which is why NONE EXIST, even for short distances.

Where do they hide all of the electrical poles in Manhattan, and every other downtown city area?

“Where do they hide all of the electrical poles in Manhattan, and every other downtown city area? “

Those are medium voltage lines. The substations are outside of the cities, for obvious reasons.

“Electric power can also be transmitted by underground power cables instead of overhead power lines. Underground cables take up less right-of-way than overhead lines, have lower visibility, and are less affected by bad weather. However, costs of insulated cable and excavation are much higher than overhead construction. Faults in buried transmission lines take longer to locate and repair. Underground lines are strictly limited by their thermal capacity, which permits less overload or re-rating than overhead lines. Long underground cables have significant capacitance, which may reduce their ability to provide useful power to loads.”
