Composite fiberglass reinforced plastic frp cable protection pipes are made of high-strength glass fiber as reinforcing material and according to certain formula. It is formed by winding, rolling, curing and compounding, which has the unique superiority of composite material, and is equipped with pillow support, which plays the role of fixed heat dissipation.
The FRP cable protection pipes produced by our company can be divided into mechanical winding type and mortar winding type.
Features of FRP cable protection pipes
With high strength and strong resistance to external load, it can be buried directly in the ground and used for direct burial under the traffic lane without concrete protection layer, which can speed up the construction progress of the cable project.
Designed with plug-in connection method to adapt to thermal expansion and cold contraction. It is light in weight and can be carried by one person and installed by two people on the spot, which can greatly shorten the construction period and reduce the cost of installation works.
Strong corrosion resistance, can resist the erosion of various acids, high salt and alkali, sewage and other corrosive soils and fluids.
No eddy current loss and electric corrosion, good insulation, conducive to cable laying and operation.
Good flame retardant and heat resistant performance, no deformation in high temperature for long term use. The inner wall is smooth and burr-free and will not scratch the cable.
FRP cable protection pipe is flexible and equipped with flexible joints to resist the pressure from external heavy pressure and uneven settlement of the foundation.
Using FRP cable protection pipe can avoid the long exposure time of road excavation, affecting the urban traffic order and other phenomena.
Long service life, up to 40 years in underground use. The overall performance and cost performance is better than other materials of cable protection pipe.
