Audited Supplier Brief Description:
This conductor is made from aluminium-magnesium-silicon alloy of high electrical conductivity containing enough magnesium silicide to give it better mechanical properties
after treatment. These conductors are generally made out of aluminium alloy 6201.
AAAC CONDUCTOR has a better corrosion resistance and better strength to weight ratio and improved electrical
conductivity than ACSR CONDUCTOR on equal diameter basis.
Applications:
AAAC aluminum alloy conductors are extensively used for overhead distribution and transmission lines adjacent to
ocean coastlines where there can be a problem of corrosion in the steel of an ACSR construction.
The aluminum alloy conductors are used in place of single-layer ACSR conductors (i.e., #6 to #4/0 AWG) to reduce power losses in overhead distribution and transmission
lines. The inductive effect of the ACSR's steel core is eliminated, hence increasing the operating efficiency of the line.
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 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 aluminum.
Features and Benefits:
Aluminum alloy conductors have a number of advantages over the use of the ACSR or all aluminum conductors.
Lower power losses than for equivalent single aluminum-
layer ACSR conductors. (The inductive effect of the steel core in the ACSR is eliminated).
• Simpler fittings than those required for ACSR.
• Excellent corrosion resistance in environments conducive to galvanic corrosion in ACSR.
• Strength and sag approximately the same as for equivalent 6/1 and 26/7 ACSR conductors.
• Outside diameters are the same as for standard ACSR conductors, permitting interchangeability of fittings.
• Greater resistance to abrasion than that for 1350 wires in all-aluminum or ACSR conductors.
Key Benefits:
· High tensile strength as compared to AAC conductor.
· Higher conductivity as compared to ACSR conductor.
· Better corrosion resistance than ACSR conductor.
