A fuse blows when a certain *current* passes through it. P = V I cos

supply high power at low current if you use high voltage, which is how
a thin wire can be used to sneak in high power. Jed made the same
mistake as you, thinking that you need high current to get high power;
it's not necessarily the case. Incidentally, I've known all this kind
of stuff since age 9, when I began building radios.
Correct, but you are forgetting an important thing.
The generally used cables are rated and tested for maximum voltages and
cannot be used for much higher voltages (kV) due to safety reasons.
If you would want to do this you would need special cables which can be
used for high breakdown voltages!
Kind regards,
