ACSR (Aluminium Conductor Steel Reinforced) / ACSR-AW

It’s the type of conductor most used worldwide and it is composed of a steel core and one or more hard drawn aluminium layers.

Introduction

It’s the type of conductor most used worldwide and it is composed of a steel core and one or more hard drawn aluminium layers.

The steel core, that is the mechanical support, can be composed of galvanized steel wires or Aluminium Clad Steel wires (ACS).

The wires of the conductive layers could be made of hard drawn aluminium or of thermal aluminium alloy and they have a rounded section.

Engineering

Even if the ACSR/ACSR-AW conductors are listed in the international norms, as EN 50182, De Angeli Prodotti can realize every customized composition.

Specifically for the conductive layers in aluminium or aluminium alloy, De Angeli Prodotti proposes alternative shapes as trapezoidal wires, “Z” wires, etc.

Advantages

The use of trapezoidal or “Z” wires allows a substantial raise of the filling-factor. Consequently, considering the same external diameter, the conductive section and the capability of energy transport increase remarkably. In addition, thanks to extremely flat surface, the drag coefficient (CX) decreases.

The use of ACS (Aluminium Clad Steel) wires as the core guarantees an ultimate resistance to the corrosion, especially in saline environments.

In the case of zinc coated wires, the use of grease provides an adequate protection.
