What is the difference between intensive bus duct and closed bus duct
Dense bus duct, a kind of closed bus duct. At present, the bus bar bridge is divided into several generations. The first generation is called bus duct and the second generation is called bus duct. All bus duct are closed, including dense bus duct, air bus duct, fire safety bus duct, fire prevention bus duct, pouring bus duct and so on.
Dense busbar, also known as closed busbar, is a closed busbar, but it is not only dense busbar, such as gas busbar is closed busbar. There are many kinds of closed busbar, mainly dense busbar and air type closed busbar. All of these belong to the closed bus duct, because they are all enclosed with electrical conductors inside and insulated from the outside. In view of the subtle differences between them, there must be some. In fact, we can find a bus duct manufacturer to consult.
According to the above, the category of closed busbar duct is relatively wide, including dense busbar duct, which is only one kind of busbar duct.
Let's take a look at how the technical department of bus duct explains it;
Dense bus duct is a kind of bus duct. Both of them are closed bus bars. Only the dense bus bar processing technology is relatively close, and the dense bus bar is a kind of forming bus bar that the manufacturer has already done. Generally, it only needs to be downloaded.
The closed busbar duct (commonly known as busbar duct) is a busbar system software, which is made of metal sheet (thick steel plate or aluminum alloy plate) as the maintenance casing. Conductivity row. Composition of insulation materials and related accessories. This product can be made into a plug-in closed bus duct with too large intervals, or an explosion-proof switch-type closed bus duct without a distribution box in the middle. In the distribution lines of towering buildings, cable lines and lighting lamp routes are often set separately, and bus ducts are installed once or several times vertically on the inner edge wall of the electrical shaft as the main line of power engineering. The type of busway for a trip generally consists of the beginning busway. L-type vertical (horizontal) bent through busbar. T-type vertical (horizontal) bent through busbar. Z-type vertical (horizontal) bent through busbar. Type T vertical (horizontal) reference point bus. T-type vertical (horizontal) tee line. T-type vertical (horizontal) tee line. T-type vertical (horizontal) tee line. X-type vertical (horizontal) tee line. T-type vertical (horizontal) tee wire. According to the insulation layer method, the bus duct can be divided into three types: gas insertion bus duct, dense insulation layer insertion bus duct, and high toughness insertion bus duct.
Dense bus duct its waterproof. Poor heat removal capacity. In terms of waterproofing, the bus is easy to return to moisture and leakage during the construction process, resulting in a reduction in the two-color grounding resistance. The heat dissipation of the bus mainly depends on the casing, because the line is closely arranged with the middle of the line, L2. The heat release rate of the L3 phase is relatively slow, resulting in a rise in the temperature of the busbar. The connection slot of the compactness type insulation layer is limited by the shell plate, and only the horizontal section not exceeding 3m is manufactured. Since the two-color magnetic density of the bus bar is not large, the bus bar can cause a strong electric driving force under a large current, which promotes the accumulation of magnetic oscillation frequency meters and causes noise. The plug-in bus duct is a tree bar system software, small in size, compact in structure and reliable in work. Large transportation current. Very easy to tap explosion-proof switch. Maintenance is convenient. Low energy consumption, good dynamic heat resistance and other characteristics, is widely used in multi-storey buildings.
Generally speaking, the dense wire trough belongs to the closed bus, but the dense wire trough is more prominent. Compact structure. Reliable at work. Large transportation current. Conducive to explosion-proof switch. Maintenance is convenient. Low energy consumption. Good heat resistance and other advantages.
