Flame Retardant and Fire Resistance cable

Flame-retardant and fire-resistance optical cables can control the spread of fire during a fire and maintain the integrity of the communication line. It can meet the requirements of flame retardant and fire-resistant standards such as CPR, UL, and IEC60332.

Product Description
  • GYHTZSH58-FR – the cables are made by inserting single-mode optical fibers into loose tubes made of high-modulus polyester material (PBT), with waterproof compounds filled inside the tubes. Non-metallic strength members are used at the center of the optical cable.The loose tubes (and possible filling ropes) are twisted around the central strength member to form a compact circular cable core. The corrugated steel tape is longitudinally wrapped. Afterwards a layer of low-smoke, halogen-free flame-retardant inner sheath is extruded.  Also a mica tape fire-resistant layer is provided on the inner sheath surface. Finally, the steel tape is longitudinally wrapped and then a low-smoke, halogen-free flame-retardant outer sheath is extruded into a cable.
  • GYFHTH-FR The cables are made by inserting single-mode optical fibers into loose tubes made of high-modulus polyester material (PBT) with waterproof compounds filled inside the tubes. Non-metallic strength members are used at the center of the optical cable. The loose tubes (and possible filling ropes) are twisted around the central strength member to form a compact circular cable core. Fire-resistant layer is provided outside the cable core and afterwards layer of low-smoke, halogen-free, flame-retardant polyolefin (LSZH) sheath is extruded to form the cable.
  • GYMXTPH-FR optical cable is constructed by inserting single-mode or multi-mode optical fibers into a metal loose tube made of 304 stainless steel, with waterproof compounds filled inside the tubes. Low-smoke, halogen-free, and flame-retardant polyolefin (LSZH) sheath is extruded to form the cable. Two parallel steel wires are placed on both sides of outer sheath.
Product Advantages
  • Reasonable control of the excess length of the optical fiber, resisting the optical fiber breakage caused by the thermal expansion and contraction of the optical cable during the test process.
  • GYFHTH-FR Optical cable consists of high-performance refractory materials to provide thermal insulation protection for the optical fibers, and using high temperatures, an effective fireproof layer can be formed.
  • Selected fire-resistant and high-temperature-resistant materials – mica tape, to provide excellent fireproof and heat insulation effects.
  • The outer sheath is made of high flame-retardant material, and the optical cable has excellent flame-retardant features.
  • The structure of double sheath and double armour ensures the excellent mechanical and environmental performance of the optical cable.
  • It meets the highest requirements of the BS 6387 standard for the CWZ class fire resistance, ensuring the integrity of the communication lines.
  • The 304 stainless steel tube has excellent resistance to damage by animals.
  • It can effectively alleviate the tension of pipeline resources caused by the expansion of communication pipe networks within cities.
  • It can be constructed and laid in sections, with fast air-blowing speed, long laying distance and high construction efficiency.
