Description

Technical Field

[0001] This utility model relates to the field of cable trench technology, and in particular to a cable trench assembly. Background Technology

[0002] Cable trench assemblies are a key component of power facilities and belong to the underground protection system in the field of power engineering technology. They typically consist of modules such as the trench body, cover plate, shielding plate, and supports, and are equipped with sealing devices to prevent rainwater and impurities from entering. Employing prefabricated or assembled designs, they are easy to install and structurally stable, facilitating cable laying and maintenance. Widely used in urban power grids, substations, and other scenarios, they effectively protect cables from external damage and ensure stable and reliable power transmission.

[0003] In existing cable trench assemblies, rainwater can easily seep into the cable trench through the gaps between the cover plates, causing surface corrosion. Furthermore, cables within the trench can easily cross and overlap, leading to electromagnetic interference. To overcome these disadvantages, this invention provides a cable trench assembly.
