Q:What is the safe carrying capacity of the power cable YJV22-10KV-3 * 400?

Depending on how much of the 24 switches that U ah, 1U, then up to 42 slightly, but still empty position good heat dissipation, 2U, then installed a 20 up to the bar.

Q:what is the difference in applications between single and multicore power cables?

Multi-core power cables are useful any time you're carrying a circuit in and out of an appliance at the same location. Usually that's just 2 plus an optional ground. For electronic devices with specialized power requirements, there may be several power lines in the cable carrying different voltages. Single-core power cables are especially useful in high amperage appliances, such as welding equipment, and in DC automotive wiring in which the chassis serves as the ground. Thick cables for high amperage are hard enough to manage and wire without being bundled into a multi-core monster. It also makes sense to use single core cables with a ground chassis so that you only have to run one wire, and just complete the circuit to ground at the point of use. Single-core power cables can also be useful in serial or parallel wired appliances, or power supplies, such as a string of lights, or an array of batteries.

Q:I recently bought a Logitech Rechargeable Speaker S315i, but i lost the power supply at a party. I was wondering if anyone know of a website where i could just order another cable (that fits and work) for the rechargeable speakers. 100-240v Power supply. Or do i have to buy a new speaker?

There is no direct benefit for the operation of the speakers by upgrading to a 750 watt power supply. The amplificatiion power is external. Only a small relatively small power signal is delivered by the computer

Q:high effency double shielded transmission power cable?

What is your question? Does such a cable exist? Probably but you'll have to be more specific. High efficiency = low loss or low resistance per foot? Double shielded = is the shielding (in dB) critical? Transmission = What frequency, 60 Hz, 1 MHz, 100 MHz, ? Power = Watts, KW, MW Is weight or cost important?

Q:i'm having a power cable coming from the feeder pillar going to utility box that serving a yacht, i'm having few cut off in that cable what is the most good idea to repair it without replacing the cable and what is the material that used in that ?

Have you got an anti surge socket to even out any voltage spike in line? I have and I've had several power cuts and my computer has never been affected. If not, then there is a possibility that you have blown the motherboard or the PSU. The reason this happens is your PSU drops the mains voltage from 240V to about 4.5V or less that your motherboard uses. Now when you get a power cut, when the switches in the power lines drop out, as the gap in the switch increases the voltage will jump as the current is trying to jump the gap. Thus for a few milliseconds the voltage in the mains can jump up to 20% which take it up to about 280V. Push that ratio all the way along and your motherboard voltage will jump to about 6V. Poof! Motherboard blown. Your only option is to put it into a workshop and find out exactly what damage you have done to it. You may be lucky as some manufacturers fit internal anti surge fuses.

Q:Also i want to add more power cables to power my hardrives WHAT SHOULD I BUY !!?

You buy internal SATA cables from a store like Micro Center. You can also buy adapters that plug into your hard drive power supply connectors and then your SATA drives. But you could also buy a new power supply that has multiple SATA power connectors

Q:i just got a junked up PS2 and i'm taking it apart to see what all is wrong with it and do a thorough cleaning of everything inside and i discovered that the problem is the power eject ribbon cable is tattered. is there anyway i can make a homemade style cable or repair the old one. i know there are like 5 to 10 bucks but im a major cheapa$$ so to say so any tips or tricks???

No, once that is broken you can not fix a ribbon cable but you might be able to get them cheaper on OKorder.

Q:Soooooo I don't know much about electronics, but... I'm pretty that my AC power cable for my new receiver was made wrong. You know how it supposed to have a positive and a negative pins? well they are both the same. I know that the wall outlet has the little whole and the bigger one. I've seen some AC power cables that only have the little flat pins so they fit on the wall outlet. My cable has two of the big flat pins... so I can't plug it in the outlet. What do I do? is there like a plug I could buy? I've been using google but I can't find anything...

If the equipment is under warranty, I might consider taking it back and complaining. If not, the hardware store is your recourse here. Good luck!

Q:if found the reistance then what are the acceptable limits such that replace the cable or repair the cable

See the document by Megger on how to determine if a cable is good and much more. This is a very good document that covers both static (insulation hipot testing) and TDR fault location methods.

Q:Every time i unplug the power cable from my laptop the wireless connection stops working and i can't seem to fix it by changing the wireless power options any ideas?

I am assuming that you are using windows, If you haven't done so already, right click on the battery on the right hand of your task bar and click on the power options. now, click on CHANGE PLAN SETTINGS Then click on CHANGE ADVANCED POWER SETTINGS a new window should pop up, look for wireless adaptor settings and select maximum performance, This could be your answer but then again I'm not sure what you have already attempted.
