What are the uses and characteristics of dense bus ducts? Nowadays, the power system is all busbar trunking, which is a conductive material that can replace traditional cables to transmit electricity. It is composed of copper bars and an outer shell, and each copper bar has an insulating medium. And each copper bar is tightly connected to form a three-phase four wire or three-phase five wire conductor, and the shell is generally grounded. So what are the uses and characteristics of dense bus ducts? Let's learn about them together.

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 the bus duct, its current density increases, resulting in a significant reduction in product cost. 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. The dense busbar trunking adopts busbars with a large aspect ratio, which increases the heat dissipation surface of the busbar itself and directly transfers it to the shell through insulation materials, utilizing strong convective heat dissipation methods to improve its heat dissipation conditions.

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 bus ducts. Due to the low inductance of the busbar in the bus duct, its voltage loss is small, making it suitable for high current long-distance lines and increasing the voltage level at the end of the line.

The installation of dense busbar trunking can be directly connected from the transformer to the low-voltage distribution cabinet, or directly connected from the low-voltage cabinet to the distribution system as a distribution main line. Bus ducts have the advantages of small size, compact structure, high transmission current, and easy maintenance. It is used as a power supply and distribution equipment in industrial and mining areas, enterprises, and high-rise buildings, playing a role in transmission. Its voltage can reach 400V, and the rated working current is 250-6300A.
