The protective sleeve of filament wound GRP cable is made of glass fiber and unsaturated resin. It is composed of inner braided layer, middle layer and outer braided layer. By pultrusion process, four or seven layers can be selected according to different pressure levels. By adjusting the winding procedure, the winding angle can be adjusted and the production of pipes with different pressure levels can be realized

Functional characteristics of filament wound FRP pipes:

1. Glass fiber reinforced plastic cable protection tube has the product characteristics of antimagnetism and insulation, which can prevent the single core cable from being damaged due to the formation of closed magnetic circuit;

2. The inner wall of FRP pipe produced by filament winding technology is smooth and flat, with small friction coefficient and good wear resistance. During laying, the damage to cable can be greatly reduced and the working efficiency can be improved;

3. The FRP pipe can withstand the impact force of 1kg heavy hammer at 2m height at 0 ℃, which fully reflects the low-temperature impact performance of the material is fully applicable to the construction environment.

4. Filament wound FRP pipes have good flame-retardant performance, and can be extinguished immediately after leaving the fire.

Use method of filament wound GRP:

Filament wound FRP pipes can be used in urban power grid construction and transformation projects, industrial park, community engineering construction and urban municipal reconstruction projects, etc. according to different engineering requirements, a multi-layer and multi column cable duct arrangement system should be formed. The specific use is as follows:

1. Urban power and communication cables are used as protection pipes when they are laid underground.

2. Protection pipe shall be used when the cable is directly buried in the carriageway or laid at the crossing.

3. When cables cross bridges, rivers and other special environments, they are used as protective pipes.

Filament wound FRP pipe is an organic combination of pultrusion technology and winding technology, which overcomes the shortcomings of low transverse strength of pultrusion profile, low production efficiency and high waste of winding pipe, and is another liberation of productivity of FRP industry.
