dependant on your earthing system,ie trunking and conduit where you can earth across joints you can,t beat physics.
want less resistance ,increase conductors
yes you can cool your conductors use wacky materials ,but copper and aliminium is what you got
you can try to alter your max permissable zs by calculation or use a b type mcb
