FRP cable protection pipe is a new type of composite material pipe. It is mainly made of glass fiber as reinforced material and was bonded with unsaturated polyester resin. FRP cable protection pipe is needed when cables is buried.
It is an alternative to steel pipes and concrete pipes. It is widely used in power cables and telecommunication cables construction projects to protect cables from external force and crash.
The advantage include high strength, high pressure resistance, and light weight. Easy to install, safe and reliable, strong insulation performance, can resist the corrosion of various corrosive items, strong anti-water leakage ability, and has more than 50years long service life.
It has Because the glass fiber reinforced plastic cable protection pipe has various advantages in the industry, The performance has surpassed the performance of plastic pipes in the same industry, so it is gradually favored by engineering personnel in the industry.
Feature of FRP Cable Protection Pipe
●High strength
Used for direct burial under the traffic lane, without adding a protective layer of concrete, which can speed up the construction progress of the project.
●Good toughness
Able to resist damage caused by external pressure and foundation settlement.
●Good electrical insulation
Flame-retardant and heat-resistant properties, and can be used for a long time at a high temperature of 130 degrees without deformation.
●Corrosion resistance
Long service life, corrosion resistance of various corrosive media such as acid, alkali, salt and organic solvent, and its service life can reach 50 years.
●Smooth inner wall
The inner wall is smooth and does not scratch the cable. The rubber sealing ring socket joint is convenient for installation and connection, and adapts to thermal expansion and contraction.
●Small proportion and light weight
One person can lift it and two people can install it, which can greatly shorten the construction period and reduce the installation cost. At the same time, it can avoid problems such as long exposure time of road excavation and affecting urban traffic order.
● No electrical corrosion, non-magnetic
Unlike magnetic materials such as steel pipes, the eddy current will cause the cable to heat up and be damaged.
●Widely application
FRP cable protection tube is suitable for protection tube when cables are buried in the ground, and also used for high-demand occasions such as cable crossing bridges and river crossings. Using the matching professional tube-pillow combination, it can form a multi-layer multi-row multi-pipe arrangement.

Construction & Installation
- Direct buried under the driveway, no need to add concrete protection layer to speed up the construction progress.
- Mainly adopt “O” type sealing ring connection method, and the special position can be connected by flange or bonding.
3. It can be placed several layers with specific accessory to satisfy different laying requirements.
It can be used as protective pipe during burying projects. It can be used in the river and bridge cable laying constructions.
