¡¡¡¡The fibers, 250m£¬are positioned in a loose tube made of a high modulus plastic. The tubes are lied with a water-resistant Ring compound.A steel wire locates in the center of core as a metallic strength member.Tubes (and Hers) are stranded around the strength member into a compact and circular cable core. An Aluminum Polyethylene Laminate (APL) is applied around the cable core£¬witch is lied with the Ring compound to protect it from water ingress.Then£¬the cable core is covered with a thin PE inner sheath.And a PSP is longitudinally applied over the inner sheath£¬the cable is covered with a PE outer sheath.After the single-steel armored£¬the cable is finally completed with an outer sheath.
¡¡¡¡Good mechanical and temperature performance
¡¡¡¡Single-steel ensure good performance of tensile strength
¡¡¡¡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:
¡¡¡¡1.Steel wire used as the central strength member
¡¡¡¡2.Loose tube filling compound
¡¡¡¡3.100% cable core fillip
¡¡¡¡4.APL moisture barrier
¡¡¡¡5.PSP enhancing moisture-proof
¡¡¡¡6.Water-blocking material
