ACSR Conductor

Aluminium Conductors Steel Reinforced

These 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 7, 19, 37 and 61 wires. The diameters of steel and aluminium wires c an be the same, or different.

APPLICATIONS
  • Overhead transmission and distribution lines medium, high and extra high voltage.
