Copper Clad Aluminum is an electrical conductor which has an outer sleeve of copper metallurgically

bonded to a solid aluminum core. The combination of these two metals make

it uniquely suited to many electrical applications

Standard:

SJ/T 11223-2000

ASTM B 566-93

Feature:

Compared to copper conductors:

Higher Flexibility due to lower elastic modulus

63% material weight reduction due to lower specific gravity of CCA over regular copper

Compared to aluminum conductors:

Better corrosion resistance than aluminum due to copper layer

Lower resistance due to high electric conductivity of copper

Better Solderability

Higher strength than aluminum

Application:

In high frequency signal transmission field, it is applied to:

l Standard Material of Conductor in CATV Coaxial Cable;

l 50 Ohm Radio Frequency Aerial;

l Leaky Cable;

l Soft Coaxial Radio Frequency Cable;

l Data Cable

In power transmission field, it can be applied to:

l Stranded wire;

l Power Cable;

l Control Cable;

l automotive cable;

l Building distribution wire;

l Busbar;

l Radio Frequency shielding;

In special electromagnetic wire, it can be applied to:

l Coils in motor and fans, mahjong machine, Loudspeakers

l Voice coils (e.g. in Headphone, Headset, ...)

l Windings

Manufacture Scope：

0.12MM~5.50MM

Q: I have a universal 02 sensor 4 wire (black, black, white and blue) the stock is white black and grey how do I wire it? thanks :): Keep in mind the sensor has a signal wire, a ground wire and a heater wire (or wires). Good luck!

Q: Car audio wiring diagram: If you cannot get a wiring diagram for your stereo or car. It's still pretty simple to install a stereo. You basically just gotta color code all the wires. Red sometimes orange is power wire, black is ground, blue is remote the rest are speaker wires. Look for wires that are identical such as light blue light blue with a white stripe, gray dark gray with a white stripe etc.....

Q: Found some electrical wiring resonably priced on craigslist but it says -----8 gauge (AWG), 3 wire, direct burry electrical cableDOES THAT MEAN ITS 3/0 WIRE? Because I need 3/0 wire direct burriedI am looking to buy some extra 3/0 wire and found some on craigslist for a reasonable price..: 3/0 is the gauge of the wire you are looking for. In this case, 3/0 means three zeros, or 000. Smaller numbers for the gauge mean larger wire. After the gauge reaches 0, additional zeros are added to indicate even larger sizes. 2/0 (or 00) is larger than 0, 3/0 is larger than 2/0, etc, so the 8 gauge wire you found is considerably smaller than the 3/0 (or 000) wire you need. Don't confuse this with a designation similar to 8/3. In this case, the 8 would be the gauge and the 3 is the number of insulated conductors in the cable.

Q: i need thin insulated wire like this.: it is called enameled magnet wire. try an electronics supply house or a motor and transformer electrical supply house. you can also purchase it online. you could also just take apart an old electric fan or door bell and unwind the magnetic wire. ~the other answerers don't understand wire, enameled magnet wire has a fine enamel insulation that needs to be sanded off in order to make a connection, as the enamel electrically insulates it to prevent an obvious short, but allows the inductive fields to easily pass through. it is used in all motors and most xfmr's.

Q: I like bending paperclips to make things, does anyone know where you could buy spools of the wire paperclips are made out of.(any type of wire that is the same size and material will work): For the best answers, search on this site https://shorturl.im/axqI3 No, I am afraid you can't ... you need a special alloy, not paper clips, which are mild steel.

Q: I am trying to test a engine coolant temperature sensor (ECT), and in one of the tests it states quot;connect the terminals of the electrical connector with a jumper wirequot;. Where can I find a jumper wire? Does it has to be an specific gauge or any jumper wire? please helpd: Jumper wire is just any piece of wire that allows you to connect two other wires/terminals whatever. You could probably even use a paperclip if it will fit, just have to be careful when jumpering that you don't let the bare material short to ground.

Q: Which are more secure, wired or wireless networks? Explain.: Leaving aside ways to attack a network that wired and wireless networks are equally vulnerable to: Wired networks can be protected with physical security (i.e. people generally have to break into a building to get access to a wireless network). Wireless networks can only be protected with encryption (although a properly configured one will have all the traffic encrypted, whereas that isn't the case with a typical wired network). So, generally speaking, wired networks are more secure.

Q: Okay, magnet wire is coated with some red fancy insulation. Is that just an enamel?If so, enamel coated copper wire magnet wire would be the same thing.I want to build a loudspeaker. This what I need?Are the coils used in loudspeakers the same ones used in inductor coils?One interesting question,When Faraday was experimenting with the effects of magnetism on electricity, how in the hell did he figure out the magnetic field increased with the number of turns of copper in his coils!I'm only assuming Faraday didn't have insulated copper wires.Lmao, if they aren't insulated, how in the heck is he suppose to know how much the field is increased. The Coil would just become a big conductor lol: Today we always use magnet wire from inductors, transformers and speaker, but Faraday didn't have any so he just used insulated wire. He was smarter the you and me, so if we know you need insulated wire, so did he.

Q: I NEED TO CHECK IF A WIRE IS GOOD ON A FITNESS MACHINE. HOW DO I KNOW IF ITS GOOD? WHAT SHOULD THE OHMS BE?: Wire Ohms

Q: I bought this ceiling lamp, and there are 4 wires coming out of it. One white and one black (positive and negative), a bare copper wire for grounding, but there's also a yellow striped green wire. I was wondering what's the latter one for ?In my ceiling I have the black, white and bare copper wires.I'm Canadian by the way: Bare and Grn Yel. are both grounds . Just connect one or the other to the 'bare' in the box.
