Stranded Loose Tube Cable with Aluminum Tape and Steel Wire Armor GYTA33


Application: Duct/Direct buried

In the GYTA33 cable, single-mode/multimode fibres are positioned in the loose tubes, which are made of high modulus plastic materials, while the loose tubes strand together around metallic central strength member into a compact and circular cable core. For certain high fibre count cables, the strength member would be covered with polyethylene (PE). The water-blocking materials are distributed into interstices of the cable core. An APL is longitudinally applied around the cable core,then covered with a PE inner sheath; and the single layer of steel wires is applied over the PE inner sheath before a PE outer sheath is extruded over it.

1. Excellent mechanical and temperature performance
2. Better tensile strength performance with steel wires
3. Critical protection to fibres, based on the excellent hydrolysis resistance and strength performance of tube material and special filling compound filled in the tube
4. Excellent crush resistance
5. The following measures are taken to ensure the water blocking performance of the cable:
– Single steel wire used as the central strength member
– Special water-blocking filling compound in the loose tube
– 100% cable core filling
– APL moisture barrier
