Aluminium
Conductor Steel Reinforced can be manufactured to different
strengths by requirement. The conductor is constructed from a
solid steel core, surrounded by aluminium stranding. The solid
steel core is strong yet ductile, while the outer stranding of
aluminium gives excellent conductivity with a low weight and
low cost. The ACSR conductor is available in a range of steel
strengths from as little as 6% up to 40%. The stronger the
steel percentage, the more arduous tasks it can take on; the
highest strength conductors are used as overhead wires, for
river crossings, and any installations which require a
particularly long span without support.
ACSR also has the double benefit that as well as being high
strength, it is also lightweight. ACSR conductors have a higher
diameter than AAC and AAAC due to their steel core, and due to
this they can obtain a higher corona limit, giving the
advantage for high voltage overhead lines. ACSR is also used
for local distribution, suspended from wooden poles or other
alternative methods.
Selection of conductor size, type and strength should take into
account factors such as electrical load, voltage regulation,
and corona losses. Environmental conditions such as ice and
wind loading, extreme temperatures and vibration should also be
considered.
