What is the difference between AAC AAAC and ACSR?

AAAC Conductor AAC Conductor and ACSR Conductor are a part of Overhead Conductors, Transmission Conductors and Power Distributor Conductors. These cables are All Aluminum Conductor (AAC), All Aluminum Alloy Conductor (AAAC) and Aluminum Conductor Steel Reinforced (ACSR). These aluminum conductors are made up of one or more strands of aluminum wire which depends on the specific application.


AAC (All Aluminum Conductors)

This conductor is formed by one or more layer of pure aluminum AA1350-H19, hard drawn. The conductivity is 61%. This kind of AAC Conductor (All Aluminum Conductor) has a very low value of specific mechanical resistance and it is used for short lengths and not for long spans.

It has a very good resistance to corrosion and his modulus of elasticity is characterized by a law that considers the formation of the conductor (number of wires and layers).

These AAC are refined, Aluminum stranded conductor with a minimum metal purity of 99.7%. It is mainly used in urban areas so as to provide the perfect support to the cables as it takes less space and its installation is easy. AAC Conductor (All Aluminum Conductor), are used extensively in Railway and Metro industries.

AAC Conductor Standard

  • BS 215 PART 1
  • BS EN 50182
  • IEC 61089
  • ASTM B 231/B 231M
  • DIN 48201 PART 5

AAAC (All Aluminum Alloy Conductors)

The material which is used on these conductors is an aluminum alloy AA-6101. Its special alloy with Magnesium and Silicium with an excellent conductivity value. The average value is 53%. These AAAC Conductor (All Aluminum Alloy Conductors) are used as a bare conductor cable on aerial circuits which requires a larger mechanical resistance than AAC.

The biggest difference between AAAC Conductor and AAC Conductor are the materials from which they are constructed from. AAC Conductor is manufactured from electrolytic ally refined aluminum with a 99.7% minimum purity.

AAAC Conductor is made from an Aluminum alloy. The mechanical resistance of AAAC (All Aluminum Alloy Conductors) is higher than AAC conductor and it also maintains a high corrosion resistance.

ACSR(Aluminium Conductor Steel Reinforced)

Aluminium Conductors Steel Reinforced (ACSR Conductor), also known as Bare aluminium conductors, are one of the most widely used conductors for transmission. The conductor consists of one or more layers of aluminium wires stranded over a high strength steel core that can be single or multiple strands depending on the requirement. There can be various stranding combinations of Al and steel wires lending flexibility to obtain suitable current carrying capacity and mechanical strength for the application.

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