Description

All Aluminum-Alloy Conductors (AAAC) is a concentric-lay-stranded conductor consisting of aluminum-alloy wires available in both single layer and multi-layer constructions.

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.
All Aluminum-Alloy Conductors (AAAC) can be used in Medium, High and Extra-High voltage transmission lines. AAAC offers better sag performance due to the high strength-to-weight ratio provided by the aluminum-alloy. In addition, AAAC provides a higher corrosion resistance than ACSR conductors.
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.
