Good wire. AWG seems to be accurate. The wire is very flexible and can therefore be laid very easily. I use this in the engine bay so I think 200C should be fine but I'll keep an eye on it to see how it holds up.
Pros
They are equipped with high-quality silicone rubber insulation. High temperature resistance 200 degrees C, low temperature resistance, in extreme cold -60 degrees C. Rated voltage: 600 volts. Outside diameter 4.5 mm, tolerance +/- 0.1 mm.
