AI Technical Summary
Traditional low-voltage cable trays have a fixed width, which cannot dynamically adjust the space according to changes in the number or diameter of cables, resulting in excessive cable congestion and affecting heat dissipation and signal transmission.
By pulling the handle to drive the transmission rod and gear system, the threaded rod can be adjusted to change the distance between the partitions, thereby achieving width adjustment of the adjustable low-voltage cable tray to adapt to the laying requirements of different types of cables.
It improves cable installation, avoids excessive cable congestion, and ensures effective signal transmission and heat dissipation.
