[0002] Bus duct is a power transmission trunk line used in construction projects and is a substitute for power cables. Bus duct is a closed metal device composed of copper and aluminum busbars, which is used to distribute large power to various components of the distributed system. The bus duct system is a power distribution device that efficiently transmits current and has increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects.

At this time, the connection plate 422 is limited, and the connection between the dust seat 41 and the shell 1 is realized. At this time, the heat dissipation holes can be cooled through the filter 411, ensuring the normal use of the electrical components in the bus duct. When the filter 411 is used for a long time, it is necessary to clean it to prevent dust from clogging the filter 411, and further pull the chain bead 431.
