High temperature conductors consist of central tension cables such as extra-high-strength steel, aluminum-clad steel and aluminum-clad invar. Such conductors consist of a heat resistant aluminum conductor layer with a maximum continuous temperature of 150°C~230°C enabling the transmission of 1.5~2 times larger current compared to ACSR. Thus, installation time and costs can be dramatically reduced by replacing the ACSR with high temperature conductors that increase current capacity instead of expanding new cables. Doing so provides various solutions for urban and salinated areas and long-span transmission sections. STACIR, XTACIR, GSTACSR, ACSS, Composite Core(LSCC) cables are also known as high-temperature low-sag conductors(HTLSC) and enable high temperature and low sag for cables with limited sag without reinforcing steel towers.
