Stranded Loose Tube Flame-retardant Cable（GYTZS）

 


13-2 （GYTZS）.jpg


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 PE for cable with high fiber count, locates in the center of core as a metallic strength member. Tubes (and fillers) are stranded around the strength member into a compact and circular cable core. The PSP is longitudinally applied over the cable core, which is filled with the filling compound to protect it from water ingress. The cable is completed with a flame-retardant sheath.

  

Characteristics

Good mechanical and temperature performance

High strength loose tube that is hydrolysis resistant

Special tube filling compound ensure a critical protection of fiber

Specially designed compact structure is good at preventing loose tubes from shrinking

Crush resistance and flexibility

Special sheath material ensures excellent flame-retardant performance

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

PSP enhancing moisture-proof

 

Standards

GYTZS cable complies with Standard YD/T 901-2001 as well as MT386-1995; and passes MA certification.

Application: Duct /Aerial /Direct buried
