The fibers,200/ 250μm, 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 PSP is longitudinally applied over the inner sheath, the cable is completed with a PE outer sheath.
·Good mechanical and temperature performance
·High strength loose tube that is hydrolysis resistant
·Special tube filling compound ensure a critical protection of fiber
·Specially designed compact structure is good at preventing loose tubes from shrinking
·PE sheath protects cable from ultraviolet radiation
·To assure the water-proof function by:
·Single steel wire as central strength member
·Special tube filling compound ensure a critical protection of fiber
·Fully filled in the cable
·PSP layer
•GYTS cable complies with Standard YD/T 901-2009 as well as IEC 60794-1.
