ACSR 120/20mm2 (26/2.38, 7/1.85mm) IEC 61089/EN50182
ACSR conductors are formed by several wires of aluminium and galvanized steel, stranded in concentric layers. By varying the relative proportions of aluminium and steel, the required characteristics for any particular application can be reached. A higher U. T. S. Can be obtained, by increasing steel content, and a higher current carrying capacity by increasing aluminium content.
ACSR conductors are recognized for their record of economy, dependability and favourable strength / weight ratio. ACSR conductors combine the light weight and good conductivity of aluminium with the high tensile strength and ruggedness of steel. In line design, this can provide higher tensions, less sag, and longer span lengths than obtainable with most other types of overhead conductors.
