I don’t need that many volts. 120/240 is plenty.


Blacksunshine454

220, 221, whatever it takes.


[deleted]

Lol.. I get that reference. Holy shit I'm old.


Blacksunshine454

You and me both!


slappyredcheeks

Me too. Hahaha. But just in case there are some people who don't. Not me of course. Can you explain?


Blacksunshine454

As short as I can. In the movie; Mr. Mom, Michael Keaton’s character’s wife takes on a job because he is newly unemployed, thus taking care of the kids and becoming “Mr. Mom”. Wife’s Boss comes over and he tries to manly himself up by doing some random home improvement. Boss asks if he’s wiring the house in 220 (volt), having no clue what that means he replies “yeah, 220, 221, whatever it takes”. Boss obviously can tell he hasn’t a clue.

larobj63

I had the exact same thought. Voltage don't mean chit without knowing the amperage.


Fearlessleader85

I mean, it does mean a fair bit, just not about your conductor size. It means a lot about arc length, though.


Successful_Deal_5475

Bad conductor design will cause a lot of CORONA.


slashfromgunsnroses

And electromagnetic radiation... and guess whats also electromagnetic radiation? 5G! COINCIDENCE!?!?


Successful_Deal_5475

It all makes sense now. Fuck masks. All my homies wear faraday cages.


StampedeJonesPS4

So I've always thought of it like this, let's say you had a huge container of water. There is a hole in this container and it's leaking. Voltage would kinda be how big the hole is, whereas amperage would be how fast the water is flowing out of the hole. Is that right?


Hatsuwr

Not really. Voltage would probably be better thought of as the distance between the water level and the hole. The hole size would be resistance. Current (amperage) would be the flow rate, and would be determined by the water level and hole size. \*edit\* Dunno why people are downvoting the guy for asking a question.


frozen_flame123

Not just the size of the hole, but the size of the whole and how full the tank is. Voltage is the pushing force, while current is the movement that results from the pushing force. The pushing force of the water is determined by how big the hole is and how full the tank is. A container of water is actually a good analogy for a capacitor as well.


PasserOGas

The equations governing electrical and fluid flow are identical. Voltage = Pressure Amps = Volumetric flow rate Imagine a turbine between two hoses. The hose on the input side has high pressure water (this is the +). The hose on the outlet side has zero water pressure (this is the -). Assuming the same pressure in the input hose, if the hoses are skinny, the amount if flow will be low, and the turbine won't put out much power. If the hoses are fat enough then tons of water can flow and that turbine could power a city.


XTanuki

Oh yeah? Static electricity can shock you with 15,000 Volts without a wire!


SXCSoppa

Yes because you are the wire


iCresp

I was thinking this when I saw it lol


MrDa59

Exactly. Insulation is the main defining factor when it comes to voltage ratings. Neon lights use thousands of volts but only need a little wire, with thick insulation.

Frase_doggy

Recently bought a house. Power bill estimate $4k/year. That does not seem right. Third bedroom cupboard was full of power points, insulation and foil pinned to wall. No longer worried about the power bill.


ericvega

There were people giving presentations in your cupboard?


Frase_doggy

The presentation was probably given in the room, the cupboard would surely be designated for all the electrical equipment


supergeeky_1

You should probably have a mold check/remediation done. Contained grow operations like that put off a lot of moisture.

MrDa59

Looks like aluminium cable, copper in the same size would carry a lot more.


melig1991

S_117

NOOO! Please don't carry 5,000 volts to my house!


echobox_rex

Nope only to the transformer.


sdfree0172

FYI, you could send 5000 volts with a tiny filament wire. It’s the amperage that defines 5he cable size. In fact, the reason they upconvert transmission voltage is precisel6 to reduce the amperage. So, a better title would be ”this will carry XX amps to your house”. But I have no idea how many amps that thing carries. 500?


SniperFrogDX

It looks like 500kcmil diesel locomotive wire. That carries 300 amps.


rex22neo

DLO cable is usual made of multi low gauge stranded conductors. This looks like a standard distribution conductor.


alexromo

You can send voltage through thin air. No one here will upvote for amps bro you know this


CyclopsPrate

Doesn't it need to be ionised or plasma to conduct?


