Direct Buried Cellular Cable

These Filled Cables are used in Telecommunication Network of Saudi Arabia. This is intended for use in Secondary Network between Cross Connection Cabinet and Distribution Points and Primary Network between the Exchange and Cross-Connection Cabinets. Filled Cables having Single Polyethylene Sheath with Moisture Barrier are used in DUCT Installation. While Filled Cables having Double Sheath (Inner & Outer) are used for Direct Burial Cable.

General Specification : Saudi Telecom Specification TS -2002 & IEC 60708
Conductor : Solid annealed plain copper wire as per ASTM B 3.
Insulation : Each Conductor shall be covered with continuous layer of Cellular Foam-Skin High Density Polyethylene. Insulation Shall be identified as Table-1 & Table-2.
Assembly : Two Insulated conductors twisted together to form a pair. 10 Pairs are assembled to form a sub-unit. Up to 100 pairs, these sub-units are assembled to form the cable.
Moisture Barrier : Aluminum Tape, coated on both sides with co-polymer as per ASTM B 736, is applied longitudinally with a suitable overlap to prevent the ingress of water to the cable.
Inner Sheath : Extruded black Linear Low Density Polyethylene, as per ASTM D 1248, continuously bonded to the aluminum tape to prevent of water penetration to the core and the transport of water between the sheath and the tape.
Outer Sheath : The Inner sheath with Viscous Flooding Compound shall by covered by Black High Density Polyethylene by Extrusion Process.
