GYXY Non-Armored

Unitube Non-armored Cable(GYXY)

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 steel wires are placed at 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 critical protection of fiber

· Two parallel steel wires ensure tensile strength

· PE sheath protects the cable from ultraviolet radiation

· Small diameter, lightweight and friendly installation

· Long delivery length



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