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.

Product Description

GYHTZSH58-FR The cable 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 member 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 and then a layer of low-smoke, halogen-free flame-retardant inner sheath is extruded,then 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 cable 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 member 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. An fire-resistant layer is provided outside the cable core and then a layer of low-smoke, halogen-free, flame-retardant polyolefin (LSZH) sheath is extruded to form the cable.
GYMXTPH-FR optical cable is to insert 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-FRoptical cable selects high-performance refractory materials to provide thermal insulation protection for the optical fibers, and under high temperatures, an effective fireproof layer can be formed.
Select 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 properties.
The structure of double sheath and double armor 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 tubehas 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.
The sheath can adopt high-performance and low-friction sheath materials and a semi-dry structure design to meet the application requirements of different scenarios.
