SRML wire

Shawn,

Have you looked at Omega Engineering? (the thermo.....everything people). Look for Hookup wire on their website.

Problem is that those only go up to like 20AWG and it's in bundles. I can't use smaller wires because I use those lines to run servo motors. Thanks for the suggestion though.

I am confused by your application. If the environment is hot (i.e. greater than 200°C) then you may want to use wire with ceramic beads as insulators. You see this in ovens. If, however, your heat is coming from a servo motor then what you need is a heat sink in the form of oversized conductors and perhaps some ceramic fiber insulating tape. Other considerations would include whether the wires are stationary or being moved around. Ceramic beads don't like being banged around. Ceramic fiber tape can solve tough problems and it is a lot more elegant than duct tape (i.e. engineering tape).

My application is power and control signals going to a liquid level sensor. The trick is, the liquid happens to be molten aluminum. The wire ways that the wires go through is insulated, but regular THHN would melt at one drop. These wires last several years, but I was wondering if there was something higher rated to make them last longer.

Shawn,

Have you looked at MI cable? It is tougher to install because you have to seal the ends against moisture penetration, and these seals can be temperature sensitive. However, high temperature versions of the cable itself can be rated for much higher than the NEC tables' 250ºC. Other wire types also rated for 250ºC include the fluorocarbon types: PAF, PFAH, PTF, and TFE.
