Power Cables Info: Amperage, Current, Wattage & More

[drag]

Greetings !

I was searching for this on the web for a couple of
days and found practicly nothing. This is highly unfortunate
because it means that not only did I not get the
info I wanted but I'm also lousy when it comes to such searches
(and I was actually of the opposite opinion prior to that ).
Please, help !

I need data on high voltage power cables - amperage per
cross section area, current, wattage, voltage, tensile
strenght, dimensions, materials - everything ! Also, info
on more effective than ussual power cables rarely used (due
to costs and so on, not interested in super-conductors unless
you can find some that'll work up to room temprature ).

Thanks !

Live long and prosper.

Thanks sheldon !

Unfortunetly, I still couldn't find cables with the full data
I need. Anybody ?

I would get some names and contact the manufacturers directly. Usually large companies will have at least one scientist or engineer that will tell you as much as you can stand.

What exactly are you trying to accomplish?

Well, the primary things I want are - low mass, high voltage
(use for a large distance) and a few MWs going through.

Thanks !

I am sorry, but that simply isn't enough info for me to help. You haven't specified a distance you are going, what you are intending on powering, What voltage levels are you trying to reach, all this information would be helpful so anybody on here could help you. Is it a secret invention?

Well, I wasn't asking for THE cable. Just some general
info on the appropriate range of possibilities.

Let's say between a mile and up to a few hundred miles.

Doesn't matter with a transformator.

Appropriate for low power loss at such distance ranges.

Thank you.

Not invention, but I was thinking about some interesting
ways to provide power to various distant locations across
various "unfriendly" territories.

Live long and prosper.

You explained that you are going to transform back down from any voltage level so it doesn't matter what you’re powering. All you really need to know is the higher the voltage the smaller the current and since the current is smaller the conductor can be smaller, but the insulation level must be increased. You may have problems keeping the wires from breaking if you go to thin unless you add extra support in which case you might as well utilize traditional power lines and transformers as they would be cheaper and available. You want to go through unfriendly territories; this could mean all kinds of things. I will assume the worse, a war zone. In that case you would have to transmit it without wires to prevent the enemy from cutting your cables. You could laser it or use concentrated rf or use resonant tesla coil transmitter and receiver and transmit it through the ground or air, or construct mini power plants at each location, or mobile power plants. Or if your looking to just get power there, you could should a rocket at your target area with a tether wire attached to it. Don’t worry about insulation and safety cause you would just use such a high voltage the current would be too low to hurt anything and just transform it down as long as you can. The wire could just lie on the ground that would relieve it from the stress of stretching it in the air. It would be hard to spot because of it being thin. I personally don’t think you need to worry so much about the actual specs of the wire, most of the sizes are determined from safety of use. A conductor can actually transmit quite a lot of power before melt down and the codes go well beyond those levels just for safety reasons. If you’re in some unsafe areas in the first place why worry about that? So figure out what size wire you want and just increase voltage accordingly to decrease current, get matching xformers and tadaa.

Perhaps he is talking about rough terrain, mountains and such?

Just use 8 gauge speaker wire and duct tape, you can do anything with it.

O.K. guys, I was still kin'na hoping to find cable data,
but you've sure helped me. Thanks !
