Talk:Aerial cable

Wrong name?

I am not sure what the original intent of this article was. I lived in England two years and learned that what Americans call antennas in England were called aerials. Did the author intend to write about antenna transmission cable; i.e. coax? (PeacePeace (talk) 00:29, 25 September 2017 (UTC))[reply]

Insulation

I suspect the name confusion, "air cable" vs "aerial cable", arises from international dialect differences and/or translation. In my home area (north-eastern United States), I've never heard the term "air cable" used. Lines hanging above ground are always "aerial cable" or "overhead cable". Most of the article appears to have been written by a European; terminology often changes slightly when crossing the Atlantic. Nothing wrong with that, but we should make it clear when terminology differs. Which brings me to:

In my experience, in the US, the terms "aerial cable" or "overhead cable" most definitely do not have any connotation of "insulated conductors". Overhead power lines are the biggest example; they are considered aerial but are not insulated. Perhaps things are different in Europe? Perhaps the insulated nature is attached to term "air cable" in Europe? Could anyone (especially the original contributors) comment on this?

Merge/Replace with Aerial Bundled Cable page

This page seems redundant with the Aerial bundled cable page. I believe the terms "aerial bundled cable" or "aerial bundled conductor" are more generally used than "aerial cable" in the power industry; see for example IEEE articles doi:10.1109/CEIDP.1996.564714 or doi:10.1049/ic:19950297.

I deleted a section which probably contains error and has no source indicated.

The article said:

"Aerial cables are commonly used for the replacement of overhead telecommunication lines as they can be installed on existing poles and make the facility more reliable. Telecommunication systems running along power lines or aerial tramways are often built as aerial cables as they can be easily installed on the pylons or tramway support towers. However, these cables must be designed for higher forces as span lengths are longer.
"For reasons of electromagnetic interference aerial cables running along power lines are most often of fiber optic types. As these are dielectric, it is even possible to install them directly in the conductors— see optical ground wire.
"Aerial cables are also used sometimes for power transmission from the transmitter building to the antenna at radio stations."
I deleted the above as it has no source indicated (no reliable source) and it appears to contain error. It says, for example,
"As these are dielectric," but the antecedent of "these" is unclear. As the article stood it was saying that optical fiber types are dielectric and can be installed in the conductors. Did the author mean to say "along side the conductors? I don't think that optical fiber types are inserted into copper wires, as there is probably only copper inside copper wires.
As to transmission lines from radio transmitters to antennas, so far as I know this would usually be coaxial cable, though 300 ohm twin lead and 600 ohm balanced ladder-line has been used by Hams. And while the radio waves do have power, I don't think one usually calls them "power lines." Likewise, since this article seems to be about power lines, I doubt that fiber optics belongs in this article. (PeacePeace (talk) 00:23, 25 September 2017 (UTC))[reply]

Logical Division of the Topic "Power LInes"

I came to this article from the article on underground power lines, which is an alternative to hanging power lines from poles.
I remarked when I lived in England how we had not had any power outages while I was there. Yet in USA power outages are routine. I was informed (as I recall) that the British buried their power lines for World War 2 to make them resistant to bombing. Since then I have regarded our hanging lines as low civilization, what with power outs -- right now (Sept 2017) I believe that all of Puerto Rico is without power after a hurricane.
This article came to me as a 3rd alternative to hanging power lines vs burying them underground. But I don't see this as a proper division of the topic of power lines. This article seems to concern coated insulating of hanging wires (with plastic, rubber, etc., as wires in a single cable) vs hanging them separated using separation in the air as the insulation. It seems to me that very high voltages have to be separated by distance and the covering of the lines with plastic by itself won't do much good. That being said, I am not sure how to heal this article & juxtapose it with the article on burying power lines. (PeacePeace (talk) 00:41, 25 September 2017 (UTC))[reply]
