Copper Clad Aluminum Wire

CCA has its own features of density equality of copper layer, high compactness and fine en-longing capacity,which carries many characteristics of good conductivity, high strength and strong brazing ability of copper and low density and easily to process of aluminum. This bimetal compound lead can be used in the coaxial cable conductor with high signal transmitted features, and become the widely-used lead in CATV and other high frequency appliances. CCA is also the best choice materials for the coaxial cable conductor and cable wire of many electric equipment.

CCA Features:
1. DR Resistivity: CCA resistivity is 1.5 times that that of pure copper wire. CCA weight is about 1.2 times than pure copper wire on the same resistivity. According to the skin effect, its resistivity is the same with pure copper wire while above the 5MHZ. So CCA electric capacity is as well as pure copper wire while is used in digital cable and signal cable with high frequency.
2. Compared with pure copper wire, CCA has no value for larceners, because it become impossible to depart the pure copper cladding layer from aluminum heart yarn, so it has special function of anti-burglary.
3. With light weight, CAA is easy to transmit and fixed, on the other hand it can reduce labor cost.
4. CCA has better plasticity than copper wire, and it will never produce insulated oxide like aluminum, so it is easy to tackle with better conductivity.

5.Our products takes the international leading craftwork of cladding welding & drawing method, so even in the strict wringing test, it will never take off, craze or flake, having no harm to human health and environment.

CCA (copper clad aluminum) wire is now widely used in lots of low voltage cable industries instead of copper wire, becuase of its high performance vesus price ratio. It combines the excellent conductivity of copper with the light weight of aluminum

Q: Suppose load is 100KW, length 50m, how to calculate cable size. If we know current Is any easy mathod to calculate cable size.: There are two issues to consider, cable heating and voltage drop. Of the two, voltage drop is by far the easiest. You need to determine what the allowable voltage drop in you cable is. The voltage drop is just I x R where I is the current and R is teh round trip cable resistance. The specification of 100 kW isn't enough. If its a high tension 100 kV line, the current is only 1 amp and a run of 16 AWG wire would deliver about 99,999 volts out of the original 100,000 volts to your load. If its a 100 volt system then a 4 AWG wire would only deliver only 20 volts to the load. The formula for wire resistance (in AWG) is that 10 AWG has 0.001 ohm/ft. Each increase of 1 in the gauge increases resistance by the cube root of 2 (about 25%). You calculate by picking what voltage drop you can live with, for the known current figure the resistance, knowing the length figure the resistance per foot, and then pick the AWG using the above. The second concern is wire heating. Although you could do the heat transfer calculations, instead look up the allowable ampacity for any wire in an electrical engineers or NEC handbook.

Q: The power is a 24 pin and does not have a green wire. It has a grey, 6 red, 3 blue, a yellow , an Orange, a purple, a dark blue, 8 black, and a brown: MATERIALS 1.) power supply 2.) power cable 3.)paper clip Step 1 Plug in the Power Cable to the wall, and then into the back of the Power Supply. Make sure the Power Supply is flipped to 1 and not 0. I like to remember 1 is for power because 1 looks like I, and I have ADHD. So I always haves me some powers. 0 is like O which is like my OH face. Then I am drained of power. Step 2 Take the paper clip and bend it into a 'U' shape. We want the two ends of it to be next to each other, or relatively close. Step 3 Now we are in the final step. Locate the Green wire on your PSU. There should only be one Green wire, whether you have a 20 or 24 pin power cable. Alright, we found it. Now we get have to find a Black wire on your PSU as well. There are a few, but we should be fine. Finally, take the paper clip and insert one end into the Green wire and the other end into any Black wire. And there we have it. Your power supply is alive and kicking. Again, this is a good way to test fans for functionality, CD-ROMs, and Floppy Drives. Almost any component that will plug into this is fine. I would not advise for your hard drive in case of data loss, but if it's a questionable hard drive (why else would we test it?) then you I'm guessing you don't care if it has anything on it, or it's too old to matter.

