I was thinking of something: They state "not to use in conditions
over 0 Celsius"? This may mean the cables rely on the surrounding
environment to cool them (the insulation can't handle higher
temperatures, like operation at room temperatures which would
raise the temperature of the insulation above a certain level).
Because they are intended to be used only in colder temperatures
to melt ice, it may assume a low level of heat before the
insulation breaks down.
I've never worked with them, though.
