The fibers, 125μm,are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. A steel wire, sometimes sheathed with polyethylene (PE) for cable with high fiber count, locates in the center of core as a metallic strength member. Tubes (and fillers) are stranded around the strength member into a compact and circular cable core. An Aluminum Polyethylene Laminate (APL) is applied around the cable core, which is filled with the filling compound to protect it from water ingress. Then, the cable is completed with a PE sheath.
♦ Excellent mechanical and temperature performance
♦ Special tube filling compound ensure a critical protection of fiber and resist the water.
♦ Single steel wire as the central strength member to withstand axial loads.
♦ PE sheath protects cable from ultraviolet radiation.
♦ 100% core filling water prevent cable jelly to ensure the cable watertight.
♦ AL tape longitudinal cover cable core as moisture barrier.
