High‐capacity buried power lines

Abstract

With the growth of metropolitan areas and their demand for electric power, it is becoming increasingly difficult to transport adequate electric power to such centers by conventional transmission lines. Several recent studies have concluded that by the end of the next decade it will be hard to make do without installing high‐capacity underground cables to transport power to the central cities. Overhead lines are in many ways unacceptable in built‐up areas, and conventional underground cables have insufficient carrying capacity.
