Q:what does it mean by 4 core cable, 35 mm. can it be used for DC and AC as well. can it be used for a 3 phase AC. what are its advantages and disadvantages? is one core means one phase? can we use 2 core cable for 3 phase AC? am really confused please explain.

A 4 core cable has 4 conductors in an overall sheath. The 35 mm indicates the area of each conductor's copper is 35 square mm. You can use the 4 core cable for 3-phase power (3 wires with a spare or ground). You cant use a 2-core cable for three phase service, unless you are using three 2-core cables with the 2 wires connected in parallel to provide one of the phases. It can be used for AC or DC. TexMav

Q:can we install power 480 VAC and control 120 VAC cables,,, each one in different conduit but in parallel and adjacent ?also for two control cables ,,,, can they installed in one conduit ?

Yes. That shouldn't be a problem. if it were data or extra low voltage dc then there could be some mutual induction issues. generally speaking. low and extra low voltage can be installed in the same conduit as long as the extra low voltage cables are insulated to the higher voltage present. ie use all cables rated at the highest voltage.

Q:I'm only asking this on here out of interest, this is not homework. I want to know how to calculate exact distances between to poles connected at the top by a cable. The length or height of the objects are not important to me, but if you must use an example please do so. So I want to know what formulas to use, what variables in those formulas mean, and how the slope of the cable will affect the distance. For example, if two poles have a distance between them of 0, and the cable extends 100, it would not mean that the drop of the cable (called a catenary?) would be 50, (it's misleading because you would think that since the distance between the two poles is 0, the cable would drop 50 and rise 50. But this is not taking into account the slope it has to take at the bottom of the catenary. It must lose some drop (perhaps to 48 or 49) in order to bend and rise back up...I want this out of my head, it's bugging me that I can't figure it out.

So you want the length along the cable? I honestly don't know how to compute the arc length of a catenary, but I'm sure that the power company knows how to do it because they need to know how much cable it will take to string up a whole line of poles. Your example doesn't work only because you impose a physically impossible constraint (zero distance between the poles - the poles have no thickness) and then try to impose physical reality (the cable can't bend instantaneously) on the problem. In the physically unrealizable problem, yes the cable does drop 50 ft because it is infinitely bendable. You're dealing with hyperbolic sines and cosines. Good luck

Q:holes to route the cable through anyone have pics or a website so i can figure it out

ye this is just a common problem on many cars/tucks not just ford. did a custom install on my jeep and had to cut small hole in front left insulation under dash. it came right out into open space under hood and made great place to run wire. if u cant see any holes/spaces to run it then ur gonna have to cut a hole ro have someone do a pro install for you. (ultimately its cheaper easier to diy - need power drill and a big enuf bit to fit wire thru. im sure u can figure it out, just go slow and be carful, mine worked quik and easy and sounds great. good luck w/ all that - hope i helped

Q:Only the ground cable is green, the two other cables are gray and I noticed that one is with stripes the other is not... The maker is Smart Choice. - there is more clue, one cable end is coded with a letter Z , other W , than G .... the G is probably the ground ( green ) . I need to know which one will connect to the black wire and which to the white one. Please help. Thank you

stripe to white black to plain wire green to chassis. The white is neutral black is line bare wire is green

Q:So I've been working on my computer aand looking to invest in a primary Hard Disk (instead of X2 250GB hard drives). I noticed the drive i have has Fantasy power outlets and newer models have SATA Power so I'm kind of confused on the Hard Drive i should get. I'm looking at hard drives 500GB-1TB

Fantasy power outlets don't sound standard. SATA is consistent on both PCs and Macintosh computers.

Q:Hello, i have a quick question, this card doesn't need PCI cables right?My power supply is 450 wattNVIDIA GTX 750 TI is the cardThank you

Check your exact model 750 Ti. Some don't require a 6-pin connector while some do.

Q:My laptop battery ran out because my power cable broke. I need to take out my files before I get it repaired. Is there a way I can charge my laptop? (HP Pavilion Entertainment)

Sounds like you just have to buy a new cable.

Q:I was looking at buying the MSI HD6850 cyclone OC/power edition but on the msi website it says it includes an external power cable. Am I missing something? Do I need more than the standard pci-e 6 pin connector from the PSU?

Some graphics cards require you to connect a power cable to the board. As it requires more power than it can get through the pci connection.

Q:Im looking for a sata cable that has one connector to the mother board and splits in two to connectors for to two HDD's (just like the old IDE cables )IM NOT LOOKING FOR THE POWER CABLE IM LOOKING FOR THE DATA CABLEdo you know were i can find one please give link were i can buy or tutorial were i can make my own

You okorder /
