Performance
GYTA33 is an outdoor communication optical cable of metallic strength member of the loose tube jelly-filled structure, with Al-polyethylene laminated sheath and single-layer thin round steel wire armored polyethylene outer sheath.
The loose tubes are made of high modulus plastics (PBT) and filled withwater resistant filling gel. Loose tubes are stranded around the metallic central strength member, cable core is filled with cable filling compound. The corrugated aluminum tape is longitudinally applied over the cable core, and combined with polyethylene (PE) inner sheath. Galvanized steel wires are stranded around inner sheath, and then extruded with PE outer sheath.
Feature
1, High quality optical fiber provides good transmission performance
2, Accurate fiber excess length control ensures excellent mechanical and temperature performance
3, Special filling gel filled loose tubes provide perfect optical fiber protection
4,All section water blocking ensure the cable core reliable performance of moisture-proof and water block
5, Corrosion resistance phosphated steel wire with high Young's modulus as central strength member givesdesirable tensile strength
6, Longitudinally Armor with both side coated aluminum tape and stranded steel wires armoring meet therequirements of high crush resistance, tensile strength, bulletproof property, heavy duty direct buryunderwater installation
7, Strict craft and raw material control enable lifespan over 30 years
