I'm late to the party Steve, but this page was really helpful - thanks! I've been hunting out sources of irradiated PVC and at present the only one I can find that does it in solid-core, in the gauges and voltage ratings I need - 18, 20 and 22AWG in 300V and 600V - is Flex Wires in CA. They make those in a range of colours, also a range of temperature ratings including 105degC. I've asked about distributors as I doubt their minimum put-up is small enough for the likes of me: no longer than 100' and I'd prefer 25' in some cases. I'll post here if I get a reply from them.

Hi John, Thank you for your comments! Interesting point about Kynar. I didn't know that it's cross-linked. Also only thought of it as 30-AWG. However, I see it here : WesBell Electronics ...in sizes up to 20AWG and in lots of colors. 22AWG goes for $22.50@100ft. [Click on the part numbers to order even though they don't look like links.] Only thing is, the UL versions of the wire don't have voltage ratings, though the MIL versions are rated at 300V. Kynar dielectric strength is around 1kV/mil and the wire uses 5-mils. Of course, voltage rating is more complicated than dielectric strength.

Also Cross Linked PVDF (xl-pvdf) aka Kynar. found on mil spec wire such as type 44 and type 55. great stuff but, yeah you pay a price for it.

Hi Steve! Thanks (I think). Moi, a nerd? I don't know what you're talking about! [He says, taking the calculator case off his belt :]
