Characteristics:
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.
Overview:
1.Good mechanical and temperature performance
2.High strength loose tube that is hydrolysis resistant
3.Special tube filling compound ensure a critical protection of fiber
4.Crush resistance and flexibility
5.The following measures are taken to ensure the cable watertight:
①Single Fiber Reinforced Plastic as the central strength member
②Loose tube filling compound
③100% cable core filling
④APL moisture barrier
⑤PSP enhancing moisture-proof
⑥Water-blocking material
