Fiberglass cable protection conduit (FRP cable conduit) is made of high-performance composite materials, which have four core advantages: corrosion resistance, high strength, insulation flame retardancy, and lightweight convenience. Its service life is up to 50 years, which can resist acid, alkali, salt spray and moisture erosion. The ring stiffness is ≥ 12.5kN/m ², the compressive performance is excellent, the oxygen index is ≥ 28, and the flame retardant level reaches UL94 V-0 standard, ensuring the safe operation of the cable. The product diameter covers DN50-DN300, with a pressure rating of 0.6-2.5MPa, weighing only 1/4 of steel pipes, and increasing installation efficiency by more than 60%. It is widely used in fields such as power, communication (such as 5G optical cables), and transportation (subways, highways), and is a high-quality choice that balances performance and cost-effectiveness.

Produce
1. Material preparation
Mix resin, curing agent, and glass fiber (short cut felt/continuous yarn).
2. Forming
Immersed fiber spiral winding mold (CNC controlled angle and tension)
3. Curing
Heat (60-80 ℃) or cure at room temperature for 2-8 hours.
4. Demoulding and trimming
Cut and polish the edges after demolding, and apply a protective layer if necessary.
5. Quality inspection
Test the stiffness and hardness of the testing ring, and package it after passing the inspection (4m/6m standard length).
High strength and lightweight: With a density of only 1/4 of steel pipes, it can be directly buried under the roadway without the need for a concrete protective layer, resulting in high construction efficiency.
Strong corrosion resistance: can resist acid, alkali, salt and organic solvent erosion, with an inner lining resin content of 70% -95% and a lifespan of over 50 years
Excellent electrical insulation performance: non-magnetic material, no eddy current loss, suitable for single core cable laying, ensuring safe cable operation.
Wide temperature resistance range: It can be used for a long time from -50 ℃ to 130 ℃, with frost resistance, heat resistance, and no deformation.
Smooth inner wall and low resistance: It is not easy to scratch the cable when threading, with low fluid resistance and reduced energy consumption
Application
1. Energy and electricity: urban power grid renovation, new energy power stations (photovoltaic/wind power), high-voltage transmission projects.
2. Transportation infrastructure: high-speed rail/subway tunnels, highways, and cross water projects (bridges/submarine cables).
3. Communication municipal: 5G optical cable protection, municipal power pipeline network, airport underground cables.
4. Special environment: Corrosive or complex geological areas such as chemical zones, saline alkali land, and soft soil geology.
5. Industrial facilities: sewage treatment plants, underground pipelines in densely populated areas.
