The Loss of Tensile Strength of Hard-Drawn Conductors by Annealing in Servicec

摘要: Although the literature contains many results of tests on loss tensile strength wires held at various temperatures for time durations, data are very disperse, and it is difficult to apply them determine a particular conductor as result long-term annealing in service. This paper examines effect reduction cross-sectional area during drawing, operating temperature, duration annealing. The heat capacity conductors following short-circuit or lightning impulse current shown. need more work effects tension stranding stressed.
