Reply to comment by Toughduck48 in A Cross Section of the Sub-Marine Cable that grounds power for 3 million People in Los Angeles County by cg1bs

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.

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.
