underground cable??

I found a roll (about 7lbs worth) of some sort of cable. I tried all kinds of google searches and can not find the exact type. its about an inch in diameter, has a black plastic outside with the next layer being a solid aluminum then 1/4 inch of white foam looking insulation, then a center wire that is about 1/8 inch and looks like aluminum center w/ a coating of what looks like copper.

i tried to take a pic but it just shows up as a white dot inside the black wrapping.

anybody know what it is and what it would go w/? i dont think it would be worth cleaning or is that center piece worth soemthing?



thanks

I would try stripping some of it to see how hard it would be to strip and also see if it has a copper core, even the aluminum has some value. Try to squeeze the end and see if any grease comes out, it might be what they call grease wire. You could also take a piece to your scrap yard and ask them if they would buy it.

thanks everyone.

its definitely aluminum on both the outside ring (just inside the plastic covering) and in the center peg. i dug a little more on the foam insulation and to me it does look like the peg has a covering of copper.. its thin though. no grease, just a lot of stickiness between the outside black covering and the outside ring of aluminum. the outside ring of aluminum is thick enough that wire clippers dont want to cut it unless i twist it to tear it ragged. i am pretty weak though. it only weighs 7lbs total so i think it would be to tough on my back to mess w/ it for a few bucks. if the center was solid copper i would be all over it.

the aluminum cover peg in the middle w/ the copper covering. what category would that go in if i did have it out clean?

What you have is coaxial hard line. I am a ham radio operator and have scraped it a few times. It is not worth striping as it is alot of work. I only got $0.03/lb i had 300lbs. You might be better off trying to sell it as coax hardline. New it cost over $5.00/ft.
