In engineering structures such as power transmission and communication systems, super large bending moment poles are gradually replacing traditional angle iron towers or steel pipe poles due to their superior mechanical properties.
Prefabricated lightweight cable trenches are widely used in urban infrastructure construction due to their rapid construction and controllable quality.
Sealing elements such as sealing strips or gaskets should also be made of materials with excellent weather resistance and aging resistance, such as silicone rubber or EPDM rubber, to adapt to various harsh environmental conditions.
Prefabricated lightweight cable wells utilize factory production and rapid on-site assembly, with "simple assembly" being one of their significant advantages, playing a positive and far-reaching role in shortening the overall construction period.
Main distribution network prefabricated covers are exposed to complex and harsh outdoor environments for extended periods—enduring repeated vehicle traffic, rain erosion, UV radiation, freeze-thaw cycles, and chemical contaminants.
In modern urban infrastructure construction, cables for systems such as power, communication, monitoring, and intelligent transportation are like the "nerves" of the city, while cable trenches carrying these cables are the "vascular channels" ensuring the
