GANGTAI DONGHONG-BUSWAY/BUS DUCT/CUSTOMIZED

2023-08-30

The bus duct is a new circuit method developed by the united states and called "bus-way-system". It uses copper or aluminum as a conductor, is supported by non-olefinic insulation, and is then assembled into a metal groove to form new conductors. The real practical application in japan was in showa 29 (ie 1954), and the busway has been developed since then. Nowadays, it has become an indispensable wiring method in electrical equipment and power systems such as high-rise buildings and factories.
Due to the needs of various buildings such as buildings and factories, and this demand has a trend of increasing year by year, the use of the original circuit wiring method, that is, the pipe-through method, brings many difficulties during construction, and when the power distribution system needs to be changed. , it is almost impossible to make it simpler, however, if the busway is used, it is very easy to achieve the purpose, and it can also make the building more beautiful.
From an economical point of view, the busbar itself is more expensive than the cable, but compared with the various accessories for wiring and the entire power system, the use of the busbar can make the construction cost much cheaper (please see the diagram) , especially in the case of large current capacity, this situation is more obvious. With the emergence of modern engineering facilities and equipment, the power consumption of all walks of life has increased rapidly, especially the emergence of many high-rise buildings and large workshops. The parallel use of multiple cables brings a lot of inconvenience to the on-site installation and construction connection. The plug-in bus duct emerges as a new type of distribution wire. Compared with the traditional cable, the bus duct fully reflects its superiority in the transmission of large currents. The contact resistance and temperature rise at the connection between the two ends of the busbar and the insertion point of the branch port, and high-quality insulating materials are used in the busbar, thereby improving the safety and reliability of the busbar and making the whole system more perfect. 

The busway is characterized by series 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. Busway products are suitable for three-phase four-wire, three-phase five-wire power supply and distribution system engineering with ac 50hz, rated voltage 380v, rated current 250a-6300a. The closed busway (referred to as the busway) is a busbar system composed of a metal plate (steel plate or aluminum plate) as a protective shell, conductive bars, insulating materials and related accessories. It can be made into a plug-in closed busbar with a plug-in junction box at intervals, and can also be made into a feed-type closed busbar without a junction box in the middle. In the power supply system of high-rise buildings, power and lighting lines are often set separately, and the bus duct is installed vertically along the wall in the electrical shaft as the main power supply line one or more times. According to the purpose, a busway is generally composed of the starting busway, the straight-through busway (with jacks and without jacks), l-type vertical (horizontal) bend-through bus, z-type vertical (horizontal) offset bus, t-type vertical (horizontal) offset bus, t type vertical (horizontal) three-way bus, x-type vertical (horizontal) four-way bus, variable capacity busway, expansion busway, terminal head, terminal junction box, plug-in box, busway related accessories and fastening devices, etc. .
According to the insulation method, the busway can be divided into three types: Air type plug-in busway, dense insulation plug-in busway and high-strength plug-in busway. According to its structure and use, it is divided into dense insulation, air insulation, air supplementary insulation, fire resistance, resin insulation and sliding contact busway; according to its shell material, it is divided into steel shell, aluminum alloy shell and steel-aluminum mixed shell busway. Strong anti-corrosion performance
After anodizing for 10u, the aluminum profile shell has much better anti-corrosion performance. Compared with the steel shell, japan's long-term atmospheric exposure test on different grades of aluminum alloy sheets and galvanized copper sheets shows that the corrosion depth of the former is about 20 times that of the latter. One.
Reliable insulation
There is an insulating layer on the conductive bar, there is a certain air gap between the phases, and there are insulating pads pressed by dmc material between the conductive bar and the shell, triple insulation, to ensure that the insulation of the busbar is foolproof, especially in a humid environment. Show its superiority.
