File permission problem with File:ACCC conductor in Moore Tornado.jpg

Thanks for uploading File:ACCC conductor in Moore Tornado.jpg. I noticed that while you provided a valid copyright licensing tag, there is no proof that the creator of the file has agreed to release it under the given license.

If you are the copyright holder for this media entirely yourself but have previously published it elsewhere (especially online), please either

• make a note permitting reuse under the CC-BY-SA or another acceptable free license (see this list) at the site of the original publication; or
• Send an email from an address associated with the original publication to permissions-en@wikimedia.org, stating your ownership of the material and your intention to publish it under a free license. You can find a sample permission letter here. If you take this step, add {{OTRS pending}} to the file description page to prevent premature deletion.

If you did not create it entirely yourself, please ask the person who created the file to take one of the two steps listed above, or if the owner of the file has already given their permission to you via email, please forward that email to permissions-en@wikimedia.org.

If you believe the media meets the criteria at Wikipedia:Non-free content, use a tag such as {{non-free fair use}} or one of the other tags listed at Wikipedia:File copyright tags#Fair use, and add a rationale justifying the file's use on the article or articles where it is included. See Wikipedia:File copyright tags for the full list of copyright tags that you can use.

If you have uploaded other files, consider checking that you have provided evidence that their copyright owners have agreed to license their works under the tags you supplied, too. You can find a list of files you have created in your upload log. Files lacking evidence of permission may be deleted one week after they have been tagged, as described on criteria for speedy deletion. You may wish to read the Wikipedia's image use policy. If you have any questions please ask them at the Media copyright questions page. Thank you. Sfan00 IMG (talk) 19:13, 5 September 2013 (UTC)

Can you please check out my question on ACCC ?

Hiya Dave, My name’s Dave as well. Re: https://en.wikipedia.org/wiki/ACCC_conductor?wprov=sfti1 In the paragraphs in the WIKI page, I’m curious if there’s a typo where it says: ‘but has about 3% less electrical conductivity’ However, in the following paragraphs, it claims 30% and then 31% differences in conductivity. Is this correct or should the 3% be 30% ? I just thought it’s weird that the paragraphs seem to offer contradictory information. I can be reached at: Email: gto3deuces@gmail.com OR Text: (610) 842-7905 Thanks to anyone who understands this engineering ! WIKI article referenced text: Softer, fully annealed aluminium can be used for the conductors. ACSR cable uses stronger non-annealed commercially pure aluminium which contributes to the cable's tensile strength and improves sag and pull-out under ice load, but has about 3% less electrical conductivity and limits the maximum operating temperature.[4]:12 It has a much lower coefficient of thermal expansion (CTE) (1.6 ppm/°C) than ACSR (11.6 ppm/°C).[5]:23 This lets the cable be operated at a significantly higher temperature without excessive sag between poles. The first two factors result in roughly 30% greater conductivity than an equivalent ACSR conductor, allowing 14% more current to be carried at equal temperature. For example, 1.107 in (28.1 mm) diameter ACCC "Drake" conductor at 75 °C has an AC resistance of 106 mΩ/mile,[6] while equivalent ACSR conductor has an AC resistance of 139 mΩ/mile,[7] 31% higher.
