[0002] With the emergence of modern engineering facilities and equipment, electricity consumption in all industries has increased rapidly, especially with the construction 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 has brought many inconveniences to on-site installation and construction. Busbar trunking, as a new type of power distribution conductor, has emerged. It is a closed metal device composed of copper and aluminum busbar columns, used to distribute larger power to various components of a distributed system. It has increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects.

[0003] Traditional cable busbars are often connected by bolts. When connecting them, the two sets of threaded holes need to be aligned first, and then the bolts are used to connect them. This requires tools and takes a lot of time to disassemble and assemble, making it cumbersome, inconvenient to replace, and labor-intensive.

[0004] Based on this, a modular busbar trunking system is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content
