Description
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. 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.
Product Features
·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
·APL layer
Product Standard
·GYTA cable complies with Standard YD/T 901-2009 as well as IEC 60794-1.
