Non-metallic Strength Member Cable(GYHTY)

 


·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 901-2001as well as IEC 60794-1.
