Product Description:
GJFZY53-Fire resistant cable: The fibres,250I m,are positioned in a loose tube made of a high modulus plastic.The tubes are filled with a water-resistant filling compound. A Fibre Reinforced Plastic (FRP) locates in the center of core as a non-metallic strength member. The tubes (and fillers) are stranded around the strength member into a compact and circular core. Then the cable core is covered with an inner flameretardant sheath.After a corrugated steel tape armor is applied, the cable is completed with a outer flame-retardant sheath.
Features:
CharacteristicsGood mechanical, temperature performance and fire resistant property
High strength loose tube that is hydrolysis resistant
Special tube filling compound ensure a critical protection of fiber
Good crush resistance and flexibility
The following measures are taken to ensure the cable watertight:
Single fiber reinforced plastic as the central strength member
Loose tube filling compound
100% cable core filling
PSP enhancing moisture-proof
Water-blocking material
Scientific design with strict processing
