Description

GJFZY53- Fire resistant cable: The fibres, 250um, 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 flame-retardant sheath. After a corrugated steel tape armor is applied, the cable is completed with a outer flame-retardant sheath. 

  

Characteristics

Good 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 

  

Applications

Indoor distribution

Interconnect from outdoor to indoor for optical cable distribution equipment

  

Standards

Comply with Standard YD/T 1258.4-2005, ICEA-596, GR-409, IEC 60794, IEC 60331-25-1999 etc.
