GYFXY Non-Metallic

Unitube Non-metallic Non-armored Cable(GYFXY)

The fibers, 250μm, are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. Over the tube. water-blocking material is applied to keep the cable watertight. Two parallel Fiber Reinforced Plastics (FRP) are placed on the two sides. The cable is completed with a polyethylene(PE) sheath.




· Good mechanical and temperature performance

· High strength loose tube that is hydrolysis resistant

· Special tube filling compound ensures a critical protection of fiber

· Two parallel FRPs ensure tensile strength

· PE sheath protects the cable from ultraviolet radiation

· Small diameter, lightweight, and friendly installation

· Long delivery length



GYFXY cable complies with Standard YD/T 769-2003.
