Study on sag characteristics calculation of CFCC Composite Core Wire

[摘要] With the rapid growth of the domestic economy, especially the development of urbanization, the demand for transmission capacity has also increased. The existing transmission lines can no longer meet the requirements, so the development of the capacity-enhanced wires is particularly important. Stranded carbon fiber composite core wire is a new type of capacitance-enhanced wire, as a second generation carbon fiber wire, it has excellent mechanical and electrical properties. In this paper, based on the existing research results, the temperature-sag performance is calculated and analyzed, and its superior sag characteristics in the operation of the hanging net are demonstrated.