Q: Can i leave my laptop on the whole day and just turn it off at night? It has a standby mode but i dont no if thats resourceful. Also it has sleep and hibernate. Will leaving the power cord in be bad?: most of the time, batteries will not be harmed by leaving them on charge. however the way most people use is shutting down the system turning off computer from start button. power cord left pluged in would not matter if system were shut down.

Q: At the end of every work day I shut it down in the normal way (through the Start Menu) and then every morning I return to it and it won't turn on no matter how many times I press the on button or if I hold it down.The only way I can get the computer to turn back on is to remove the power cable for 10 minutes and then put it back in and hold the on button for about 10 seconds. This is a bit of a pain but also quite worrying as the computer is new.I wonder if my computer is broken or if this is an intentional feature. If so how do I turn it off?It might help to know that even when I have shut it down there is an LED on the back that stays on. In fact it stays on for 5 minutes even if I take the power cable out!I have a Dell Vostro 260S PC. It runs Windows 7 64-bit and the processor is an Intel i3Please help techies.: This sounds like a bad shutdown. Are you sure it's shutting down and not hibernating or sleeping? As it's new, you should call Dell, but you can try this. Close all your programs and shut it down by holding the power button in until it's off (Just 5-6 seconds.) See if it starts up after that. Edit:What happens if you try shutting down with the On/Off switch?

Q: I am upgrading a two-year-old higher end HP tower to include a mirrored hard drive. I did a little vacuuming and inspection and plan to order the exact model drive which is in there now. I noticed that the SATA cables used include a simple plastic latching mechanism in the connector. I checked CDW and found quot;latchingcables made by Startech which I assume should work (but the latching part is made of stamped metal). My biggest question is the power connector. The factory installed molex-to-SATA adapter also has this latch mechanism (on the black hard drive side), but I cannot find a cable anywhere mentioning a latch on the power connector. Is this something specific to factory installation?Thanks.: No. Latching cables as you call them are available at retailers. Try Newegg...

Q: why power cables are to be earthed at both ends?: Its called the M.E.N. system. It stands for Multiple Earth Neutral. The neutral of an appliance acts as a return, held at a low potential by earthing at each house, using rods into the ground, transformers in the street with earths, and earth mats where required when soils are not conductive. When a fault occurs to earth the low earthing point causes the fuse / breaker to trip. GL

Q: I tried looking up the the model # and a couple of sites that would sell it but cant find any. Also the player is like 2 years old so hard to find anything about it.: What is the question here? Are you looking to buy a replacement power cable? One of the multi use ones would work fine, set it for 9 volts. The other important part is the current rating (amps or mA). What does the DVD player say it needs? Make sure the new power cord can supply at least that much. Voltage: try 9 first, if not work then try 10 or 11 or 12. No higher than 12. Current: the same number or higher than listed on the player.

Q: Which is the best way to prevent damage to the laptop / ac power jack when someone trips on the cable ?Dont ask me to buy a Mac since I already have one. This is for my new PC notebook.: I would suggest using the velcro tye's you can get at any electronic store. Try tying off at the leg of your table. You can also use gaffing tape to tape it down to your floor. Gaffers tape usually doesn't leave a residue and is easily removed. Again, you can get it at Home Depot int he electronics section. Oh yeah, and be careful. :o)

Q: So I have a ordinary pc with a 500gb seagate hardrive in...and I have another seagate hardrive I want to put in (also 500gb) but do I need the sata power cable since it is not the main hardrive or can I only insert the Data cable for the harddrive since I didn't get any cables with my hardrive do I need need both cables, the Data and power cables or can only use the data cable ?: You always need a power cable as well. The power cables are part of your computer's power supply unit and are never being shipped with harddrives.

Q: how do i run my power cable wire through the firewall, to my battery in my 1995 Monte carlo?please help?: Now djp answered this question correctly but after drilling the hole makes sure you put a grommet in the hole to prevent a short
