- Q: There have been severe storms in my country Kenya and power lines have fallen and caused a lot of injuries, some fatal to pedestrians, motorists and others.I am sure if power lines were covered with rubber sheathing or some other apopropriatde material, there would be less likelihood of electrocution, serious injury, fire or property damage. I am a lay person in these matters so I am talking from what I have seen.Thanks in advance.
- Let's see... First of all ONLY high voltage power cables do not have protective polymer insulation. Low voltage cables, like the ones that bring outlet tension to homes do have an insulation, usually made of PVC, rubber, silicone and such. The large, 10000Volts, up to and over 200000 volts and so on do not for several reasons: 1. It would be impractical to make. For usual materials, like PVC the thickness of the insulation would be extreme (I think as thick as several centimeters) as to protect from such high voltages. Such insulations would make the cables break under their own weight. 2. The cables heat up really good under the enormous currents and voltages so the insulation plastic would be close to melting point all the time. 3. PVC is quite senzitive to weather curing. It becomes brittle and cracks if left under weather condition for several years so the insulation would still serve to no good. Furthermore, regulations regarding aerial wiring state that they should avoid crossing populated areas, roads, etc. unless absolutely necessary. Also, wires fallen on ground should definitely not be messed with. Furthermore, if high voltage cables were insulated, this would only serve ready made combustion materials for fires in case of short circuits and damages. I guess this takes care of your question...
- Q: I looked on 3 of my friends plus mine and looked at the cord that comes from the big block power supply thing for the xbox 360 and every one of them looked differant. Why is that?
- Because each one is an individual Just thought you should know An individual its true They all are different and have different kittens(lol) Individual it TRUE!!!!! Lol this song is to the beat of- you are beautiful- christina aguilera
- Q: I dont get any power to my amp. If something is pinching the line could that make it not get any power? Or could there be something else wrong?
- i would also check ur ground wire.no power means 2 things power wire not secure or the ground is not connected right
- Q: If I buy a PS3 in the US and bring it back to France, if I buy the french power cable and exchange it with the US power cable, will the PS3 work? I have a transformer which I already use for my Wii so if the power cable doesnt work for the PS3, I can just use the transformer.
- Some PS3s have universal power supply. To know which one you have you need to open it. If you don't want to open it (and void the warranty) - use power converter. Note: for PS3 you'll need at least 400 Watt. As for power cable itself - depends on the socket on your power converter.
- Q: What does ZR-YJV 6mm2 * 3 cable mean? What does ZR-YJV6mm2 * 3 cable mean?
- The initial also said that car 3S brand stores, mainly refers to the front of the three S
- Q: Were can i buy a replacement power cable ?
- FOR WHAT??????????
- Q: And my other drive has the only analog audio cable on my motherboard hooked up to it, and i know i need to plug in one more cable, because windows wont start up the way i set it up and idk what needs to go into which port.
- Are your drives IDE, SCSI or SATA? If they are IDE, are the jumpers set correctly for master/slave or cable select?
- Q: I've been looking online for some but can't seem to find some sync cables to strap these amps together. Anyone know where I can find them?
- go okorder and you'll see you want..
- Q: So I use my laptop with power and only put in the battery when I take it around. So I sat my computer down and it abruptly just shut down. I powered it on and I set it down again and the same thing happened. The third time it went all the way to the desk top. I touched and moved around the power cable connected to it shut down. WTF
- sensitive power supply connection i guess
- Q: I have a Raidmax 730w power supply, and its modular. there is only one plug in for a 6 pin, and the cable has 2 different 6 pins on the same cable. Will this cable be able to run 2 different video cards running XFire? or will is also be able to run say a 6870 that requires 2 6 pin connectors?
- You should be able to feed two cards that each require 1 6/8 pin PCI-E power source... or 1 card that requires 2 6/8 pin PCI-E power source. A cable with 6 pin provides 75W power to the card. With the 75W available on the PCI-E x16 slot, that would be a 150W supply. 2 6 pins will up the available wattage to 225W. Cards that require a 6 pin and 8 pin are 300W cards. Your cable/PSU port is designed to provide any of those combinations of power to the videos card(s).
