Hello Ebayers , up for buy it now is the most flexible multiconductor  cable i have ever seen  , if you buy some of this wire you will be amazed its a mystery about who made it and the exact details because we aquired this cable in a business closing down sale .  The spool it is on still had the plastic wrap and appeared to be new from factory , we think it is a medical grade cable as it was a laser medical business we bought it from.  Unfortunately there is no print on the cable itself and no label on the spool,  Description as follows : it is a 12 conductor s total and it is twisted pair (6) total pairs , the wires themselves are stranded (19 strands) each the black and white pair has its own braided shield,probably for video purposes,,overall diam of the cable is .20 inch , we think the outside jacket is a silicone white medical grade ,  each wire is believed to be 24 gauge measuring .6mm , there is also a non insulated stranded drain wire that makes contact with the braided OVERALL shield  (very amazing shield probably silver plated copper fine) there is 3 separate fiberglass flex inserted strips in the cable to keep it flexible , we have stripped the black wire to show the strands in the photos , we will show many photos , we hope that this is helpful , you are buying it now for 40ft sections , if you buy more than 40ft then you must buy at least 80ft and we will keep it continuous if you buy more than 2 sections then we will put it on a small spool no extra charge EXAMPLEs  you buy 3 sections (120ft total )  we put on spool cost would be 87 dollars , if you buy 240 ft total (6 sections ) we would keep it continuous length  $ 174 dollars and we put it on a spool, shipping very reasonable  please message us if you have questions
