Aluminum Conductors, Aluminum-Clad Steel ReinforcedCONSTRUCTIONAluminum Conductors, Aluminum-Clad Steel Reinforced (ACSR/AW) is a concentric-lay-strandedconductor consisting of aluminum-clad steel central core (Alumoweld) with one or more layersof hard drawn stranded aluminum wires. Alumoweld is a highly resistant steel rod, covered witha thick coating of pure aluminum, which is cold-drawn in order to obtain wires of the requireddiameters.The design and dimensions of ACSR/AW conductors are identical to those of ordinary ACSRconductors, except the steel core in ACSR conductor, which is aluminum-clad steel core inACSR/AW.APPLICATIONAluminum Conductors, Aluminum-Clad Steel Reinforced (ACSR/AW) can be used inMedium, High and Extra-High voltage transmission lines; also used for earth wires. In comparisonwith ACSR conductors, ACSR/AW conductors have considerable technical and economicaladvantages in overhead lines. Its lower weight combined with its higher current carryingcapacity and corrosion protection provide a longer life cycle, reduction in energy losses andsignificant cost saving during the operation of the line.APPLICABLE STANDARDAluminum Conductors, Aluminum-Clad Steel Reinforced (ACSR/AW) is designed and testedto meet:ASTM B 549However,requirements.can also supply a range of alternative designs to meet customer-specifiedTECHNICAL DATAComposition ( AL / AW )6 / 16 / 726 / 730 / 730 / 1954 / 754 / 19Final Modulus of ElasticityMPa74 50071 60071 60074 50072 50065 70063 700Coeff. of Linear ExpansionPer ºC x 10 -619.320.019.118.018.219.519.66/1 Wires18/1 Wires26/7 Wires30/7 Wires54/7 WiresThe above data is approximate and subject to manufacturing tolerance.25We reserve the right to change the above figures as a result of product development and/or changes in standard.
