How do I read a cable temperature rating?
It belongs to the jacket and insulation compound, not to the cable family — the datasheet must state a range and the material.
Answer: the rating is a property of the jacket and insulation compound, so a datasheet that gives a temperature without naming the material is incomplete.
Material drives it — PVC, TPE and silicone behave differently at both ends of the range.
Both ends matter — a low-temperature limit is what fails first in cold-weather outdoor use.
Continuous vs peak — a peak rating is not a continuous rating.
For outdoor or industrial use, state the operating range in the requirement and ask for the compound by name.
