Functional characteristics of HDPE bellows:

FRP cable protection pipe, with glass fiber as reinforcement material, is bonded with unsaturated resin. It has strong pressure resistance, light weight, smooth inner wall and small friction coefficient. It is easy to wear the cable without damaging the cable.

1. With high strength, it can be directly buried under the carriageway without adding concrete protective layer, which can speed up the construction progress of cable engineering.

2. The pipe is flexible and can resist the damage caused by external heavy pressure and foundation settlement.

3. Insulation, no electric corrosion, suitable for single core cable laying; It has the advantages of corrosion resistance and can be used in high-temperature saline alkali areas.

4. Flame retardant, good heat resistance, can be used at 130 ℃ for a long time without deformation.

5. The inner wall shall be smooth without scratching the cable. Rubber seal is added at the joint to adapt to thermal expansion and cold contraction, and prevent sand and mud from entering.

6. The design adopts socket connection mode to facilitate installation and connection.

7. The body has light weight, simple and convenient installation and construction. One person can move and two people can install locally, which can greatly shorten the construction cycle and reduce the installation cost. At the same time, the problems of long exposure time of road excavation and affecting urban traffic order shall be avoided.

8. Wide range of application: the composite FRP cable protection pipe is suitable for the protection pipe when the cable is buried. It is also used in high demand occasions such as cable crossing bridges and rivers. The supporting professional pipe pillow combination can form a multi-layer and multi row multi conduit pipe arrangement.
