[FRP cartoon sculpture] its friction coefficient is small

First, the layout, characteristics and functions of FRP cable protection tube:

①GRP cable protection tube has the advantages of high strength, light weight, non-deformation, and slippery surface. The friction coefficient is small, and the cable can be slid smoothly without damaging the cable. Effectively dealt with the low strength of PVC plastic pipe and heavy weight of galvanized steel pipe, which easily scratches the cable when wearing the cable. Moreover, the weight is only 1/4 of the steel pipe and 1/10 of the concrete pipe. Therefore, the transportation is convenient and the construction is simple.

Where is the official website of cpvc:

② Non-electrical corrosion, non-magnetic, suitable for single-core cable laying, no need to deal with extra punishment to prevent the occurrence of eddy currents, and to overcome the problem that eddy currents are easily generated by magnetic materials.

③ Good water resistance, can be applied in wet or water for a long time, and the popular composite materials are not water resistant, and can only be applied under the condition of drying. It avoids the signs of cable corrosion caused by direct buried laying, and CPVC power pipes also prevent galvanized steel pipes from rusting in wet soil for a long time, leading to the loss of the cable protection function.

④ Heat resistance and fire resistance are better than epoxy glass fiber reinforced plastic and plastic. It can be used for a long time at 130 ° C, and does not burn in case of fire.

⑤ It has the advantages of insulation, anti-corrosion, no rust, and long application life. As usual, it can be covered for more than 50 years.

Second, the advantages of FRP cable protection tube in power grid support:

(1) The construction is convenient and simple. Because glass fiber reinforced plastic cable is used to lay the protective tube, it is light in weight and simple in construction measures. The sealing ring is used for the connection between the tube and the tube. There is no need for welding like a steel tube. time.

(2) High strength and good water resistance. Because the terrain of the end of the cable is complicated, it must pass through the road and pass through the wet section, and at the same time cross the underground drainage channel. The strength of the protective tube, corrosion resistance and waterproof performance are all extremely strict.

(3) The construction and laying measures are simple and can be handled properly because of the excavation of the diameter of the glass cable tube during construction, the exposed time is long, and the convex problems such as affecting urban traffic. Its burial can be carried out in sections. Suddenly backfill and level the road. To deal with the main traffic, it can realize the excavation and burying at night, backfill the pavement, and can be opened to traffic as usual during the day, effectively dealing with the disadvantages of long time-breaking of direct buried and cable trench laying.

(4) Adopting the laying of FRP cable protection tube can bury and lay cables in advance without interrupting the electricity, without affecting the power supply. At the end, you only need to cut power for a short time and connect the cable power supply and the down-conductor, which improves the reliability of power supply.

(5) The price of FRP cable protection pipe is not much different from that of galvanized steel pipe, but because it has the incomparable advantages of galvanized steel pipe, the large amount of FRP cable protection pipe has been put into use. Broad prospects.

The characteristic strength of FRP cable protection tube is high, and it is used for direct burial under the carriageway. There is no need to add a mixed soil shielding layer, which can speed up the progress of construction of glass cable protection tube. The toughness is good, and it can withstand the damage caused by the external pressure and the settlement of the foundation. Electrical insulation, flame retardant, good heat resistance, can be used at 130 degrees high temperature and long time without deformation. Resistant to corrosion and long service life, can withstand the corrosion of various aggressive media such as acid, alkali, salt and organic solvents, and its service life can reach 50 years.
