...I had that electric dry shaver.

It sucked

And you cut it through just for this post? How could you?

Needs a banana for scale.

3 million people can't see your post.

I highly doubt this Cable supplies power to 3 Million people.

This one possibly...

I learned today you can get better results on a slingshot

Grounds power?

Only 3 million? Talk about a power play.

This looks like about as much copper as you get off of one 200-300 MW generating unit. Don’t quote me on that.

Op also said “grounds” so maybe he’s talking about an earthing conductor present for some kind of idontknowwhat at a coastal plant like Scattergood Generating station.

this is the second one I’ve seen

Took me a minute

There isn't anything to designate size. However the exterior rubber jacket is reinforced with fiberglass not steel jacketing. This tells me it's a smaller cable and although the insulation is correct for very high voltage, they look too small to handle the required amperage to supply three million people.

😮

More interesting than mild I could ask a million questions.

*used to ground power

FTFY

What is that little auxiliary cable thing?

What does it taste like?

lol there’s no single cable which would deliver that much ampacity and again OP said “ground” so we may never know. Probably an engineer in training just vibing in a new assignment.

Not anymore it doesn’t.

As a journeyman electrician this reads like this is the grounding conductor for an electrical service that supplies 3 million people. That sounds impossible to me

Well sorry to create a minor stir. This is one end of a 1000KV grounding unit. I am not an electrical engineer. I am a subsea navigator. I design routes, not cables.

This does in fact discharge the power that 2-3 million people use an hour.

The link below is the primary discharge cable that then ties into 36 separate grounding vaults, and one of the 3 primary cables that come from the originating overhead lines. US Quarter for a scale.

I've commented a link to add clarity

This cable was installed in a sandy area and did not require steel jacketing. I've commented a link for size comparison. Not an electrician. Just the guy who helped install the subsea cable.

Here is a link to the power line.

Wtf put it back I need to watch my soaps

Where’s the banana?

If I had a dollar for every time someone posted a picture of a cross section view of a power cable on this subreddit recently, I would have two dollars. Which isn’t that much, but it’s weird that it happened twice.

What is this? A power supply for ants?

It doesn't really make sense that they're using multicore cables for grounding. It also doesn't make sense to use insulated cables when you're working with steel towers and infrastructure so I'm really confused by your post. Especially as the wiki article mentions the use of ACSR conductor for the grounding system?

Also it would not be expected for a grounding system to be energized for this type of system unless there was a fault.

Is that before or following use of it?

ever heard of scale ?

This could be any size you want

I'd have thought it would leave the worst razor burn of your life.

Yeah I've weighed things on scales before.

I mean, it CANT be any size. It's this size. I can't make it physically bigger or smaller.
