Features

•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 Fiber Reinforced Plastics (FRP) are placed at the two side. The cable is completed with a polyethylene(PE) sheath.

•Characteristics

• Good mechanical and temperature performance

• High strength loose tube that is hydrolysis resistant

• Special tube filling compound ensure a critical protection of fiber

• Two parallel FRPs ensure tensile strength

• PE sheath protects cable from ultraviolet radiation

• Small diameter, light weight and friendly installation

• Long delivery length

•Standards

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