  "abstract": "In this article, we study the updated constraints upon the radio transient signals arisen from superconducting cosmic strings (SCSs) in light of the recent observational developments of fast radio bursts (FRBs) astronomy. By assuming that the currents in these strings follow the Poisson distribution, we show that two parameters can be severely limited by FRB experiments, which are the characteristic tension and current of cosmic strings, respectively. In particular, we investigate data sets from two FRB experiments namely: Parkes and ASKAP. Our analyses show that, Parkes jointly with ASKAP can constrain the parameter space for superconducting cosmic strings well enough. Our numerical calculation estimates that the possibly allowed parameter space for strings are give by $G\\mu \\sim [10^{-16}, 10^{-13}]$ and $I_c\\sim [10^{0}, 10^{2}]$GeV.",
