High-Temperature Resistant Overhead Conductors

durably loadable up to 150°C. Increased capacity - enhancement of transmission performance. In times of limited availability of overhead line routes, upgrading existing overhead lines has gained increased importance. LUMPI-BERNDORF has specialized in this area and offers solutions with thermally resistant cables, utilizing an aluminum-zirconium alloy. Zircon raises the recrystallization temperature, thereby allowing an increase in the permissible operating temperature to 150°C. To meet the mechanical requirements of overhead line construction, thermally resistant overhead line cables are reinforced with Stalum or specially alloyed steel wires. Both standard cross-sections and customized special designs can be offered.
