Dongguan Cable Trench Cover wholesale - sale - supplier - manufacturer [Dongguan Songshulin Environmental Protection Building Materials Co., Ltd.]
Cable trench covers are a type of cover plate, along with others like ground trench covers, drain trench covers, pond covers, etc. Unlike the other types of cover plates, cable trench covers have higher requirements for product performance and installation. They can be categorized by material into fiberglass cover plates, metal cover plates, plastic cover plates, wooden cover plates, and stone cover plates.
Cable trench cover requirements for the product:
High strength, high load-bearing capacity
Having certain strength and load-bearing capacity is the most basic requirement for sheet materials. Choose different types of materials based on the application. It's evident that wooden and plastic covers do not meet the load-bearing requirements for cable trench covers. Traditionally, cable trench covers were mainly stone or metal covers, but now there's also a glass fiber reinforced plastic cover that offers a load-bearing capacity comparable to both.
2. High safety performance
Safety performance is primarily reflected in aspects such as thermal conductivity, electrical conductivity, and toughness. Stone covers do not conduct heat or electricity but lack inherent toughness, making them as prone to damage or deformation as metal covers. Metal covers have excellent thermal conductivity and a unique electrical conductivity property. In terms of safety performance, only glass-fiber reinforced plastic (GFRP) covers meet the specified requirements, being non-conductive, non-heat-conductive, and highly tough.
3. Strong sealing performance
Encapsulation is an essential feature of cable trench covers, as only when it meets certain requirements can it better protect cables from damage. In terms of encapsulation, it is not related to the material of the product. The main thing to pay attention to is that the installation must be done strictly according to standard dimensions, angles, and load-bearing capacity.
4. Wear resistance, corrosion resistance
Cable trench covers must meet certain requirements for corrosion and wear resistance; otherwise, it can affect the sealing integrity of the cover, leading to damage to the internal cables. In terms of corrosion resistance, fiberglass covers excel, allowing for long-term use in harsh environments with strong acids, alkalis, and organic solvents.
The anti-slip treatment for cable trench covers is primarily done through patterned finishing, which is simple to produce and only requires a basic mold. In addition to patterned finishing, glass fiber reinforced plastic cable trench covers can also have two types of anti-slip treatments, similar to glass fiber reinforced plastic grating panels: internal sanding and external sanding.
Fiberglass cable trench covers: Installation precautions
1. Cut reasonably; glass fiber reinforced plastic cable trench covers are easy to cut, requiring only simple hand tools or small electric cutting tools. When cutting, ensure the cutting surface of the cover is parallel to the surface to maximize the load-bearing capacity of the glass fiber cover.
2. Assembly between lids can be achieved through special design, combining two different lids for enhanced sealing.
3. Simply perform regular inspections on the cable trench covers; no maintenance is required.
