Description

AAC, AAAC, ACSR are also known as Overhead Conductors, Transmission Conductors and Power Distribution Conductors. AAC is also known as aluminium stranded conductor. These cables can also be recognised by their full names of All Aluminium Conductor (AAC), All Aluminium Alloy Conductor (AAAC) an Aluminium Conductor Steel Reinforced (ACSR).

Service Performance

1. High tensile strength
2. Long life
3. Light in weigh
4. Suitable for high as well as extra high overhead

Features

• High strength to weight ratio
• Better sag characteristics
• Improved electrical properties
• Excellent resistance to corrosion

Construction

Standard 6201-T81 high strength aluminum conductors, conforming to ASTM Specification B-399, are concentric-lay- stranded, similar in construction and appearance to 1350 grade aluminum conductors. Standard 6201 alloy conductors are similar to other alloy conductors commercially known as Ardival, Aldrey or Almelec. They were developed to fill the need for an economical conductor for overhead applications requiring higher strength than that obtainable with 1350 grade aluminum conductors, but without a steel core. The DC resistance at 20°C of the 6201-T81 conductors and of the standard ACSRs of the same diameter are approximately the same. Conductors of the 6201-T81 alloys are harder and, therefore, have a greater resistance to abrasion than conductors of 1350-H19 grade aluminum.
 

Anti-corrosion

Anti-corrosion ACSR is used in the corrosive areas like coastal areas or industrial zones. This ACSR is filled with anti-corrosive grease applied on the gaps between stranded wires and their external surfaces.

Generally, anti-corrosion ACSR is divided into three types according to the method of greases coating :
*Light Anti-corrosion Type : Only steel wires are coated
*Medium Anti-corrosion Type : All the inner layers are coated
*Heavy Anti-corrosion Type : All the inner and outer layers are coated

Application

Aluminium Conductors are predominantly used in Overhead Line applications and for primary and secondary power distribution.
The higher strength ACSR conductors are used for river crossings, overhead earth wires, and installations involving extra long spans. The advantage of ACSR is that it has high tensile strength and is lightweight, which means over longer spans it needs less supports. ACSR is available with varying percentages of steel core to achieve different strengths. One of the advantages of this conductor in particular is that the desired strength can be achieved without a loss of ampacity.

AAC is used mainly in urban areas where the spacing is short and the supports are closer together. The advantage of AAC conductors is that they have a high degree of corrosion resistance; for this reason they are used extensively in coastal areas. AAC Conductors were developed as a consequence of the galvanic corrosion that ACSR conductors are susceptible to.

AAAC is used as bare overhead conductor for power transmission and distribution lines on aerial circuits that require larger mechanical resistance than AAC. AAAC also has better sag characteristics and a better strength to weight ratio than AAC. AAAC Cables have lower weight per unit length and slightly lower resistance per unit length than ACSR.
