Non metallic strength member loose tube stranded cable (GYFTY) Wasin Fujikura
Description
The fibers, are positioned in a loose tube made of a high modulus plastic. The interstice inside and outside of the tubes are filled with a water-resistant filling compound. A fiber reinforced plastic rod(FRP), coated with polyethylene if necessary locates in the center of core as a strength member. Tubers (and fillers) are stranded around the strength member to form a compact and circular cable core. A layor polyethylene sheath is extruded around the cable core to form a cable.
Feature
Full section water blocking construction, provide good performance of moisture-proof and water resistance;
Special filling gel filled loose tubes provide perfect optical fiber protection.
Dielectric FRP rod with high modulus as central strength member.
The flexible buffer tubes are easily to route in closures.
Excellent mechanical and temperature performance.
Jacket provide superior protection against UV radiation, fungus, ,abrasion and other environmental factors.
All dielectric structure, light weight, easy installation, good electromagnetic resistance and suitable for operating in electrical system or frequently lighting areas.
Strict craft and raw material control enable lifespan over 30 years.
Performance
Application: long haul and building network communication;
Installation: duct/aerial;
Operating temperature: -40～+70℃;
Bending radius: static 10*D/ Dynamic20*D.
