9. A Human Hand and a 400,000-volt cable comparison
Found in: Global (Subterranean) Est. Installation costs: $500,000 per mile.
You may picture a smallish wire when you think of a cable, such as the one that powers your laptop, electricity, and other devices. Although that is accurate for lower voltages, stronger materials are required for cables with greater voltages.

This is an underground cable with a voltage of 400,000 volts. This cable is the same size as a hand; we can only imagine the tremendous shock one would receive when coming into contact with such an object. Since the highest voltage for these cables is 400K, they are used for large-scale projects like installations for the National Grid and other projects.
