BWFRP fiber woven extruded cable protection tube

The material of the fiber woven extruded cable protection tube is alkali free fiber yarn, composed of resin, glass fiber, and fillers. It adopts advanced weaving extrusion technology, and the entire product is manufactured with four layers of weaving: outer, inner, middle, and interlayer. Its characteristics are that the inner, middle, and outer layers are extruded and woven to form a high strength, good toughness, and the best longitudinal and transverse tensile strength of the fiber woven extruded cable protection tube. Product specifications:

1. 1colourGenerally, it is the primary color (milk white), and other colors can be agreed upon by both parties.

2. 2exteriorThe surface of the conduit should be free of defects such as cracks, layering, pinholes, burrs, impurities, poor adhesive areas, bubbles, etc; The internal and external surfaces should be smooth and flat, without any unevenness; The two ends of the conduit should be flush, without burrs or burrs, and the inner edges of the socket and socket should be chamfered to prevent damage when the cable is pulled into or out of the conduit.

3. 3lengthThe length of each protective tube is generally 6m, which can also be agreed upon by both parties. The maximum deviation of each tube length is± 20mm.

Performance characteristics of fiber extruded woven protective tube:

1. High ring stiffness: Due to the use of pultrusion weaving technology, the pipe has densely arranged glass fibers in both the longitudinal and circumferential directions, greatly improving the ring stiffness of this type of pipe. 2. Compared with traditional pipes, fiber woven extruded cable ducts have significantly improved strength and superior stress resistance. 3. Excellent electrical insulation. Due to complete changes in process conditions, long glass fibers are integrated and continuously formed under high temperature and pressure conditions, resulting in a significant increase in product density, no bubbles in the pipeline, and better insulation performance. 4. Corrosion-resistant fiberglass products themselves have the best corrosion resistance and can resist the erosion of the vast majority of chemical solvents. 5. Stable and unified quality is different from traditional fiberglass steel pipe single forming. The fiber woven pultrusion forming process is an integrated continuous winding pultrusion formed pipe, which intelligently controls production and cutting length, ensuring stable and unified product quality. 6. Excellent heat resistance stability is different from traditional fiberglass steel pipe single molding. The fiber woven extrusion molding process uses high temperature and high pressure during the production process, which greatly improves the heat resistance compared to the traditional process of curing at room temperature. 7. Good water resistance, different from traditional fiberglass steel pipe single molding, the fiber woven extrusion molding process has different usage conditions for fiber woven protective pipes during the production process
