ACSR Aluminum Conductor Steel Reinforced Single Core Hard Conductor Overhead Multicore

ACSR aluminum conductor steel reinforced Single Core Hard Conductor Overhead Multicore

APPLICATION

ACSR conductors are widely used for electrical power transmission over long distances, since they are ideal for long overhead lines spans. They are also used as a messenger for supporting overhead electrical cables.

Strands
When selecting stranded wire, it is important to specify the number of strands which make up the conductor. Wires with a high amount of strands are more flexible than those with a lesser amount. Conductor wire typically has at least 7 strands: one in the middle with 6 surrounding strands. More flexible wires commonly have 19, 37, or 49 strands. Very large wires, or those manufactured for very flexible applications, may have 70 or more strands.

ACSR bare conductor meets or exceeds the following ASTM specifications

B230 Aluminum 1350-H19 Wire for Electrical Purposes
B232 Concentric-Lay-Stranded Aluminum Conductors, Coated-Steel Reinforced (ACSR).
B498 Zinc-Coated (Galvanized) Steel Core Wire for Use in Overhead Electrical Conductors.
B500 Metallic Coated Stranded Steel Core for Use in Overhead Electrical Conductors.

CONSTRUCTION

ACSR conductors are formed by several wires of aluminium and galvanized steel, stranded in concentric layers. The wire 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.
