UG line transmission high expensive

ALL POWERLINE MUST MAKE UNDER GROUND WITH GOOD MANPOWER.

Were I live there is no power lines and asked why they said there underground.

Life expectancy ? see what storms & fires do to your local town and just ask the insurance companies how much the damages & repairs cost vs going underground for a little added cost up front and nowadays with better materials and equipment even internal grounded expansion fittings are watertight eliminating the cost of bonding jumpers and the risk of failure and safety for longevity. Check out a company called Bams fittings and see the new technology that's available now and one of the reasons we should continue to go underground for sustainable energy vs overhead. And yes there are certain areas that need to continue with overhead this we know. But if you're gonna go underground please use new technology not old grounding technology it'll also save money and time installing it to help the bottom line in cost. Research it

Underground is nice but the cost and thermal ampacity limits restrict it's economical ideployment. ACSR open air conductors are far better (thermally and deployment cost) Undergrounding. Makes more sense for 12/21 KV in developed areas. Our local utility has an ongoing battle keeping 30+ year old direct burial cables operating. When we lose an aerial 12KV feeder it's less than an hour for restoration... RU feeders can be several hours to locate the fault and dig up the line...

Nice video. Explains a lot. I remember before I went to DC for the first time, my boss told me to notice how all the power lines in the city were underground

Thank you mister!

i do not belong to the understanding minds, but iam just depart from that , kindly allow to express our pain general electricty can be done underground y basic electricity supply highly a great pain to making green , unless underground electricity wire comes only then we can think of plantation and support life expectancy of human with oxygen today oxygen tax will be the future business in india solar and electric vechile still not in practice how for india still failing to impose y dealer and distributor still places to make business with fuel vechil the prices of solar vechile itself raised that is shame to indian gdp or lower end state like southern state gdp country shaming livilyhood when certain amount of oxygen itself insufficent in the earth

“At times, burying transmission lines make sense.“ But doesn’t explain why...🤦‍♂️

I have experience 7 years jointing work 132kv 220kv 400kv Your Company any vacancy Please tell me

Quite

I read 4.5 ut micro tesla and 350 v/m volts per meter in my house from power lines over the street that I live on. Are these safe levels?

So many different designs of tower in the US its quite bewildering!

What gauge is the wire?

Anywhere in the US, as I know it, don’t allow underground transmission lines. I think it’s because of the big Electromagnetic Field (EMF). Underground lines tend to be below 20 feet below the surface. When we walk near or above one of those lines, we can be severely harmed by the EMF radiation. *Did you know?* Transmission table Voltage = radiation (EMF) 20-50kV = 22-77ft 50-90kV = 77-103ft 90-99kV = 103-119ft H-shape frames ••••••Transmission level 2••••• 99kV-100kV = 119-121ft 100kV-130kV = 121-199ft 130kV-190kV = 199-213ft 190-199kV = 213-222ft Transmission poles (200kV-210kV) and pylons (211kV+) •••••Transmission level 3••••• 200-210kV = 229-268ft •••••(Pylons) Transmission level 4••••• 211-240kV = 280-344ft 241kV+ equals 351ft+

SHORTER LIFE EXPECTANCY?! Overhead lines change temperature faster, change temperature MORE, are exposed to wind, ozone, UV, water, ice and snow. They are exposed to MORE animals, especially squirrels and birds Loss-costs are, on average, 2.8% for underground, vs 37% for overhead. 70% of line failures are weather-related, 11 percent are animals on overhead cables/poles/transformers... Underground cables bring those externality risks down by at least an order of magnitude!

Hi ! Can I ask Permission to Download your Video as our reference in our Research in our School ? tnx

Overhead transmission lines running near houses causes leukemia in the people of those houses, especially kids. Under ground transmission lines can be shielded and made safer but the power company doesn't want to afford the cost.

Overhead cables not being insulated or very thin insulation are kept cool by passing air, underground with thick insulations cables heat up when passing a lot of current for lengthy times thus resulting to very decreased life of the plastic insulation.

Here in Florida, underground transmission lines will never happen. Floridian rate payers don't want to pay the extra cost. If anything, FPL is upgrading the wooden transmission poles to steel ones.

But for outside powerlines you need to build and install some "steeltowers" and it needs a lot of time to install the lines in that height. I could imagine doing a simple installion for underground lines. No underground concrete "houses" to join the lines. One machine does it all. 1. escavate 2. lower powerline 3. put concrete in 4. join with the next line 5. cover, close and finish. How can that cost more ? And why underground lines have just the half lifetime like the outside lines ? Should be inverse or not ? Undergroundlines are safe from wheater, air, water, wind and sun.

it take up space too . planes that need to land in emergency can't do so because of stupid tall towers in their ways , expecting them to find a BIG EMPTY LAND ? that cause 90% of air crash , i will suggest that using underground cables with tunnel beside them , while if the cable is damaged , use a computer to scan and ask workers to use a vehicle to travel to it . it will be much easy !
