Description

Technical Field

[0001] This utility model relates to the field of low-voltage engineering technology, specifically to a low-voltage engineering cable tray structure. Background Technology

[0002] Cable trays protect circuits located inside electrical cable trays, preventing them from being exposed to the outside and ensuring safety. They also prevent lines from dangling and falling due to gravity, which would cause inconvenience. However, existing cable trays have simple structures, generally consisting of an upper tray and a lower tray, and only have the functions of cable routing and load-bearing. Due to the different lengths of the cable bundles, long cables are usually suspended by passing through the tray or piled up inside the tray to keep the external environment tidy. Cables are prone to tangling, which can affect heat dissipation and even cause fires due to high temperatures, resulting in low safety.

[0003] To address the aforementioned technical problems, this application proposes a cable tray structure for low-voltage electrical engineering. Utility Model Content
