Optical data cable GYFZA04+33

armoredflame-retardantfire-resistant

Optical fibres are housed in loose tubes that are made of high-modulus plastic and filled with tube filling compound. The tubes (and fillers) are stranded around a non-metallic central strength member to form a cable core. The core is covered by a fire resistance layer. A LSZH inner sheath is extruded and armored with laminated aluminum tape. Then a PE second sheath and a nylon third sheath is extruded and wrapped with steel wires. Finally, a LSZH outer sheath is extruded. • Accurate process control ensuring good mechanical and temperature performances • The material of loose tubes, with good hydrolysis resistance and relatively high strength • Fire-resistant layer and LSZH sheaths ensuring good fire resistance and flame-retardant performances • Nylon sheath with high hardness providing certain anti-termite performance • Excellent crush resistance • Comply with IEC60331(no cooling), IEC60754-1&2, IEC61034 and IEC60332-3-24 • Standard length: 2,000m; other lengths are also available.
