I wondered if it looked a bit like black steel tubing with singles in. The plastic looks rather like a poor attempt at waterproofing. It just all looks rather straight for cable.
I have never seen cable with so much plastic filler so it does make me wonder. The braiding at the other end does look unusual, a bit like SY flex cable. but that usually has a clear jacket.
Texas, if you want some SWA, PM me and I can send you some.
