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. A Fiber Reinforced Plastic (FRP) locates in the center of core as a non-metallic strength member. The tubes (and fillers) are stranded around the strength member into a compact and circular core. An aluminum Polyethylene Laminate (APL) is applied around the cable core. Then the cable core is covered with a thin polyethylene (PE) inner sheath, which is filled with jelly to protect it from water ingress. After a corrugated steel tape armor is applied, the cable is completed with a PE outer 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

Crush resistance and flexibility

The following measures are taken to ensure the cable watertight:

Single Fiber Reinforced Plastic as the central strength member

Loose tube filling compound

100% cable core filling

APL moisture barrier

PSP enhancing moisture-proof

Water-blocking material

 

Standards

GYFTA53 cable complies with Standard YD/T 901-2001 as well as

Application: Duct / Aerial/Direct buried
