who invent this gay shit?

Here's your high quality OFC Copper wire... oops looks like copper can corrode easily we better coat it with tin to prevent that...

Copper too expensive? Here's some Aluminum wire but since most of the electricity is carried on the outer layer of the wire, the "skin" well we better coat that with copper to enhance conductivity.

>_<

it's wire that's cheaper than solid Cu and works just as well at higher frequencies. wtf are you complaining about OP? do you like wasting money?

>>2945544 (OP)
weights way less, is cheaper and has almost no downsides
literally combining the good parts of both materials

>>2945544 (OP)
jews, eg. this guy >>2945547 and also this guy >>2945554

>good engineering? jew!

it's important to note that this effect only takes hold in AC applications and there only appreciably at higher frequencies
the fact ut's mentioned for infrastructure-level grid applications is due to the effect being significant at very long distances even at lower frequencies
other anons might come from your explanation thinking it applies to DC

>who invent this gay shit?
Probably chinks or jews... Whoever it was deserves their head caved in. Especially when they are used in jumper cables...

>>2945544 (OP)
Jesus fucking christ I hate them so much in Ethernet cables. We have so many issues just because of them: unreliable signal, horrible performance with POE applications, solid core cables are more sensitive to bends.

Fuck this shit

>>2945556
"Aluminum cables are copper-coated to provide high-frequency conductivity and corrosion resistance while leveraging aluminum's lower cost and weight. The copper coating on the surface takes advantage of the "skin effect," where alternating current flows primarily on the conductor's surface, allowing the less conductive aluminum core to carry the bulk of the current more cheaply. This construction offers improved corrosion resistance over bare aluminum and is a cost-effective alternative to pure copper, especially for high-frequency applications like some network cables."
>i-it's just good engineering, t-trust me
go fuck yourself, moron

>>2945583
that's literally my point, retard
>hurr it's difficult to install
buy a proper crimp tool, poorfag

>>2945586
each sentense ends with "cheap" and "cost effective", dumbass
your point wasn't that

>>2945587
all I'm hearing is cope over not having a crimper

>>2945588
all I'm smelling is your kippah

>>2945589

>solid core cables are more sensitive to bends
I thought it was the opposite

oy vey ive been found out

>>2945613
Solid core is for carefully pulling through walls and that's it. If you make a bunch of cat6 cables out of a roll of plenum rated riser cable because you had it lying around, you'll be in a world of hurt down the line trying to diagnose networking gremlins until you throw out all your cables and start over.

Same for power wiring. Look at lamp cord (stranded) vs NM cable (Romex).

>>2945583
Tell us why pure copper is better, then

>>2945820
first google result "Solid copper wire is superior to copper-coated aluminum wire for most applications due to its better electrical conductivity, higher durability, and greater resistance to heat and breakage, which are essential for safe and reliable signal transmission, especially in high-demand applications like Power over Ethernet (PoE) and long-distance data cabling. While CCA is cheaper, its aluminum core makes it more brittle, more prone to failure, and incapable of meeting industry standards for Ethernet and PoE, making solid copper the preferred, higher-quality choice."
now eat shit, I don't even know why you want to argue about such an obvious shit
I'm starting to think you are unironically a jew

>>2945591
>joo!
I was with you up until you wrote this. Now I've returned to being against all of you. Hmph!
*adjusts yarmulke angle*
Stop golem.

jews
aluminium inside will fall apart after 20..50 years causing higher resistance and very much house fires. >2.5mm^2 solid core copper is a pain in the ass to install, but at least it will not break apart like a copper wire after just 3 turns. also copper oxide is green, which can be easy to inspect, while aluminum oxide is white, which is harder to see on a gray metallic surface.

What is your opinion on aluminum feeder lines into the main load center and sub panels. Are they as troublesome as the aluminum branch circuit wires?

>>2945544 (OP)
It's basically reverse coin shaving, so who do you think invented it?

Jews mad over the penny meme

They are fine because Johnny Homeowner doesn't touch them.

>>2945544 (OP)
tell me when you found that bastard

>>2945544 (OP)
CCA > Pure alu.
CCA works with copper terminals and crimps.
Pure alu corrodes to shit in contact with copper.

There are a bunch of AD's on aircraft that unfortunately had this CCA shit installed when they were built. It either develops cracks and you lose your electrical system (usually the starter is the first to go) or it decides to catch fire where it cracks.

we both know the answer anon
great scam on the cu-au ratio
