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.

 · Good mechanical and temperature performance

        · High strength looes 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

GYFTA53 cable complies with Standard YD/T 901-2001as well as IEC 60794-1.
