Description

Technical Field

[0001] This utility model relates to the field of busbar technology, specifically to a telescopic busbar that is easy to install. Background Technology

[0002] In power systems, busbar trunking, as a highly efficient and safe power transmission device, is widely used in various industrial, commercial, and public facilities. Traditional busbar trunking designs often employ fixed lengths or modular splicing to adapt to different installation requirements. However, in practical applications, this design approach presents several inconveniences. Fixed-length busbar trunking is often limited by the size and layout of the site environment during installation, making it difficult to flexibly adjust to different installation spaces. When the installation space does not match the standard length of the busbar trunking, complex cutting or splicing work is required, which not only increases the installation difficulty but may also affect the electrical performance and safety of the busbar trunking.

[0003] The busbar trunking disclosed in the patented announcement number CN209767090U uses elastic blocks to divide the internal space of the conductor trunking, allowing multiple conductors to be placed in one conductor trunking. This enables the conductor trunking to be set larger and makes use of the space in the middle of the main body, thereby improving the space utilization rate of the busbar trunking.

[0004] While the aforementioned busbar design innovatively improves space utilization through flexible blocks, allowing multiple conductors to be placed within a single conductor trough, its overall length is fixed. In actual installation, different application scenarios and environmental layouts often impose varying requirements on the busbar's length. However, because the busbar's length is not adjustable, installers must perform complex cutting or splicing work based on the site conditions, thus increasing costs and construction time.

[0005] Therefore, it is necessary to invent a telescopic busbar trunking that is easy to install to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a telescopic busbar trunking that is easy to install, so as to solve the problems in the above-mentioned technology.
