Introduction to the Characteristics of FRP Cable Ducts
Release time:
2019/12/13
The fiberglass cable conduit is suitable for the protective conduits of power and communication cables laid in various environments. It is especially effective in special environments such as when cables pass through traffic intersections and cross rivers or bridges, showcasing its advantages of easy construction and high strength. It is widely used in the construction of infrastructure in fields such as power, communications, transportation, and civil aviation airports. So, what excellent characteristics does the fiberglass cable conduit have? Here are some specific introductions: 1. Good electrical insulation performance: The fiberglass cable conduit is made of non-magnetic material, which has no eddy current loss and electrical corrosion, thus saving energy and is suitable for single-core cable laying; it has a large current-carrying capacity and low thermal resistance, ensuring the normal operation of the cables.
Fiberglass cable conduits are suitable for the protective conduits of power and communication cables laid in various environments. Especially in special environments such as cables passing through traffic intersections and crossing rivers or bridges, their superior performance in terms of ease of construction and high strength is fully demonstrated, and they are widely used in the construction fields of power, communication, transportation, and civil aviation airports.
So what excellent characteristics do fiberglass cable conduits have? Let's introduce them in detail below:
1. Good electrical insulation performance: Fiberglass cable conduits are made of non-magnetic materials, with no eddy current loss and electrical corrosion, energy-saving, suitable for single-core cable laying; they have a large current-carrying capacity, low thermal resistance, and do not adversely affect the normal operation of the cables.
2. Corrosion resistance: Fiberglass cable conduits are specially designed to resist the erosion of many chemical fluids such as acids, alkalis, salts, untreated sewage, corrosive soil, and groundwater. They can be used in high-temperature saline-alkali areas.
3. Wide range of applications: Fiberglass cable conduits are suitable for use as protective conduits for power and communication cables when buried underground, as well as for special environments such as direct burial across traffic lanes or laying at traffic intersections, and for crossing bridges and rivers; they are used in power grid construction and renovation, urban municipal renovation, civil aviation airport engineering construction, industrial parks, community projects, and transportation bridge engineering construction. They can be used in conjunction with various specialized accessories to form multi-layer and multi-column cable conduit systems according to different project requirements.
4. Long service life: Fiberglass cable conduits have a longer service life than traditional protective conduits, with a designed service life of50years.
5. High smoothness: The inner wall of fiberglass cable conduits is smooth, without burrs, making cable threading easy without scratching the cables.
6. High strength: Fiberglass cable conduits can be directly buried under traffic lanes without the need for a concrete protective layer, which can accelerate the construction progress of cable projects and reduce construction costs.
7. Flexible system with good adaptability: Fiberglass cable conduits are flexible, and when paired with flexible joints, they can withstand external pressure and damage caused by foundation settlement.
8. Flame retardant, heat-resistant, and frost-resistant: Fiberglass cable protection conduits can be used long-term at temperatures from-50°C to130°C without deformation.
9. Quick and convenient installation: The weight of fiberglass cable protection conduits is only about1/4of steel pipes and about1/10of concrete pipes, making transportation and installation simple and convenient. The installation of fiberglass cable protection conduits mainly adopts the “O” type sealing ring socket connection method, with rubber sealing rings used at the connection joints to adapt to thermal expansion and contraction, and to prevent sand and mud from entering; flanges or bonding methods can also be used for connections in special locations.
