1. Cement cover
Cement cover is more common, because the underground passage cover made of cement material is relatively solid and has strong bearing capacity. Therefore, if heavy objects often pass through the cable trench cover, the cement cover is more suitable. Although the cable trench cover is made of cement, its appearance is not as good as other materials.
2. Phenolic composite material
Phenolic composite material has excellent and stable performance, which is very suitable for manufacturing cable trench cover. For example, the hardness of this material is not lower than that of the cover plate made of cement and phenolic composite material, the oxygen index is low, it is not easy to extinguish, and it has certain fire-retardant functions.
Three, composite materials
In fact, if used in tunnels, a cable trench cover made of composite wood is suitable. The appearance of composite materials is natural and beautiful, which is different from ordinary materials. The composite material is insect-resistant and wear-resistant, and various functions have been improved.
Four, polyester fiber
Polyester fiber is a chemically differentiated material. Like polyethylene, it is made by chemical polymerization. This polymer material has stable and excellent performance, is not easy to corrode and age when placed in a tunnel, and its service life is greatly improved. At the same time, the material not only wins in function, but also provides more convenience for the usual cleaning and maintenance of the cable trench cover, and the dirt on it can also be easily wiped off.
