Hi
My military sources tell me that they can get anything they can
imagine...but not necessarily at a price you'd want to pay.
Plain ol' silicone spark plug wire is fine for HV to a few amps, and you
really should NOT be subjecting HV lines to an environment in which armor
coating is desired. If this were the case, I'd suggest a raceway or an
insulated conduit -- teflon lined, perhaps.
Assuming reasonable shielding and bypassing, a short run of HV DC should
not cause or be subject to interference.
You wouldn't need a coaxial spark plug -- they're ALL made that way -- but
it might ne handy to use the elescrode and porcelain insulator sawed off of
one to provide a secure mate to a factory crimped spark plug wire.
