Dense busbars are a form of electrical energy transmission using copper or aluminum bars. Do you know why dense busbars are needed? We use dense busbars because ordinary cables lack sufficient current-carrying capacity. Flat cables are insufficient to meet the current-carrying capacity requirements, hence the use of dense busbars. With the advent of modern engineering facilities and equipment, electricity consumption in various industries has rapidly increased, especially with the emergence of numerous high-rise buildings and large factories. Traditional cables, as transmission conductors, cannot meet the requirements of high-current transmission systems. The parallel use of road cables brings many inconveniences to on-site installation and connection. Dense busbars, as a new type of power distribution line, have emerged as a solution.

TQMC-L High-Density Busbar Trunking
With the advent of modern engineering facilities and equipment, electricity consumption in various industries has rapidly increased, especially with the emergence of numerous high-rise buildings and large factories. Traditional cables, as power 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, construction, and connection. Pluggable aluminum busbar trunking has emerged as a new type of power distribution line. Compared with traditional cables, it fully demonstrates its superiority in high-current transmission. At the same time, due to the adoption of new technologies and processes, aluminum busbars have been greatly reduced. The contact resistance and temperature rise at the junctions of the trough ends and branch points are reduced. Aluminum busbar trunking uses insulating materials, thereby improving the safety and reliability of the aluminum busbar trunking and making the entire system more perfect.

Fire-resistant busbar trunking consists of a shell coated with fire-retardant paint, busbars wrapped with fire-resistant mica tape, and a support made of fire-resistant insulating material. The support has multiple recesses, into which current bars are embedded and secured. A busbar junction box is located at one end of the fire-resistant busbar trunking, and another is inside the trunking. The fire-resistant busbar trunking has excellent insulation performance and can be used continuously under normal conditions and for more than 1 hour under fire conditions. It can be used in high-rise buildings and important facilities as a replacement for fire-resistant power cables used in power transmission and distribution.
