In this article we update constraints on superconducting cosmic strings (SCSs) in the light of the recent observational developments of fast radio bursts (FRBs) astronomy. Assuming strings follow an exponential distribution characterized by a current, we show that two parameters in our context, which are the characteristic tension ($$G\mu $$ ) and a parameter which describes the aforementioned exponential distribution ($$I_c$$ ), can be constrained by FRB experiments. Particularly, we investigate data sets from Parkes and ASKAP. We looked at a parameter space where $$G\mu \sim [10^{-17}, 10^{-12}]$$ and $$I_c\sim [10^{-1}, 10^{2}]$$ GeV, and found our results show that Parkes jointly with ASKAP can constrain the parameter space for SCSs.
