The fibers,125μm,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 the filling compound to protect it from water ingress, the cable is completed with a thin polyethylene(PE) inner sheath.A layer of water-blocking tape is applied around the cable core to prevent water ingress all the same.After a corrugated steel tape armor is applied,the cable is completed with a PE outer sheath.
♦ Excellent mechanical and temperature performance
♦ Special tube filling compound ensure a critical protection of fiber and resist the water.
♦ Non-metallic central strength member FRP withstand axial loads.
♦ Inner sheath effectively lower the external mechanical loading.
♦ Corrugated steel tape longitudinal cover cable core and provide good crush resistance.
♦ PE sheath protects cable from ultraviolet radiation.
♦ 100% core filling water prevent cable jelly to ensure the cable watertight.
