Product Description:

Appendix: Cable Properties
1. The cable is characterized by anti-acid and anti-alkali, anti-oil, and anti-aging, etc; Shielded type is anti-interference.
2. Low smoke and low halogen wire and cable has low fuming amount, releasing little hydrogen chloride, so on fire, it cause little corrosion, danger and damage to equipment, people and environment.
3. Cross-linked polyethylene insulating cable has large current capacity; and it is light and handy in structure. It is not restricted by drop. Cable short time over loading working temperature should not exceed 130
; Total short circuit temperature not exceed 250; Lasting for no more than five seconds.
4. fire-resistant cable can work for over 90 minutes under 750
-900; the fireproof properties test accords with GB12666.6 standards.

Q:A power cable has length 2000m. The cable is made of twelve parallel strands of copper wire each of diameter is 0.51mm, what is the resistance of cable?
Resistance (R) of a wire is given by: R = ρ.L / A where (ρ) is the resistivity of the wire in Ω.m ; (A) is the cross sectional area of the cable in m² ; (L) is the length of the wire in metres. Radius (r) of one strand = (0.51 / 2) = 0.255 mm = 0.000255 m Cross sectional area of one strand = πr² = (π * 0.000255²) = 2.0428 x 10^-7 m² Total cross section of cable = (12 * 2.0428 x 10^-7 m²) = 2.45 x 10^-6 m² R = (1.7 x 10^-8 * 2000 / 2.45 x 10^-6) = 13.87 = 14 Ω to 2 significant figures.
Q:Flat power cables?
Hi Allotted, The best thing to do is cut into the wall and run the cables down the inside. By the time you have power, DVD/VCR, cable connection and a dozen other things you have a huge bundle of cables. Cut a opening behind the TV and run the wires down the inside to the floor. Make an opening to bring them out there. I did mine like that and while it took some effort the results were a great looking installation. Norm
Q:What accessories/cables should I buy for this apple computer?
Power cable, USB keyboard, USB mouse. That's it. Find a power cable (any old computer power cable will work) and see if it even powers on and does anything first. Crack it open. Set it on its face, then undo the three screws across the bottom. They do NOT come out. They only loosen up until you can't turn them anymore. The back pops off. Look for any swollen or leaking capacitors. If you find any, then it's junk. If you don't, then see if there's any RAM in it. If not, toss some PC3200 DDR RAM in there and see if you get anything.
Q:where do i plug in the six pin power cable?
In a place where there are 6 holes!! lol
Q:whats better, a external hard drive with a power cable or not?
As Both ESATA and USB 2.0. The bomb. My enclosures are all pretty generic. Good luck.
Q:I have a 42 inch Toshiba REGZA I just got it and my dog chewed on the power cable where can I get another one?
Try Radio Shack or if it has a 3 prong socket any computer power cable will work.
Q:What does an OEM hard drive require to use? power cables, controller cards, etc.?
just the data and power cable and if your mobo doesnt support that type of drive (like if it only has ide and you want sata) then you will need a controller card
Q:is it safe to solder a power cable?
safe if you do it correctly but not recommended as there is too much chance for problems that could cause a fire later, if the joint came apart or the tape dried up. .
Q:How should connectors for storage device cables and connectors for power supply be described?
Storage cables have basically 3 types: IDE, SATA and SCSI, and are referred to by those names. Power connectors are sometimes called molex connectors after the company that first made them, or just power connectors and their applicable voltage they supply.
Q:Cable zc_y v22 what does it mean
If you put seven 1.0 square conductor twisted together, as a power can of course. But you twisted the copper wire, how to solve the insulation? In addition, the manual twist, then there is the problem of density, can not be a bit twisted copper wire twisted round? And if you put the seven core core is not peeling, directly twisted together, then, when the wire when the core heat how you solve. So, do not use this line to do home improvement. But if you want to use this line to do the lamp line or can.
