Just to be sure, I have consulted my professional electrical engineer colleagues. We agree that there is some space for ambiguity. When one (overground) power line (which is composed of several conductors) goes underground, the power line continues as one or several underground cables, depending on the technical implementation. High-power lines are always implemented underground as several cables with every cable carrying one conductor, as seems to be shown in the example picture https://lh3.ggpht.com/-CnkQkGiPmbs/UFM6M2N0lUI/AAAAAAAAArk/IMZxA3i6SmY/s1600/tunnel.png
My conclusion: I would simply suggest to accept both power=line and power=cable as equivalent. The average mapper is not an electrical engineer after all.
