The problem is not Temperature.
your wire insulator for any Bifilar that will oeperate at HV, will have to handle the max voltage. so Stan talked about 20KV, each wire insulation will have to handle at least 12KV.
I got a quote for the perfect wire for this but a little to much for my wallet;

Subject : RE: Need price on some wire for R&D
Hi,
I'm doing some R&D and need some magnet wire to make
an high voltage transformer 20KV. the HV winding is
to be bifilar wound so the wire would need to resists
the HV field that will build between the 2 windings.
I was looking at your website and it looks like your
24-27B51S migh be the right product for this
transformer.
let me know your opinion, a price list and where can
I get the wire.
Thank You
Here is the responce:
I think the part number you referenced would work. PN
24-38B44S has an even higher voltage withstand due to
additional insulation thickness.
PN 24-27B51S (~686 ft/lb) $29.26 /lb. 20 lb. min.
PN 24-38B44S (~670 ft/lb) $42.96 /lb. 20 lb. min.
This wire is sold directly from the factory. How much
wire are you looking for?
I wrote back asking if they would cell only 4 lb, and they never responded.
