What is a bus duct? What are the characteristics of a dense bus duct? Bus duct is an effective distribution device for transporting current. It is a new type of conductor formed by using copper or aluminum as a conductor, supporting it with non vinyl insulation, and then installing it into a metal duct. Especially adapted to the needs of increasingly tall buildings and large-scale factories for economically reasonable wiring. Modern high-rise buildings and large workshops require enormous amounts of electrical energy, and in the face of this massive load that requires hundreds or thousands of amperes of strong current, safe and reliable conduction equipment must be selected. Bus ducts are a good choice.



As a current distribution device, dense busbar trunking must have certain requirements. In order to ensure the normal operation of busbar equipment, busbar trunking devices must be properly installed. It can be directly connected from the low-voltage cabinet to the distribution system as a distribution main line. It has the advantages of small size, compact structure, high transmission current, and easy maintenance. So what are the characteristics of dense bus ducts?

1. The fixing method of dense bus duct is supported by a strong metal shell, which can withstand the stability under large electric force impact. Due to strong mechanical stress, it can be used to adopt busbars with a large aspect ratio and arranged vertically.
2. Due to the high current carrying capacity of dense busbars, their current density increases, resulting in a significant reduction in product costs. The structure of the busbar connection and socket of the dense bus duct is more complex, the manufacturing difficulty is increased, and the production process cost is high.
3. It adopts a busbar with a large width to thickness ratio, which increases the heat dissipation surface of the busbar itself and directly transfers it to the shell through insulation material. It utilizes a strong convective heat dissipation method, making its heat dissipation conditions better.
4. Due to the application of busbars with a large aspect ratio, their heat generation is small while their heat dissipation capacity is large. Therefore, the current carrying capacity is greatly increased, making it suitable for high current busbars.
5. Copper with a large aspect ratio is used for dense busbars. The impedance of busbars in dense busbars is very small, so their voltage loss is small. It is suitable for high current long-distance lines and can improve the voltage level at the end of the line.
Dense busbar trunking plays a very important role in power systems, especially in power supply and distribution equipment in industrial and mining areas, enterprises, and high-rise buildings, where it plays a transmission role with a voltage of 400V and a rated working current of 250-6300A, playing a significant role in these enterprises. In buildings, workshops, and other places where cables were used in the past, bus ducts could be used for replacement, and dense busbars could be used instead of traditional cables.
