Loose tubes(or some fillers)stranded around the central strength member to form the cable core, the cable core longitudinally bound by aluminum polyethylene laminate, further bonded by the inner sheath, moisture barrier and then corrugated steel tape laminated with polyethylene on both sides, finally sheathed with medium density polyethylene under vacuum condition Characteristics: □ Good mechanical, tension-resistant, crush resistant, temperature and transmission performance □ High young抯 modulus phosphatized steel wire as central strength member, PE buffer extruded to outside of steel wire when necessary. □ The loose tube, cable core and all interstices filled with moisture-proof gel and compound , prevent water ingress longitudinally □ The aluminum tape laminated on both sides with polyethylene and closely bonded to PE inner sheath possesses the function of radial moisture-proof for the cable □ Armoured with longitudinal corrugated steel tape laminated with polyethylene □ Longitudinal water blocking tape at the inner side of the steel tape tightly bonded to the MDPE sheath ensures radial moisture-proof and reinforces mechanical crush resistance as well as prevents water ingress longitudinally Product specifications: Item Properties and requirements Fiber count 2 ～ 144 Min. Bending Radius Install 25x diameter of cable Static 12.5x diameter of cable Temperature Range -40癈 ～ +60癈 Nominal Weight(kg/km) Depends on different specifications Laying method Direct buried
