FRP strength member
- Specification: many kinds, dia 0.4-5.2mm
- Features:
1) not sensitive to the lightning strike, applied to the areas which are common with frequent lightning and rain;
2) Not obstructed by induced current and can be installed close to the power unit and device;
3) No harmful gas that would affect the optical transmission indicators;
4) Has the characteristics of high tensile and light weight;
5) bullet-proof, ant-proof and anti-tooth proof.
