How advanced conductors work
CTC Global ACCC: about twice the capacity of steel-core wire · 28% more aluminium · less sag
Re-string old towers with a wire built around a carbon-fibre core and the same line carries about twice the power. Play a heat-wave day on the old wire, where the line hits its limit, then the same day after reconductoring. Every number comes from one model.
Sources: CTC Global, ACCC conductor (about twice the capacity of ACSR; 28% more aluminium at no weight or diameter penalty; hybrid carbon and glass fibre core; lower sag and losses). The line voltage, ratings, resistance, temperatures, sag curves, clearance, weather and demand are illustrative; real ratings come from IEEE 738 and each line's survey.
