Needs a banana for scale.

...I had that electric dry shaver.

It sucked

this is the second one I’ve seen

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.

Grounds power?


Quiet_Gorilla9482 t1_j6lseb8 wrote

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


Toughduck48 t1_j6ku72z wrote

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

This one possibly...

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.

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.


689027015 t1_j6lly9d wrote

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.

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.

Not anymore it doesn’t.

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.

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.

Only 3 million? Talk about a power play.


Lofteed t1_j6mt46i wrote

ever heard of scale ?

This could be any size you want


cg1bs OP t1_j6oqukw wrote

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.
