Aluminium alloy (AAAC) contains a small percentage (about 0.6%) of silicon and magnesium elements. It
(i) Strength : About twice that of aluminium 1350 (EC).
(ii) Weight : 20% (approx.) lighter than ACSR conductor of equal diameter.
(iii) Corrosion resistance : It has a high resistance to atmospheric corrosion which is suitable for coastal and indusrial areas.
liable to damage during installation which is an important advantage of EHV transmission lines where corona and radio interference is a major consideration.
(v) Termination : Much simpler jointing accessories required compared to ACSR.
(vi) AC Resistance : AAAC is an non-magnetic material. It does not exhibit the magnetic core losses found in ACSR conductor

Note: 1) *Not a standard Size in BS 215 : Part 2.
ACSR is a composite, concentrically stranded conductor in which the light weight and good conductivity
of aluminium are combined with the high tensile strength of steel. It is composed of one or more layers
of EC grad hard-drawn aluminium wires helically stranded around an inner core of high strength zinc-
coated steel wires. The inner steel core may be a single zinc coated steel wire, or concentrically stranded
of one or more layer of zinc-coated steel wires.
ACSR has long been widely used as overhead high tension transmission lines and has an established
reputation for economy and dependability. The illustrarion below shows typical standard sizes and
stranding patterns.10
