Talk:Litz wire

message: Twisting wires together does not have the same effect. It is important that a wire be on the outside of the cable for a small distance but also be in the center of the cable for a small distance. Just twisting a bunch of wires together would keep a small number on the outside of the bunch and not significantly improve the high frequency conductivity.  —Preceding unsigned comment added by Glrx (talk • contribs) 22:37, 4 December 2007 (UTC)
replies: text: It's certainly true that simply twisted bundles have the problem you describe.  However, to me, weaving implies something like braiding, in which the strands are interlocked in some way, rather than the multi-level twisting schemes used in most litz wire, as illustrated for example in the New England Wire Catalog on the page after this page (The URL for the page I wanted was too long).  Some of that was explained, albeit poorly, in the text you deleted.  I'm tempted to revert, but will wait until I have time to try to make it a little better. Note that truly braided or woven litz wire is used--it's just less common than multi-level twisted wire. Ccrrccrr (talk) 02:22, 5 December 2007 (UTC)
thread_title:  Litz Wire is not simply Twisted wires

message: Anyone care to guess what this means?
Litz wire is one kind of stranded wire, but in this case possible material fatigue with its associated danger of complete wire breakage is not a reason for its use.

message: A chart or graph showing the effective conductor size or relative ampacities as a function of frequency might be helpful.  I haven't been able to find anything like that on line, though.  Maybe the people who edit the Skin effect page might know where to look?  --W0lfie 22:49, 18 January 2007 (UTC)

message: Two other problems with the recent edits:
* The intro describes skin effect in detail but says little about litz wire.  It would be better to describe litz wire in the intro and link to the article on skin effect.
* Terman expression:  Pointless to provide that formula without enough detail for anyone to use the formula.  It would be better to just say "Terman provides a formula but it's too complicated to present here.

message: Having a schematic picture at the beginning of the article looks nice. However, I fear that it is leaving a wrong impression: One sees a just a bunch of parallel wires. Maybe it's better to not show this picture (unless someone creates a modified version, in which you can see that the thin wires are twisted)? 130.83.197.163 (talk) 14:19, 13 January 2010 (UTC)
replies: text: I agree.  We have a huge picture there at the top of the article, and that simply is not litz wire!  I will look to see if I can find a suitable image.  CosineKitty (talk) 17:04, 10 March 2010 (UTC)

message: I am confused by the two sections in quotes below.  First skin effect is explained, with the rational that a conductor should be at least 1 skin depth to minimize conductive losses.  Then moving on to Litz wire, it states each strand is "less than a skin-depth, so an individual strand does not suffer an appreciable skin effect loss."
I was reviewing this article to have a better design understanding of the strand diameter used for Litz wire, and I do not see the consistency in the article.
******** Article Excerpt *********************
Round conductors larger than a few skin depths don't conduct much current near their axis, so the central material isn't used effectively.  When larger area conductors are needed, measures are taken to reduce skin effect. One method is the use of a hollow pipe with a "conducting wall with a thickness approximately that of the skin-depth at intended frequency."

replies: text: Your "rational[e] that a conductor should be at least 1 skin depth to minimize conductive losses" is an incorrect summary. For good performance, the conductors should be less than a skin depth so all the copper is a used for conduction. When the diameter is many skin depths, the interior space is not used.

message: WWVB transmitting station
NIST uses litz wire in the time code broadcasting station WWVB. The station transmits on 60 kHz. The litz wire consists of 6075 strands of #36 (0.127 mm) magnet wire in a cable ¾ inch (19 mm) in diameter. Litz wire is used in an impressive variable inductor. (Hansen & Gish 1995)
This seems utterly obscure, and in addition, I can't tell what the point is. Why not remove it? 178.39.122.125 (talk) 16:39, 26 June 2016 (UTC)
replies: text: Why not leave it? Its obscurity is what makes it such a remarkable example of an application for very large diameter Litz wire. Andy Dingley (talk) 21:56, 26 June 2016 (UTC)
