The sheathed cable protection tube is a pipe made by using resin as the matrix and continuous glass fiber and its fabric as reinforcing materials, formed through computer-controlled winding or pull-winding processes. It is highly utilized in cable laying due to its notable advantages, such as high strength, corrosion resistance, and a smooth inner wall that does not scratch the cables.

I. Product Features:

1. High strength, suitable for direct burial under traffic lanes without the need for concrete protection layer, thus accelerating the progress of construction projects.

2. Excellent resilience, capable of withstanding external heavy pressure and foundation settlement-induced damage.

3. Excellent electrical insulation, flame retardant, and heat-resistant properties; can be used at high temperatures of up to 130 degrees Celsius for long periods without deforming.

4. Corrosion-resistant with a long service life, it can withstand the erosion of various corrosive mediums such as acids, alkalis, salts, and organic solvents, with a lifespan up to 50 years.

5. Interior wall smooth, no damage to cables. Rubber seal ring for push-in connection, easy to install and connect, and adapts to thermal expansion and contraction.

6. Lightweight and compact, easily carried by one person and installed by two, significantly reducing construction time and installation costs. It also avoids the issues of prolonged road excavation and disruption of urban traffic flow.

7. Non-electrolytic corrosion, non-magnetic. Unlike steel pipes and other magnetic materials, it does not generate eddy currents that cause cables to heat up and deteriorate.

Section II: Structural Features:

(1) Possesses excellent corrosion resistance; does not require cathodic protection or other corrosion prevention measures, and will not cause secondary pollution to water and other media. The product has a long service life.

(2) Lightweight, the pipe's weight is only 1/4 of the same size and length ductile iron pipe, and 1/10 of cement pipe. Easy for transportation, loading, and unloading, as well as installation.

(3) Longer pipeline length per piece reduces joints, speeding up installation and improving overall pipeline quality.

(4) The inner wall of the pipe is smooth, reducing flow resistance, improving flow velocity, and lowering energy consumption. Using a smaller diameter pipe to convey the same volume of fluid can increase the flow rate by about 10% compared to pipes of the same specification; it does not scale and maintains flow velocity over long-term use. It also provides good protection for cables in corrosive environments.



I. Product Introduction: Woven Spiral Cable Conduit

1. BWFRP fiber-woven pull-wound pipes are made from high-performance fiber-reinforced composites, epoxy resins, and unsaturated pull-wound resins. They are formed by interlaced weaving and pulling in both lateral and longitudinal directions, consisting of a textile layer, a middle layer, and an outer woven layer. This new cable power protection pipe product offers superior advantages over traditional winding pipes, effectively safeguarding cables from damage.

2. Glass Fiber Reinforced Plastic (GFRP) woven pultruded pipes, due to their unique production process, cannot easily adjust process parameters during production to change the wall thickness, thereby ensuring product quality. This production design also endows BWFRP pipes with a triple-layer structure: both the inner and outer layers are of crossed weaving, while the middle layer is of circumferential and longitudinal weaving. The inner and outer weaving layers, designed with different weaving angles, combined with the circumferential and longitudinal composite middle layer, form an ideal composite material product. This new type of piping avoids the disadvantages of traditional products, offering light weight, high strength, corrosion resistance, good thermal conductivity, and electrical insulation. Additionally, it boasts high hoop stiffness, resistance to high and low temperatures, and longevity.

II. Product Features:

1. Withstanding extreme temperatures: The pipeline boasts frost-resistant and high-temperature properties, capable of adapting to harsh environments. It remains undamaged and unshaped in extreme temperature conditions ranging from -50°C to 200°C.

2. High Impact Resistance: Due to the integrity and compactness of the fiber mesh, combined with the longitudinal and circumferential combinations, the product exhibits high strength in all directions. Thus, it has excellent resistance to external impacts, unlike traditional piping materials that have weaknesses in certain directions and are prone to damage under impact forces. The hardness is 5-6 times that of traditional spiral-wound cable pipes.

3. High electrical insulation: Made with superior alkali-free fiber and high-performance resin under high-voltage conditions, the product has high density, bubble-free texture, and excellent electrical insulation.

4. Smooth Interior: The pipe's interior surface is smooth, offering flexibility and resistance to external heavy pressure and damage caused by foundation settlement.
