GYFZA04+33 Multi-armored Fire-resistance Optical Cable Anti-rodent & Anti-termite for Railway Transportation

■ Introduction:

Optical fibers are housed in loose tubes that are made of high-modulus plastic and filled with tube filling compounds.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. An LSZH inner sheath is extruded and armored with laminated aluminum tape. Then a PE second sheath and a nylon third sheath are extruded and wrapped with steel wires. Finally, an LSZH outer sheath is extruded.

■ Features:

• Accurate process control ensures good mechanical and temperature performances
  

• The material of loose tubes with good hydrolysis resistance and relatively high strength
  

• Fire-resistant layers and LSZH sheaths ensure good fire resistance and flame-retardant performances
  

• Excellent crush resistance
  

• Nylon sheath with high hardness provides certain anti-termite performances
  

• Comply with IEC60331(no cooling),IEC60754-1&2,IEC61034 and IEC60332-2-24
