Cable construction:Loose tubes (or some with fillers) stranded around the central strength member to form the cable core, the cable core longitudinally bound by aluminum ployethylene laminate, further bonded to the inner PE 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 performanceHigh Young's modulus phosphatized steel wire as central strength member, PE buffer extruded to outside of steel wire when necessaryThe loose tubes, cable core and all interstices filled with moisture-proof gel and compound, prevent water ingress longitudinallyThe aluminiunm 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 polyethyleneLongitudinal 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. |
