Popis: To cope with future requirements, the transfer capacities of distribution systems as well as of transmission systems in Europe need to be increased. Therefore, repowering of existing overhead lines with high-temperature low-sag conductors (HTLS) can be one interesting possibility. Due to the limited experiences with that technology, current research of TU Dresden, the Federal Institute for Materials Research and Testing (BAM), and 50Hertz Transmission GmbH investigates the ageing behaviour of several different HTLS technologies in a consortium with other European partners. In this context, accelerated ageing tests of conductors and its corresponding fittings with combined mechanical and electrical loads are performed. To evaluate the changes due to ageing, several mechanical tests of the conductors are carried out and the contact behaviour of the fittings is analysed.
