Resulting from a five-year development programme involving Nexans’ technology
centres in France and Belgium, this innovative overhead line technology consists
in a thermal resistant aluminium conductor wrapped around a composite carbon
core. Compared with a traditional ACSR (Aluminium Conductor Steel Reinforced)
which uses steel core, the composite carbon core of the same diameter is much
lighter and 50 percent stronger. Most importantly, the carbon core’s coefficient
of thermal expansion is roughly one tenth of that of steel, so it expands (and
‘sags’) much less when heated by the high current flowing in the conductor,
enabling the vital safety clearances to be maintained between the conductor and
the ground, even at high operating temperatures.
