Description

[0001] The utility model belongs to the technical field of electrical components, and in particular relates to a bus duct. Background Art

[0002] The cable duct is a busbar system composed of a metal plate as a protective casing, conductive bars, insulating materials and related accessories. It is used to distribute higher power to various components of the distributed system. It has increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects.

[0003] At present, the side panels of bus ducts on the market are connected with upper and lower covers by manual assembly screws, which require pre-drilling of screw holes. During assembly, in order to avoid that after one end of the side panel is fixed, the screw holes at the other end cannot accurately align with the upper and lower covers, it is necessary to align the holes at the same time, and then use screws to position and fix them at the same time. Although this assembly is convenient for subsequent disassembly and assembly, the installation operation is troublesome and consumes more man-hours. Therefore, we have specially designed a bus duct.