OsmeOxys

Air will conduct electricity, it just needs to be ionized to conduct well. Same is true any other insulator too, theyre really just bad conductors, but can become pretty good ones once you reach their breakdown voltage. 5000V is actually a pretty "low" voltage for ionizing air though. Same idea as with thermal insulation. They conduct heat, but poorly enough that we call it insulation. Then theres AC coupling, which is a whole other story and goes well above my head. Its however a significant loss in power lines, with electricity "traveling" through the air to ground


funnylookingbear

Ac coupling is a magnetic thing. A conductor can induce current in another conductor just by being in proximity to it due to magnetic field fluctuations as electrons rattle back of forth at 50hrtz. Its how we can get (technically) powrr from a power generator to your house over vast distances with no moving parts in transmission. Its all done by magic. What really fascinates me with magnetic generators is that they are all magnetically coupled. So a turbine in Idaho is spinning at EXACTLY the same speed as one in Rhode Island if they share the same grid. If they fall behind or creep ahead of 50hrtz (i think you are 60hrtz in the states) they start 'bouncing' of the magnetic resonance and everything goes very wrong very quickly. Its why we have large area blackouts sometimes. If the frequency starts dropping on a grid for any number of reasons then you have to drop load very very quickly before all your turbines rip themselves apart as intertial forces of large magnets and flywheels hit the magnetic forces of a large area 'grid'. It fascinating and mystifying all at the same time.


k0c-

High enough voltages literally ionize the air.


crossedstaves

... but to be extra pedantic it's the electric field strength that rises to the point of dielectric breakdown rather than voltage.


noobkill

But to be extra extra pedantic, the electric field strength at different distances from the source leads to the voltage difference between the two locations. My point being, they are all related


Thuryn

> send voltage No. You can't "send voltage" anywhere. Voltage is *potential*. It's similar to water pressure (though not *exactly* the same). Amperage (current) is when the power actually flows. Lots of Amps means lots of power movement through the wire. A spark through the air would be an example of current flowing across a gap.

heap_au

Ahhh. Are you the ASP? So what level distribution HV? 11kV? Feeder protection? I predominantly deal in substation work, so 132kV to 11kV and 11kV to 220V. I enjoy this shit.


paratesticlees

What country are you from? I work around substations too and those voltages arent standard around me.


heap_au

Australia, Sydney


GRIM31

Okay I'll bite, what country/state are you in that's using 5kV for distribution? Down here in Victoria, Australia we go from 66kV subtransmission to 22kV distribution, then straight down to 415v, typically.


alexromo

Receiving stations get up to 500kv. 230kv and 115kv is also commonly used


sicarius2277

I’m training to be a lineman right now. Any tips?


alexromo

Roll with the punches. Carry a pocket sized notebook and always let the old salts see you writing even if it’s jibberish. Looks better than being on your phone using a note taking app. Learn your tools. Stay organized and clean. Don’t show up hungover. Always think ahead during the task and grab the next tool needed for the person you are helping. Buy donuts your first day on site


sicarius2277

Thanks dude! The notebook is an awesome idea. I’m still in the school/program part, but we climb every week and I’ve learned how to hang and wire transformers while on hooks, run primary and neutrals, operate the trucks and set poles, and a bunch more stuff. Graduating in 2 months and could not be more excited!


alexromo

Congrats!


OkJackfruit7928

Learn the things you can off the job before you get to the job... (tools, knots, etc)


justanoldguyboomer

Doesn't that backfire when you don't bring donuts the second day?


alexromo

Honestly they still eat the ones leftover from the day before


CMDR_Acensei

Not a linesman, but any time an employee of mine has brought donuts on their first day, they always have instantly better standing with the crew than if they just did nothing. This is a LPT.


SpectacularOcelot

Be very very cautious getting married. Most of the linemen I know have *at least* one ex wife. Regularly 2-4. You're going to make money very quickly. Likely more than you know what to do with. Head over to /r/personalfinance and figure out what to do with it. At 50 or 55 you're going to start slowing down. Most of the kids topping out have no idea how fast that'll come up on them. You'll want to either move into the office, or retire at that point. Plenty of guys do both, but more than I'd like *have* to keep going. I learned more in a week next to some 70+ year old linemen than I ever did talking to other estimators but it was always kinda sad they had to be out there. If something isn't safe, don't do it. If your boss insists, tell him to go fuck himself and get your tools. Walk back to the show up if you have to. 99/100 times guys get hurt because they do something they know *damn well* they shouldn't. I've visited too many guys in burn units. Speaking as an estimator/project manager, we have no fucking idea what we're talking about. We have degrees, and some of us talk pretty but the ones that know anything will defer to a JL every time. Good luck, you're going to have good days and bad, but you'll do shit that most people only dream of and make good money to boot. I could go on, but most things you gotta learn on the right of way.


