The 6 fibers are positioned in a loose tube made of PBT. The tube is filled with a water-resistant filling compound and amroured with a layer of PSP longitudinally.Between the PSP and the loose tube water-blocking material is applied to keep the cable compact and watertight.Two parallel steel wires are placed at the two sides of the steel tape.The cable is completed with a PE sheath.
Inside tube,Lashed,Direct buried
1.Excellent mechanical and tempertureperformance
2.Special tube filling compound ensure a critical protection of fiber and resist the water
3.Better anti-water performance by the swell tape
4.Corrugated steel ensure the water blocking and lateral crush resistance performance
5.Two parallel steel wires ensure tensile strength
6.Outer sheath protects cable from ultraviolet radiation
