Q:What is the max distance to pulling 220 or 380 KV cables without loss of power?
You are not providing enough information. 220 KV can provide power of TENS of miles on reasonably modest cable PROVIDING the current drain is not too high. Sorry but the idea of anyone playing around with almost .4 MV without the first idea about loading / cable diameter / insualtion requirements scares the crap out of me! Without the required information, all I can say is With the right cable at 380KV , hundreds of miles As an aside, if this is a temorary site, then the cost of buying generator will be WAY cheaper than the cost of the cable and transformers you wil require to turn 380Kv into 110 / 220V If a permenent fixture, then suggest for normal lighting and sockets (as in no industrial smelting plants!), then you would eed to be dropping the voltage either at the 380kv site OR at least some distance from the new fixture. Houses do not typically have .4 MV coming into the cellar. It might arc a few metres you see if the air is a little humid. Make things a bit dodgy. **UPDATE** Ok, thanks for clarifying the voltage. Now we also know power too -so at 220v, and about 12KW we are looking at VERY roughly 55 Amps. 25mm cable ought to be good for a couple of hundred metres or so. 16mm for upto 50 metres or so. If a LOT further than that, then either go with three phase/380 OR up the size of the cable. Problem is it can start getting pricey. The shorter the run, the lighter the cable can be - to a point - would NOT suggest going below 10mm under ANY circumstances. You will always get SOME voltage drop, but providing it is in the order of a couple of volts here and there, there is no appreciable waste / heat generation. Is this a fixed installation or a temporary one - if temporary and a fair distance away I would STILL be inclined to sugges a genset hire might work out cheaper than drums of suitable cable.
Q:What can be done to prevent the power cable on a Toshiba Satellite A215 laptop from burning up again?
those specs are good (no longer the full inspite of the truth that), inspite of the very incontrovertible truth that they are very imprecise, and in simple terms some aspects of the computing gadget you prefer to seem at. -AMD is an ok processor, yet you'll be conscious the same computing gadget with equivelent Intel processor will value quite extra because it truly is a better processor. as a lot as you, appears like AMD might want to paintings on your makes use of. -The demonstrate screen length is advantageous, yet for an extremely outstanding demonstrate screen i might want to ascertain it truly is were given wsxga(good) or wuxga(better) -in case you desire a swifter report-get entry to difficult force, attempt to get a 7200rpm difficult force, i'm guessing the only you listed is a 5400. (the added rpm is amazingly well worth the added $one hundred or so) My sister were given a satellite tv for pc about a three hundred and sixty 5 days in the past.... it truly is a good computing gadget, yet lately she's been having a situation with her computing gadget both shutting down accurate once you means it up (seconds after, earlier something a lot) or if it does start up the demonstrate screen remains off/black.... i have study up and placed this isn't the in simple terms Toshiba satellite tv for pc to do this. i imagine that Toshiba's Bios is the problem..... So understand that, and do a touch homework on problems with that express type
Q:Will a psp go /slim usb data and power cable work on a dead psp go?
No - bought one 2 hours ago, have been charging for 1 hour and it will not come on. Additionally, the orange light does not come on when charging. Maybe it works if it is not already dead, but I can 100% confirm it doesn't work with one already dead.
Q:Why is the power cable thick and the speaker wire thin?
This is because a lot more power is running through the power cable, to power the speakers.
Q:Shall i use directly Nikon S550 digi camera U.S. power cable in India?
India power outlets run 220v, not 120, so you are going to need a converter or a completely new power-supply.
Q:ASUS power supply issue. Power cable suddenly stopped charging.?
Seems to be a short circuit. This is a common problem with Laptops, including Asus Laptops. I've had Dells, Asus, Lenovo, and HP laptops and each laptop's power cord has broken at least once. Unfortunately, you're out of luck. You will need to buy a new power cord, which could run you anywhere from $15-60, depending on the vendor
Q:What does an AMD Radeon HD 7850 power adapter cable look like?
I have never seen one in my life! But have you researched it on google?
Q:Need help with power cable that came with my 8800 gs...?
It would be best if you specified which PSU you have. From past experiences, 1 connector to the PSU works fine.
Q:what causes cable fire?
a power surge can definitely cause a cable fire. but i believe insulation failure tops that, in buried cables in particular. and insulation failure is prompted more often with cables that come in direct contact with the earth, rather than those that may be run through piping, deterioting the insulation even faster. of course if the cable is damaged by digging, that could start a fire as well.
Q:computer build power supply help?
All the necessary wires with come with the PSU, modular or not. And nothing will happen. It will just feel like grease. Just go wash it off w soap
