Default High temperature wire connections

We have a lot of heated plates at work that production uses to fuse plastic pipe together. Some of them were built with boxes way too close to the heated surface so they burn up any normal connection we might use. Right now we have high temp wire that is soldered together and covered in a kind of fiberglass sheath. Obviously that isn't UL listed or even electrically insulating. I would like to replace this stuff and I'm wondering what you guys recommend.

The interior of these boxes can get up to 450 degrees Fahrenheit. Some don't get so high. All our machines automatically cut out at 490 degrees. I'd like to find a good connector and some kind of electrically insulating tape or whatever else that would be good for that.

What voltage rating do you need, 300 or 600?

Tempco makes 300v wire nuts and 600v terminal blocks that can handle your temp requirements.
