The maximum vertical rise is set by the cable’s own weight and how much tension it can safely withstand. As you raise a cable in a vertical run, gravity creates tension that increases with length. The cable’s weight per unit length determines how much tension that length adds, and the cable’s maximum tensile rating defines the limit of how much tension the insulation and conductor can tolerate without damage. When the weight per length and the allowable tension reach that limit, you’ve hit the maximum rise.

Ambient temperature can slightly influence tension because materials expand or contract, but it does not define the safe height by itself. Jacket color has no bearing on strength or tension, and while a longer run means more weight, the actual constraint is how weight and tensile rating interact to cap the rise.
