Overhead transmission lines are so 1950s.

Invest in your country.

Japan is earthquake country so they get a pass.

India however...

Japan is slowly burying all their overhead lines into the sidewalks. A lot of urban streets look so much nicer now than they did 10 years ago.

It’s probably no worse in an earthquake than the water mains, which would inherently be a lot more rigid than cables with intentional slack built into every segment.

Investing on your country would be connecting more people to electricity not make the sky look better

[-] vzq@lemmy.world 4 points 10 months ago

The sky looking better is just one thing. No more blackouts when there’s winds or thunderstorms or just stray branches is the real perk.

Interestingly, underground lines aren't feasible in my hometown because of how close the water table is to the surface. Any trench deep enough to bury cables in would have to worry about flooding with groundwater or saltwater in some places.

The water table is so high that not only are there many places where basements would flood 100% of the year, but the majority of homes still have septic tanks instead of town sewage lines, and you can find houses where the lawn has been raised up with 3 or 4 feet of concrete to raise the septic tank to comply with modern regulations to avoid contaminating the groundwater supply.

I’m 4 meters below sea level. We don’t have basements because the buoyancy of the empty space would cause the houses to literally float on ground water. But we do have buried power lines.

You are being lied to.

Slab on grade crew!!

Thanks for the idea, but have you considered spending it all on bombs instead?

There are benefits of overhead lines. They are cheaper to install, maintain, and repair. Diagnosing problems are much easier as well. They're certainly uglier and easier to damage but you don't have to dig up the road to fix them.

Newer cities shouldn't install overhead lines but to have old cities with overhead lines switch to underground ones is very expensive and takes a lot of time, something smaller cities likely don't have the budget for.

You don't have to dig up the roads to fix buried power lines any more than you have to tear up your walls to replace power lines in your house: you install a conduit (basically a pipe) under the road once and if the cable somehow gets damaged and needs to be replaced you can just run new cable through the existing conduit by simply pushing it in on one end and pulling from the other.

Transformers and other non-cable equipment are typically housed aboveground in little boxes or built in to the house, so they're actually easier to maintain than if they were installed aboveground on a pole since you don't need a cherrypicker to access it.

Obviously in a less wealthy small town with existing overhead infrastructure it doesn't make much sense to move it all underground "just because", but if you're already trenching under the road to install water/sewage/gas mains, it won't cost much extra to throw down an additional one or two smaller conduits for running power cables or telephone/cable/fiber lines.

My house has buried lines! ...from the street to the house only... 🥺
