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