Talk:Submarine power cable

Comparative cost data

There is some comparative cost data on the cost of constructing submarine power cables vs. overhead AC cables in the New York Times source that I used to cite several other article claims today. I've not yet taken the time to stub out a cost section for this WP article. This is yet to be done. Anyone have other sources? Worldwide project cost data?

Design Technologies

The Design Technologies section is not about submarine power cables specifically but about AC vs. DC electrical power transmission. While a quick overview of electrical power transmission and the reason for using AC or DC could be helpful but not useful to viewers this section takes up the bulk of the page and is not directly relevant to submarine power cables. — Preceding unsigned comment added by 184.1.216.95 (talk) 18:57, 6 May 2015 (UTC)

more relevant when surrounded by a conducting medium in which current can be induced by AC, perhaps? Midgley (talk) 09:31, 17 July 2019 (UTC)

I have put the former content of Design Technologies (comparison of AC and DC) into a new chapter (Selection of AC or DC), and added new content to the design chapter. I suggest to remove the old content from this article.(comment added 4.1.2017 by Worzyk) — Preceding unsigned comment added by Worzyk (talk • contribs) 21:27, 4 January 2017 (UTC)

Round for higher voltages

"For voltages ≥ 12 kV the conductors are round. " That is a nice narrative hook which could do with a link to explanation with perhaps 6 words briefly saying why. I suspect it is due to leakage and breakdown off corners, but don't really know. Midgley (talk) 09:33, 17 July 2019 (UTC)

For high voltage cables the conductors are artifically rounded by a hull made of conducting (black) polyethylene so that the electric field is as smooth als possible. Goetz48 (talk) 12:25, 17 December 2022 (UTC)

power direction

It seems that the tables are not consistent in the direction of power transmission. At least for the Vancouver island links, the AC table is left to right, while the DC table is right to left. Also, the DC table gives the body of water, and the AC table does not. Can the tables be consistent in direction and body of water? Gah4 (talk) 20:29, 22 September 2022 (UTC)

Cables are always suited for transmission in both directions, the DC/AC converters in most cases too. AC connections are always capable to work in both directions. Goetz48 (talk) 12:14, 17 December 2022 (UTC)

Power

It would be nice if the rated power would also be mentioned in the tablesGoetz48 (talk) 12:29, 17 December 2022 (UTC). That is the most relevant data for a power connection. Goetz48 (talk) 12:28, 17 December 2022 (UTC)
