Stranded Loose Tube Non-metallic Strength Member Cable（GYHTY）

Details:

Stranded Loose Tube Non-metallic

Strength Member Cable（GYHTY）

13-2 GYHTY 副本.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 Fiber 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. After the cable core is filled with filling compound, it is covered with thin PE (polyethylene) inner sheath. Then, a layer of aramid yarn is applied as additional strength member and the cable is completed with a polyethylene (PE) outer sheath.

  

Characteristics

Good mechanical and temperature performance

Aramid yarn strength member ensures good performance of tensile strength

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:

Single Fiber Reinforced Plastic as the central strength member

Loose tube filling compound

100% cable core filling

  

Standards

GYHTY cable complies with Standard YD/T 901-2001 as well as IEC 60794-1.

Application: Aerial
