbar radial power supply. The demand for the busway is getting bigger and bigger, which is an inevitable trend!
In the power supply system, especially in the power supply system of high-rise buildings, the power supply trunk line plays a very important role. It resembles the aorta in the human body, and once it fails, it will have serious consequences. Therefore, the production, construction and scientific research units have been making efforts for the reliability of the main power supply line, and constantly improve, in order to create new products with simple installation and maintenance, high quality and low price, and stable performance.
The indoor wire laying method can be divided into: Mingshi--the wire is directly or in the protection body of the pipe, the wire trough, etc., laid on the surface of the wall, the ceiling and the truss, the bracket, etc.; PCB design logistics software dark--the wire is in the pipe In the protective body such as the wire trough, it is laid inside the wall, ceiling, floor and floor, or in the hole of the concrete slab. For small buildings, the electrical load is not very large, the main line often uses insulated wires; for high-rise buildings, the electrical load is large, and the insulated wires are used as the main line, which can not meet the power supply needs. At this time, the main line needs cables or busbars. .
Before the 1980s, the main power supply lines in high-rise buildings mainly used universal cables with better reliability. The cables were laid in the electrical shafts along the walls with brackets or cable trays. As the power supply mains cable, the cable is much safer and more reliable than the bare wire and bare row, but the current carrying capacity is limited, the cable cross section cannot be made very large (the maximum can only be 400mm2), and the cable is too thick, and the construction on site is difficult. In the mid-to-late 1980s, the city developed rapidly, and high-rise buildings and super high-rise buildings were built in large numbers. The power load of buildings increased sharply. The limitations of cables as power supply trunk lines became more and more prominent. Especially, the technology of making cable branch joints on site was very difficult. There is an urgent need for a power supply trunk line with large capacity and convenient branching. At this time, busbars with large capacity and convenient branching were introduced from abroad. After more than 20 years of development, the busway technology has been quite mature, the maximum current can reach 5000A, and the busway can reserve the socket at any position, and the branch is convenient. Therefore, it has been rapidly promoted and applied in engineering.
In summary, the plug-in busway has the advantages of small size, compact structure, reliable operation, large transmission current, convenient tapping and feeding, convenient maintenance, low energy consumption, good dynamic thermal stability and long service life.
