Here is the reply from Rhode Island Wire:

Hi Nathan

The folks that make the wire probably know the material to use and thickness needed to get it rated where they want it.  I doubt they test every batch, but I'm sure they check to make sure often enough and it's likely rated over 50 and they feel safe calling it "Rated for 50 Volt".

We buy the plastic wire, and put cloth on it.  Not sure of their safety procedures or even their manufacturing process, but they must be trustworthy or they'd be out of business.

Now, you are not the first person looking for this stuff.

Here is what some folks do.

You purchase at least 300 feet of the required wire rated proper for your Radio Application.

We can cover it with cloth and saturate it to keep the cloth on and make it fire resistant.

There must be at least 300 feet to string the machine up.

I've added a 'your mileage may vary' warning to the top of my post.

I wonder if this is something that a company like Radio Daze would want to supply?

Another alternative would be to set up a kickstarter and gauge (heh) interest in people who'd commit to buying some amount of it.
