AAC,AAAC,ACSR,ACSR/AW,AACSR&ACAR conductor widely used in power transmission lines with various voltage levels. since they have such good characteristics as simple structure, convenient installation and maintenance, low cost for the line, large transmission capacity and are also suitable for laying across rivers and valleys where special geographical teatures exist. 

Specification of the Bared Overhead Conductors:

(1) all aluminium conductor (AAC)

(2) all aluminimum alloy conductor(AAAC)

(3) aluminum conductor steel reinforced (ACSR)

(4) anti-corrosion type ACSR

(5) aluminimum conductor aluminimum clad steel reinforced(ACSR/AW)

(6)rear earth aluminimum conductor steel reinforced(ACSR/RE)

(7)aluminimum conductor aluminimum alloy reinforced(ACAR)

AAC All Aluminium Conductors

All-aluminium conductors are the most favored type for use in the construction of relatively short span distribution schemes and are in common use on lines for voltage up to 60 KV. Another frequent application for all-aluminium conductor is in flexible busbar connections. Although aluminium-to-copper connections can be made, it is better to use aluminium conductors for service connections, as various forms of covered cable being available for this purpose. The data sheets show the most common sizes of conductors but other sizes, to any Recognized standards or customer specification can also be supplied. AAC insulated with XLPE or PVC can be supplied as per the customers' requirement. 

ACSR Aluminium Conductor Steel Reinforced

The mixed construction of ACSR makes it a very flexible medium from a design point of view. By varying the relative proportions of aluminium and steel the ideal conductor for any particular application can be produced. Generally, ACSR consists of a galvanized steel core of 1 wire, 7 wires or 19 wires surrounded by concentric layers of aluminium wire. When a conductor with a high current carrying capacity and comparatively low strength is required, special constructions are available with a high aluminium content. 

AAAC All Aluminium Alloy Conductors

This section deals with heat-treatable magnesium silicon type aluminium alloys to BS EN 50182, the electrical and mechanical properties of which all fall within the values suggested by Publication 104 of the international Electro technical Commission. Conductors to all other recognized specifications can also be supplied. The alloys referred to have higher strength but lower conductivity than pure aluminium. Being lighter, alloy conductors can sometimes be used to advantage in place of the more conventional ACSR.

Applications
Used as bare overhead conductor for primary and secondary distribution. Designed utilizing a high-strength aluminum alloy to achieve a high strength-to-weight ratio; affords better sag characteristics. Aluminum alloy gives AAAC higher resistance to corrosion than ACSR.

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.

Specifications
AAAC bare conductor meets or exceeds the following ASTM specifications :

B-398 Aluminum Alloy 6201-T81 Wire for Electrical Purposes
B-399 Concentric-Lay-Stranded 6201-T81 Aluminum Alloy Conductors.
