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.
The cable core is filled with the filling compound to protect it from water ingress, over which a thin PE inner sheath is applied.
After the water blocking material is placed outside the inner sheath, the PSP is longitudinally applied.And then,the cable is completed with a PE outer sheath.
Feature
♦ 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.
♦ Inner sheath effectively lower the external mechanical loading.
♦ Corrugated steel tape longitudinal cover cable core and provide good crush resistance.
♦ PE sheath protects cable from ultraviolet radiation.
♦ 100% core filling water prevent cable jelly to ensure the cable watertight.
