Technical Field

[0001] The utility model relates to the technical field of busbar power distribution, in particular to an improved busbar duct with stable connection. Background Art

[0002] Modern high-rise buildings and large workshops often require huge amounts of electrical energy. In the face of the powerful current of hundreds or thousands of amperes required by this huge load, safe and reliable conduction equipment must be selected. The bus duct is a power distribution device that efficiently transmits current. The 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 line projects. However, due to the limited length of a single bus duct, it is necessary to connect multiple bus ducts when laying the bus duct. In the prior art, the connection method for adjacent bus ducts is generally welding or gluing. This connection method is not convenient for installation on the one hand, and is not convenient for later maintenance and replacement on the other hand. Utility Model Content
