Aluminum busbars are systems composed of metal plates (steel or aluminum plates) as protective shells, conductors, insulating materials, and related accessories. They can be manufactured as standard length segmented plug-in junction boxes, or as feed-through enclosed aluminum busbars without intermediate junction boxes, providing convenience for power supply, installation, and maintenance. Aluminum busbar troughs have evolved in insulation methods, progressing from air-plug aluminum busbar troughs, air-tight insulated plug aluminum busbar troughs, to high-strength composite insulated plug aluminum busbar troughs. Aluminum busbars have high current density, low resistance, low skin effect, and do not require capacity reduction. They have low voltage drop, low energy loss, and save users investment.
An aluminum busbar is a shared path where multiple devices connect in parallel branches. In a computer system, it's a shared high-speed path connecting multiple computers in parallel, used for data transmission between these computers, but only one device can send data at a time.
With the emergence of modern engineering facilities and equipment, electricity consumption in various industries has rapidly increased, especially with the rise of numerous high-rise buildings and large factories. Traditional cables, as transmission conductors, can no longer meet the requirements of high-current transmission systems. The parallel use of multiple cables brings many inconveniences to on-site installation and connection. Pluggable aluminum busbar trunking has emerged as a new type of power distribution line. Compared to traditional cables, it fully demonstrates its superiority in high-current transmission. Simultaneously, due to the adoption of new technologies and processes, aluminum busbars significantly reduce contact resistance and temperature rise at the connection points between the trunking ends and branch points. The use of insulating materials enhances the safety and reliability of aluminum busbars, making the entire system more robust.
An aluminum busbar consists of a system composed of a metal plate (steel or aluminum plate) as a protective shell, conductive bars, insulating materials, and related accessories. It can be made into standard-length segmented, insertable junction boxes or as a feed-through enclosed aluminum busbar without intermediate junction boxes, providing convenience for power supply, installation, and maintenance.
Aluminum busbar trunking has evolved in insulation methods, progressing through air-plugged busbar trunking, airtight insulated-plug busbar trunking, and high-strength composite insulated-plug busbar trunking.
Aluminum busbars have high current density, low resistance, and low skin effect, eliminating the need for capacity reduction. They exhibit low voltage drop and minimal energy loss, saving users investment. For cables, due to the multi-strand fine copper wire cores, the root area is larger than that of an aluminum busbar with the same current rating. Furthermore, their“skin effect” is significant, reducing the rated current, increasing the voltage drop, and making them prone to overheating. Line energy losses are substantial, leading to easier aging.
The metal casing of aluminum busbar trunking protects the busbars from mechanical damage or animal harm. Installing plugins in the power distribution system is safe. The casing can be grounded as a whole, providing reliable grounding. Cables,with their PVC sheaths, are susceptible to mechanical damage; the power must be switched off when installing cables. If problems occur, it can be very dangerous.
