Conductor weight[edit]

"The weight of the conductors is approximately 50 tons." Weight per metre, per-km, per strand, per wire? —Sladen (talk) 12:03, 27 November 2007 (UTC)[reply]

Most likely 50 tons per kilometre for all wires together, which gives a reasonable size of wire for 3 conductors each consisting of an 8-wire bundle (see picture). — Preceding unsigned comment added by Historikeren (talk • contribs) 15:43, 30 March 2012 (UTC)[reply]

50,000 tons of conductor?[edit]

@DCDuring: regarding this edit, what Russian article and what source do you mean. There are only two sources in the Russian Wikipedia article, one is a dead link, and the other does not seem to have any information on the weight of the conductors. The Russian article was changed from the much more believable 50 tons to 50,000 tons without adding any references or explanation. I would surmise that this is a simple error. The English page was changed to match the Russian page about a year later after also having the weight at 50 tons for some time. That is a very bad basis on which to alter numeric data and I will revert it pending production of a source. SpinningSpark 00:00, 17 August 2016 (UTC)[reply]

Is this being reviewed only by innumerates? A plausibility check would have 50 tons yielding a ridiculously small cross-section for multiple multi-conductor high voltage lines running hundreds of miles. See photos of the line and check the actual approximate diameter of such conductors on Commons. The lower number is embarrassingly stupid, discrediting WP. DCDuring (talk) 02:21, 17 August 2016 (UTC)[reply]

The Russian WP article currently (no pun) presents the weight as "50 тыс. тонн.", ie, 50 thousand tons, or about 500 tons per kilometer or 500kg per meter. That may seem high, but 0.5 kg per meter? The total system apparently consists of multiple conductors supported and protected by additional cables. Simply counting the number of visible cables should have made the smaller number wildly implausible. A single cable for such a transmission system with insulation weighs at least about 50 kg/m. Consequently, multiple conductors and supporting steel cables could easily weigh 500kg/m. I don't have definitive sources but the English WP article looks like a direct translation of the Russian one. I hope the translator checked the sources. If you can't accept the Russian article citations, then delete the number. Hell, delete the article. DCDuring (talk) 03:20, 17 August 2016 (UTC)[reply]

If the translator did check the sources, and the number had been there, then it was 50 tons, because, as I said, that is what both articles originally stated. However, I don't believe that the number came from any referenced source. I had already checked the Russian source and the word "тонн" is not in it anywhere, nor is the numeral "50,000". @Wtshymanski: pinging a user who actually knows something about high voltage systems.

Here is a link to the archived copy of the Russian deadlink in the Wayback Machine. No tons or weights in that article either. SpinningSpark 18:25, 18 August 2016 (UTC)[reply]

I've deleted the sentence with the unsupported number. Though 50 tons is way too low. 50,000 tons seems high unless they are talking about the total weight (including insulators, connectors, spacers etc) suspended from the towers, or even the total weight including the towers. DCDuring (talk) 19:00, 18 August 2016 (UTC)[reply]

The context of what ruwiki said originally was that every single conductor had weight about 50 tonnes. It seems that it was interpreted that all conductors weight together 50 tonnes and after that it was corrected to 50 thousand tonnes to sound more logical. Unfortunately this edit by user:Silver7487 did not provide any edit summary to explain that edit. It seems that 50 tonnes per a single conductor comes from this source (in Russian). Beagel (talk) 20:40, 18 August 2016 (UTC)[reply]

Seems I was incorrect. It probably means that 50 tonnes is a weight of conductors between the spans per this source (Вес проводников между пролётами приблизительно 50 тонн). Beagel (talk) 20:57, 18 August 2016 (UTC)[reply]

By what might be a coincidence, it would take about 1,000 spans (of typical length: 4-500m) to cover the 432 kms of the subject UHV line, so the total weight would be on the order of 50,000 tons. The weight per meter would be about 100kg. It is all plausible given that there are probably two three-phase circuits, needing 6 conductors, ie, ~17kg/m for each. Should there be only one three-phase circuit each conductor would weigh ~34kg/m. One can also see the lightning protection (also a conductor) at the very top of the outside towers. I don't really understand all of the other cables, but they cannot all be transmitting conductors. Some are probably ground fault protection. DCDuring (talk) 01:52, 19 August 2016 (UTC)[reply]

I am writing through a translator. If AS 400/51 (in russian АС 400/51) wire, then: 1400 km * 3 phase * 8 wires * 1490 kg/km ≈ 50000 tons.WikiErdos (talk) 18:01, 8 August 2021 (UTC)[reply]

Issues of High Voltage[edit]

It would be nice if the article mentioned some of the issues faced by high voltage transmission lines. Naively, higher voltage is better due to lower resistance losses, but at the high end, you start losing energy due to other factors such as corona discharge. 37.49.69.232 (talk) 10:47, 18 December 2022 (UTC)[reply]

This is discussed at overhead power line. We don't need to repeat material that is generally applicable in every article about an individual line. SpinningSpark 11:55, 18 December 2022 (UTC)[reply]
