Aluminum Conductor Steel Reinforced (ACSR) CSA C49

Applications

ACSR conductors have been widely used in power transmission lines with various voltage levels,because they have such good characteristics as simple structure,convenient installation and maintenance,low cost large transmission capacity.And bare overhead conductors are also suitable for laying across rivers valleys and the places where special geographical features exist.

Construction

ACSR conductors are formed by several wires of aluminium and galvanized steel, stranded in concentric layers. The aluminum wire stranded or wires which form the core, are made of galvanized steel and the external layer or layers, are of aluminium. Galvanized steel core consist normally of 1, 7 or 19 wires. The diameters of steel and aluminium wires can be the same, or different. 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.
