（GYXY）Unitube Non-armored Cable

Description

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.

·Characteristics

· High strength loose tube that is hydrolysis resistant

· Special tube filling compound ensure a critical protection of fiber

· Two parallel steel wires ensure tensile strength

· PE sheath protects cable from ultraviolet radiation

· Small diameter, light weight and friendly installation

· Long delivery length

·Standards

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