I'd love someone smarter than me to do a back-of-the-napkin job on that. Are we talking a firecracker, a cherry bomb, a few kilos of TNT, or a MOBA?

  1 meter of 1mm diameter wire with 1 million amperes amounts to 750kJ, or ~180g of TNT. A superconductor blowing up across the length and distributing the energy doesn't seem as bad a whole transmission line's energy released at a point fault.

    that also sounds like pretty ok risks for an under sea cable. though given one break you have to replace the entire cable might cancel it out.

      You could break it into sections connected by liquid nitrogen superconductors, or maybe extremely heavy gauge copper ones.
