| Bare Aluminium (ALUMINIUM) Electrical Conductors |
 |
|
|
| AAAC All Aluminium Alloy Conductor |
|
| Applications |
 |
| Used as bare overhead conductor for primary and secondary distribution. Designed utilizing a highstrength Aluminium alloy to achieve a high strength-to-weight ratio; affords better sag characteristics. Aluminium alloy gives AAAC higher resistance to corrosion than ACSR. |
|
| Specifications |
|
AAAC bare conductor meets or exceeds the following ASTM specifications:
B-398 Aluminium Alloy 6201-T81 Wire for Electrical Purposes B-399 Concentric-Lay-Stranded 6201 J81 Aluminium Alloy Conductors |
|
| Construction |
|
Standard 6201-T81 high strength Aluminium conductors, conforming to ASTM Specification B-399, are concentric-lay-stranded, similar in construction and appearance to 1350 grade Aluminium 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 Aluminium conductors, but without a steel core.
The DC resistance at 20"C of the 6201-T81 conductors and of the standard ACSR of the same diameter are approximately the same. Conductors of the 6201 J81 alloys are harder and, therefore, have a greater resistance to abrasion than conductors of 1350-H 19 grade Aluminium. |

ACAR bare conductor meets or exceeds the following ASTM specifications:
B-230 Aluminium Wire, 1350-H19 for Electrical Purposes
B-398 Aluminium Alloy 6201-T81 for Electrical Purposes
B-524 Concentric-Lay-Stranded Aluminium Conductors, Aluminium Alloy Reinforced
ACAR, 1350/6201 |
|
| Construction |
|
| Aluminium alloy 1350-H19 wires, concentrically stranded about an Aluminium alloy 6201 core. Although the alloy strands generally comprise the core of the cable, in some constructions they are distributed in layers throughout the Aluminium alloy 1350?H19 strands. |

| AAC All Aluminium Conductor, Classes AA, A, B, C |
|
| Applications |
|
| Stranded 1350 Aluminium conductors shown in this section of data are classified, as follows: |
|
| Class AA |
|
For bare conductors usually used in overhead lines. |
|
| Class A |
|
For conductors to be covered with weather-resistant materials and for bare conductors where greater flexibility is required. |
|
| Class B |
|
For conductors to be insulated with various materials and for conductors indicated under Class A where greater flexibility is required. |
|
| Class C |
|
For conductors where greater flexibility is required |
|
| Compact strand conductor for use in bare overhead applications or for use with weather-resistant coverings or insulations is also available. |
|
| Note |
: |
Classes refer to stranding and are an indication of relative conductor flexibility, AA being the least flexible, C the most flexible |

| ACSR Aluminium Conductor, Steel Reinforced |
|
| Applications |
|
| Used as bare overhead transmission cable and as primary and secondary distribution cable. ACSR offers optimal strength for line design. Variable steel core stranding enables desired strength to be achieved without sacrificing ampacity. |
|
| Specifications |
|
bare ACSR conductors meet or exceed the following ASTM specifications:
B-230 Aluminium Wire, 1350-H19 for Electrical Purposes
B-232 Aluminium Conductors, Concentric-Lay-Stranded,Coated Steel Reinforced
(ACSR)
B-341 Aluminium Coated (Aluminized) Steel Core Wire for Aluminium Conductors,
Steel Reinforced (ACSR/AZ)
B-498 Zinc Coated Steel (Galvanized) Core Wire for Aluminium Conductors,
Steel Reinforced (ACSR)
B-500 Zinc Coated and Aluminium Coated Stranded Steel Core for Aluminium
Conductors, Steel Reinforced (ACSR) |
|
| Construction |
|
ACSR is a concentrically stranded conductor composed of one or more layers of hard-drawn 1350H19 Aluminium wire stranded with a high?strength coated steel core. The core maybe single wire or stranded depending on the size.
The proportions of Aluminium and steel can be varied to obtain the relation between current-carrying capacity and mechanical strength best suited to each application.
Core wire for ACSR is available with Class A, B or C galvanizing; "aluminized" Aluminium coated (AZ); or Aluminium clad (AW).
Additional corrosion protection is available through the application of grease to the core or infusion of the complete cable with grease. |
