High voltage ceramic insulators have discs, which help handle higher voltages and greater mechanical stresses

🦁🦁🦁🦁🦁🦁🦁🦁180 -----> You forgot all about DC power. Here at our monastery we used to generate DC power and sold it to our neighbors here in town. Eventually MDU came to town and our customers switched to their AC power. After some time we did so too, but continued to generate AC power into the fifties, when we closed down our high pressure boilers, which only meant that we lowered the pressure to 15 psi and no longer kept a night shift on duty.
Yes, Yes, all well and good, but today they also use DC high voltage transmission. It is generated as DC Transmitted at high voltage across the countryside saving 1/3rd in cable and tower costs. At the distal end electronics is used to convert the DC back to AC with transformers to then lower the voltage.
DC was of course the first power delivered ion NYC by Thomas Edison. AC proved to be better, but in major cities, the power company still has "Edison" in its name, such as in "Consolidated Edison" And yes, they still deliver DC power to customers who require it. You can tell by looking at the meter, it is very different from what you are used to seeing.

Insulators are designed in discs to break electric fields
