Description

Technical Field

[0001] The utility model relates to the technical field of bus ducts, in particular to a bus duct connection device. Background Art

[0002] Bus duct is a closed metal device composed of copper and aluminum busbars. It is used to distribute large power to various components of the distributed system. It has increasingly replaced wires and cables in indoor low-voltage power transmission trunk projects. Plug-in bus duct has emerged as a new type of distribution conductor. Compared with traditional cables, it fully demonstrates its superiority in large current transmission. At the same time, due to the use of new technologies and new processes, the contact resistance and temperature rise at the connection points at both ends of the bus duct and the branch port plug-in points are greatly reduced, and high-quality insulating materials are used in the bus duct, thereby improving the safety and reliability of the bus duct and making the entire system more perfect. When the bus duct is installed and used, sometimes the distance is insufficient, so it is necessary to connect two sets of bus ducts in parallel.
