tor del ACSS es ligeramente inferior a la del ACSR para la misma carga de hielo/viento.
✔✔ El costo del ACSS cardinal por
libra es, generalmente, de 10 a
20 % mayor que el del ACSR
cardinal.

En el diseño de nuevas líneas de transmisión aérea, se deben considerar los
conductores de fase para altas temperaturas, ya que pueden producir un aumento del 50 % en la capacidad térmica de la línea con un costo adicional del
proyecto inferior al 10 %. Las pérdidas
eléctricas en la línea que utiliza ya sea
ACSR o ACSS son difíciles de predecir
a lo largo de la vida de la línea, pero
ambos conductores producirían las
mismas pérdidas de energía. Los conectores de compresión para los ACSS
son esencialmente los mismos que los
de los ACSR y pueden ser usados con
cualquier tipo de conductor.
La principal ventaja de utilizar un
conductor de HT es que se evitan posibles limitaciones futuras en el flujo
de potencia cuando se relacionan con
la capacidad térmica de la línea. Este
aporte de robustez está disponible por
una inversión adicional muy modesta.

EHV and UHV transmission lines"

de transmisión a tensiones muy altas
y ultra altas), IEEE Trans. Power App.

existing overhead lines" (Conductores

del CIGRE, París, 2019.
"Guide to overall line design" (Guía
para el diseño general de líneas), Folleto técnico 638 del CIGRE, París, 2015.

Si el costo total del proyecto de la nueva línea (materiales y mano de obra) se
desglosa en un 30 % para los conductores y un 50 % para las estructuras (véase el folleto técnico 638 del CIGRE),
entonces el aumento del costo por el
uso de ACSS es aproximadamente de 2
a 3 % para el material conductor y de 5
a 10 % para las estructuras. El aumento
del costo total del proyecto es inferior
al 10 %, y el aumento de la capacidad
térmica de la línea es del 50 %. El costo
de las pérdidas eléctricas se mantiene
esencialmente sin cambios, un 3 % menos para el ACSS que para el ACSR.
