GFRP Cable strengthen core introduction

GFRP Cable strengthen core introduction

1.Technical characteristics of GFRP Optical cable Strengthen core

1.Non-metallic material is not sensitive to electric shock, apply to thunder and rainy climate areas;

2.GFRP strengthen core can be used and installed close to the power lines and the power supply device, not interfered by power lines or power supply device produced induced current;

3.Compared with metal core, GFRP won’t influence optical fiber transmission index because of gas from chemical reaction between metal and factice.

4.Compared with metal core,GFRP has the characteristics of high tensilestrength, light weight;

5.GFRP optic cable strengthen core can bullet proof, prevent tooth bite and anti-termite.