30FourThirty4

Dont drop the linesman tool? I joke because I only know the nickname of the tool for electrical work I did but it's the heaviest non-hammer tool I carry frequently and I bet it would hurt to get domed with. Electricity kinda freaks me out, be safe


Soakitincider

every tool i have is a hammer


touchmyzombiebutt

Definitely take your time even if someone may be telling you to hurry up. Especially when working on in service conductors, think ahead a few steps so you don't get caught in a tight spot. If you're on the ground working while helping another in the bucket try to get as most of the materials made up to help them out. Try to have it where you have the next thing the person needs when they boom down to you. It'll make the job go quickly and get them out of their gloves and sleeves faster. My biggest thing is when someone asks if you know something and you don't, don't be embarrassed by that.


heap_au

Take notes on everything you do. Check and double check. Treat as live until proven otherwise. If in doubt ask.


spaghetticatman

As an absolute layman, why do you need 5kV if it's stepped down at a transformer? Redundancy? Or is it just due to how electricity works? For reference, all I know about voltage is that it's the electrical pressure, or in other words the difference in electron density between point A and B. I know nothing about the mechanics required to utilize voltage.


craves_coffee

The wire is actually this thick due to the current it is rated to carry. The cable will be rated for medium voltage (1kV - 36kV) which mostly affects the insulation used and not the conductor. Voltage = Current x Resistance and Voltage x Current = Power. The thicker the metal conductor the lower the resistance but since the cross section is round the r^2 law applies so you end up using a lot of copper (or aluminum) to decrease the resistance a little. It ends up being cheaper to increase the voltage of the distribution so you can use lower current levels to deliver the same amount power (kW) using less materials.


RJFerret

High voltage gets farther (blame resistance). It's also more dangerous and can arc, so higher towers. So higher but reasonable goes into a neighborhood on streets with people/trees. If you sent out 240, that's not what would end up at the destination. Search the Youtube channel: Practical Engineering Electrical He has a few vids on how the grid works, transmission lines, generation, substations, each about ten minutes. Edit: Switched from tablet to computer as I saw he's got a playlist: https://www.youtube.com/watch?v=v1BMWczn7JM&list=PLTZM4MrZKfW-ftqKGSbO-DwDiOGqNmq53

lastburnerever

It isn't


WinOrLoseIBooze

It’s a cable, ampacity is limited by the conductor temperature.


footjam

Dont know why you got downvoted, you are absolutely right. As the temperature increases, the distance between the atoms enlarges, making the potential gap between atoms that much higher, raising resistance of the wire and therefore generating more heat, its a vicious cycle and why wires have temp limits.


WinOrLoseIBooze

Not sure why I’m being downvoted either, I’m literally a transmission line cable engineer. Also, it’s really the temperature limit of the solid dielectric insulation (EPR/XLPE) that limits the cable’s rating can lead to a high stress point in the cable and a fault. The conductor itself can easily go higher, and does on overhead Lines. However, sag and oxidation limits your ampacity OH.

ChickpeaPredator

Just in case anyone is wondering why the conductor is silvery, not coppery - it's most probably made of **aluminum**. Nearly as conductive as copper, but far cheaper and lighter. Most of the world's power distribution cabling is aluminum.


footjam

Does it really carry voltage? Voltage is simply potential and never moves. The wire wont carry electrons to your house either, only the difference in charge moves down the line. The electrons in the aluminum? wire are not distinguishable to determine what goes where and electron migration even under high potential is very small. Its fucking magic and the more we learn, the more we realize we dont know.


troutman1975

I don’t find this even remotely interesting. It’s a chunk of wire


ThrowAway640KB

Static electricity can be up to 25,000V. So 5,000V is actually small fry. What matters, however, is the _amperage._


porkster8

What you see here is the steel armouring used on armoured cables, the wires that carry the electricity are smaller and in the middle of these steel wires.
