Description:
Stranded Loose Tube Armored Flame-retardant Cable（GYTZA53）
Details:
Stranded Loose Tube Armored
Flame-retardant Cable（GYTZA53）
Description
The fibers, 250µm, are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. A steel wire, sometimes sheathed with polyethylene (PE) for cable with high fiber count, locates in the center of core as a metallic strength member. The tubes (and fillers) are stranded around the strength member into a compact and circular core. An aluminum Polyethylene Laminate (APL) is applied around the cable core. Then the cable core is covered with a thin flame retardant inner sheath, which is filled with jelly to protect it from water ingress. After a corrugated steel tape armor is applied, the cable is completed with a flame retardant outer sheath.
Characteristics
Good mechanical, temperature performance and flame- retardant property
High strength loose tube that is hydrolysis resistant
Special tube filling compound ensure a critical protection of fiber
Crush resistance and flexibility
The following measures are taken to ensure the cable watertight:
Steel wire used as the central strength member
Loose tube filling compound
100% cable core filling
APL moisture barrier
PSP enhancing moisture-proof
Water-blocking material
Standards
GYTZA53 cable complies with Standard YD/T 901-2001 as well as IEC 60794-1.
Application: Duct / Aerial/Direct buried
