Talk:Power cable

Household wiring

My 30 Amp oven/stove is connected with #10 AWG copper wires, about 5 square mm. My stove runs on 240 V, just like a UK cooking appliance. What wire size would be used in the UK? According to table 9D2 in the 15th edition of the wiring regs, to get a 30 amp capacity you would use 6 square mm cable (themoplastic insulation, non-armoured, installed in a wall). So UK regs require *heavier* wires in this specific instance than do US adn Candian rules. It's not generally true to say that US wires are *always* heavier than UK wires. --Wtshymanski 16:47, 15 December 2005 (UTC)

Move to conduit

If anyone ever writes electrical conduit this information should be put there: By comparison, most conduits are arranged so that their contents may be "pulled" or removed from an opening in the conduit, whereas conductors in cables are bundled tightly within the jacket, etc, as a unit. Cables undergo many stresses when being installed, that of tension, and the insulation being crushed at the bends of the temporary pulleys or at the bends of the raceway. Lubrications are used in conduits ahead of the cable to provide less friction, but these must be compatible with the nonmetallic materials of the cable -- a froth of vegetable-oil soap and water is good.

Ampacity Derating

The derating factor is a major issue particularly in the field of circuit protection - protection against fire that is, to keep electrical circuits operational during a fire. This is of primary importance in nuclear reactors, whereby the idea is that during an accidental fire, operators in the control room must be able to switch off an operating reactor to prevent accidents. Vendors for fireproofing methods not only battle each other in terms of the price per m² installed, but also on the derating factor. Mitigation of the derating factor can be had by installing intumescent windows in one's fire barrier wrap, so that the electrical circuits can radiate extra photons off during normal operations. During a fire, of course, the intumescents simply shut. The first major passive fire protection scandal to hit the US nuclear industry dealt with a product whose bounding was not based on product certification. This has resulted in major remedial work in the US's 100 odd USNRC[1] licensed nuclear reactors.

Transformers?

I've been looking for something on Wikipedia about the big ac=>dc conversion blocks that are on the end or middle of many power cords. What in the world are these called? ~ Booyabazooka 20:21, 19 May 2006 (UTC)

Ah, looks like I've answered my own question, with the discovery of the power brick article. There should probably be a reference to that, but I'm not sure where to include it. ~ Booyabazooka 20:33, 19 May 2006 (UTC)

See also Power supply; looks like we've got some merging to do. "Wall wart" is another common term for these things.

"Romex"

my information is that Romex was a trade name by General Cable. product made in their Rome NY plant. —The preceding unsigned comment was added by 64.24.209.223 (talk • contribs). Romex is a Southwire Co. registered trademark for their NM-B product line. — Preceding unsigned comment added by 72.152.74.109 (talk) 01:46, 30 August 2011 (UTC)

Help with cable types

Anybody know what is armoured radial field impregnated paper insulated cable? and armoured none-radial field impregnated paper insulated cable? —The preceding unsigned comment was added by 58.187.132.155 (talk • contribs).

Is capsicum used in the shield to discourage rodents from chewing it? —Preceding unsigned comment added by Qi4u (talk • contribs) 04:13, 24 May 2008 (UTC)

Edit conflict

I'm getting too woozy to sort out whether your edits or mine make more sense here, but we were having an edit conflict in the one section. Having other open edits to backup to, I cede the matter to you, but note I probably undid most or all of your changes in that "cable names" section. Sorry, but don't see well enough right now to reconstruct, and my version was good enough once I fixed my own "counts error" in table. Glad to see someone is tending the "store". Good luck! // FrankB 05:02, 1 July 2008 (UTC)

I'm pushing back to return to the version containing my attempts at clarification. I corrected a number of grammar problems: one or two spelling errors, possessive "it's" corrected to "its", eliminated the use of the term "radiological" when it was clear that "sunlight" was what was intended, the elimination of repetition of the same root word in a sentence (such as defined...define and regulations...regulate); in short, a reworking to make it flow better. Some technical additions and subtractions were part of the deal, too... I added a bit about Yellowjacket-style modular cable protection (with reference) and I changed a number of instances of "naked" to "bare" or "uninsulated", terms I think might be in wider usage. Check it out when you have a chance, and make sure I didn't change the precise meaning of anything to be wrong. Cheers! Binksternet (talk) 05:17, 1 July 2008 (UTC)

Modular cable ramps

I put this little bit into the article where cable sheathing under conditions of mechanical impact are being discussed: "Portable protective cable coverings made of interlocking sections of heavy plastic can be used for temporary power cables exposed to foot and vehicle traffic." The reference is a patent granted for Modular cable protectors. It was removed by User:Wtshymanski for unstated reasons. Perhaps it would be more palatable if I clarify that such cable protectors make it unnecessary for cable sheathing to be of greater impact resistance? FYI, I use such modular protectors all the time in my work as a sound engineer at public events. Five four-ought or smaller three-phase conductors with SO sheathing are often routed through a series of these protective devices where they cross paths with attendee traffic patterns. The leading manufacturer is Yellowjacket, but other makes and models abound. Binksternet (talk) 16:53, 1 July 2008 (UTC)

I remvoed it because it didn't seem to illuminate the topic - there's lots of ways of protecting cables, none of which are central to the construction of the cables in and of themselves. I suspect more cables are protected by a pair of wooden planks on a job site than by any number of patented plastic ramps. --Wtshymanski (talk) 20:39, 1 July 2008 (UTC)

Overhead Cable?

Correct me if I'm wrong, but the term cable implies underground. Overhead (OH) lines are referred to as wires, whereas underground (UG) lines are referred to as cable. 155.13.48.8 (talk) 22:53, 24 August 2010 (UTC)

So what's a triplex? Three wires, two of which are insulated, in a cable - and they run overhead. *Who* refers to "wires" overhead and "cables" underground? --Wtshymanski (talk) 15:46, 25 August 2010 (UTC)

High Voltage cable and power cable

can't we merge both articles. I think it is quite the same. —Preceding unsigned comment added by 138.246.7.7 (talk) 20:58, 10 March 2011 (UTC)

Power cable seems very vague, and touches, but does not exp[lain a number of different cable types support merge. Dougsim (talk)
