Where can I get wire rated for high voltages?

Question

I'm looking for wire that can handle up to 10kv (10,000 volts) where can I find some???

Answer 1

Any electric supply place will have it, or can order it.  Look 'em up in the phone book under "electric".

Answer 2

A thin wire can also handle 10.000 volts, it is the amps that rates the cable.

A sparkplug cable (thin core) handles 50.000 or more but the amps that flow is low.

A car battery cable is thick to handle 100 amps or more when the starter motor is engaged at only 12 volts
