Description
● GYTY53 Stranded Loose Tube Metallic Strength Member Armored Outdoor Cable:
The fibers, 200/ 250μm, are positioned in loose tubes 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.
● 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;
►Good crush tolerance,applies for duct and directly buried distribution;
►To assure the water-proof function by:
·Single steel wire as central strength member
·Special tube filling compound ensure a critical protection of fiber
·PSP enhances the ability to avoid moisture
·Fully filled in the cable
·Good water-blocking tape prevent the sinking vertically
►Complies with Standard YD/T 901-2009 as well as IEC 60794-1.
● Application:
►Aerial/conduit;
►Connecting communication equipment;
►Suitable for long-distance communication and indoor communication.
