            Composite power cable duct


            Product introduction
            Plastic glass fiber reinforced plastic composite pipe is the third generation of new type of cable expansion sleeve. It is a new product developed by our company in order to overcome the various defects in the use of sand glass fiber reinforced plastic cable conduit in the modern market. This product uses PVC, PE, MPP to make the inner surface layer. It has fatal defects such as preventing the cable from loosening from the inner surface and seizing the cable. The outer layer is a glass fiber reinforced plastic layer. The fiberglass is impregnated with flame retardant resin for winding. In addition to the excellent performance of FRP cable ducts, it is also an ideal high-quality pipe product that replaces galvanized steel pipes and vinylon cement pipes. Because of its service life and stiffness are more than twice that of plastic-coated steel pipes, it has the advantages of low cost and never rust. Is the best alternative to plastic coated steel pipe. Has been widely used in urban power grid reconstruction, municipal road construction, electrified railway reconstruction, highway construction and other cables, optical cables, fast cables laying protection.

            Features

            I. Material properties

            The plastic glass fiber reinforced plastic composite pipe is made of PVC, PE and MPP with an inner surface layer, an outer layer is a glass fiber reinforced plastic layer, and glass fiber is impregnated with a flame retardant resin for winding, which makes up for the defects of the performance of the sand fiberglass cable conduit. Because the service life and rigidity are more than twice that of plastic-coated steel pipes, it has the advantages of low cost and never rust, and is widely used in urban power grid reconstruction, municipal road construction, electrified railway reconstruction, highway construction and other cables, optical cables, Cable laying protection.

            The color of the outer layer of the catheter should be the color of the material itself or according to customer requirements, and the color should be uniform; the outer layer of the catheter should be pure glass fiber reinforced plastic, and the outer surface should be free of cracks, delamination, burrs, impurities, and poor rubber areas; and the color of the inner layer of the catheter Generally orange red, the inner surface should be smooth without unevenness; the two ends of the catheter should be flush, without burrs, burrs; the inner and outer layers should be bonded together, and there should be no delamination between the two layers.

            Second, heat resistance

            The plastic glass fiber reinforced plastic composite pipe can be used for a long time under the environment of -40-130 ° C, which does not deform and has sufficient strength.

            Third, the insulation performance

            Plastic glass fiber reinforced plastic composite pipes can withstand high voltages of more than 30,000 volts. In the current urban power grid transformation, high-voltage power cables are generally less than 30,000 volts. Therefore, for urban power grids, the electrical insulation performance of this protection pipe is greater than that of power cables. Insulation performance, it will be safer to use.

            Fourth, compression performance

            After the material modification of plastic glass fiber reinforced plastic composite pipe, the service life and rigidity are more than twice that of plastic-coated steel pipe, which is significantly higher than the requirements of the relevant national departments for the rigidity index of buried plastic pipe rings. For ground plastic pipes, the ring stiffness should be above 8 Kpa. It can be seen that the buried pipe has excellent buried pressure resistance and is completely suitable for various road constructions.

            Five, flame retardant performance

            The use of PVC, PE and MPP as the lining improves the heat resistance and can be extinguished immediately after the fire, so the flame retardancy and smoke density index are significantly improved.

            Installation performance

            The plastic glass fiber reinforced plastic composite pipe is light in weight, high in strength, and simple in construction and laying methods. It can be buried at night, backfill the road, and open to traffic as usual during the day. It adopts elastic sealing rubber ring socket connection, convenient and fast installation and connection, double O rubber Ring sealing, good connection sealing performance, can prevent groundwater leakage, and effectively protect the safety of power cables.

            Eight, corrosion resistance

            Corrosion resistance, aging resistance, long service life up to more than 50 years.
