APPLICATIONS:ACSR has the established reputation for economy and dependability in powertransmission lines. Also used for primary and secondary distribution lines. Widerange of steel content from 7% to 40% can be achieved by different stranding, tomeet desired strength. Electrical losses by corona effect are greatly reduced, due tothe larger diameter size of this design. Economical transmission and distribution ofelectrical energy can be achieved by ACSR, at very high voltages and distances.SPECIFICATIONS:ACSR Aluminum Conductors Steel Reinforced for High Voltage (HV) and MediumVoltage (MV) Transmission Overhead Lines are usually manufactured according toASTM B232, BS 3242, DIN 48204, TS IEC 1089CONSTRUCTION:ACSR is a composite concentric-lay-stranded conductor. Galvanized steel strand orstrands form the central core of the conductor, around which is stranded one ormore layers of EC Grade Aluminium wires. The steel core may consist of a singlestrand or a concentric stranded cable of 7, 19, 37, or more wires. Numerouscombinations of aluminum and steel strands and layers are possible.FEATURES AND BENEFITS:ACSR conductors are recognized for their record of economy, dependability andfavorable strength / weight ratio. ACSR conductors combine the light weight andgood conductivity of aluminum with the high tensile strength and ruggedness ofsteel. In line design, this can provide higher tensions, less sag, and longer spanlengths than obtainable with most other types of overhead conductors. The steelstrands are added as mechanical reinforcements. The cross sections aboveillustrate some common stranding. The steel core wires are protected fromcorrosion by galvanizing.
