Braided Copper Wire
I have some copper wire that looks like yarn, about 16ga, that is
made up of maybe 100 or more hair-thin copper wires twisted
Braided Wire is also Electrolytic Copper Wire which is drawn and
annealed, but main thing is this that all wires in the same are
Braided together which is done in all the material like Bare Copper,
Tin Plated, Silver Plated which are then used in Shielded Cable,
Earthing Wire, D.Solder Wire, CRT Earthing Wire Assembly, Control
Panel, Switch Gear Box, MCV Etc.
is the description that came to mind when the query was posed.
