I'm sorry you've been somewhat ignored but I think I happened to stumble across what you may be looking for just now:
They're "Power Line 3/4/5 Wire" from author ID #60238, which belongs to American Connections (aka Moneywrench Works) if I'm not mistaken. I don't use them because the wires fade out due to anti aliasing or something. Hope this helps.
