Stranded Loose Tube Cable with Aluminum and Steel Tape plus Non-metallic Central Strength Member GYFTA53


Application: Duct/Aerial/Direct buried

In the GYFTA53 cable, single-mode/multimode fibres are positioned in the loose tubes, which are made of high modulus plastic materials, while the loose tubes should strand together around non-metallic central strength member (FRP) 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 longitndinally applied around the cable core ,then covered with a PE inner sheath; and the PSP is longitudinally applied around the PE inner sheath,before a PE outer sheath is extruded over it.


1. Excellent mechanical and temperature performance guaranteed by the accurate excess fibre ength
2. Critical protection to fibres, based on the excellent hydrolysis resistance and strength performance of tube material and special filling compound filled in the tube
3. Excellent crush resistance and flexibility
4. The following measures are taken to ensure the water blocking performance of the cable:
– Single FRP as the central strength member
– APL moisture barrier
– Special water-blocking filling compound in the loose tube
– 100% cable core filling
– PSP moisture barrier
– Water-blocking material
