Some kind of aluminum wire or cable

I got this aluminum wire/cable it was at a house laying on a junk pile and I took it it had no sheathing just bare wire and at intervals there were these wing things I believe I took off 4 of them they were holding the wire down is my assumption and in the wing things there was a bolt on top and a stake like a vampire stake the stake screwed into the wing thing and then a bolt was screwed into the to of the wing thing.

The wire/cable is that considered extrusion? What about the stakes? I also have some smaller aluminum fiber wire like what you get in the copper form the stuff that pokes you when stripping with a utility knife lol.

Should i separate the aluminum wire from my copper wire the small stuff not the cable. the cable is braided i forget how many wires are braided together should i count them separately would that get a better idea on what it is if i had how many wires were in it? I believe the wing thing is some type of a wire clamp.
