 If you can't find any HV wire anywhere (like me) why dont you simple use
 coaxiel wiring, use the centre wire, feed that through some hose pipe, and
 fill the hose pipe with oil. That will supress the corona, and possibly make
 it safe to handle the cables even when energised.
 
 Just a little idea

Hi Neil, all,

The high voltage cable that is used to carry the high voltage from the 
HV transformer to the x-ray tube head is perfactly designed for this
purpose. It consist of three seperate conductors wrapped inside a
~ 3/8" thicked walled rubber insulation. This insulation is in turn 
wrapped with a conductive carbon tape and the carbon tape is then
wrapped with aluminum screen mesh. Then the aluminum mesh is
then wrapped in a thin (1/16" thick) white (beige) rubber sheath. This,
in turn, makes for a nice flexible ~1"  cable. Of  course the carbon tape
and aluminum mesh are to be grounded and this is like a large coax
cable that can handle at least 75 kV, because that's what it's designed
for. Steve Flowers sells a lot of x-ray surplus euipment on ebay and he
can be contacted at : <<sflow26426-at-aol-dot-com>> 


BTW, I tested the x-ray cable on my coil with it disconnected from
the coil and energized: there's NO corona hiss, even at 17 kV :-)
