ABSTRACT:
The cable is made up of a series of pairs stranded alternately in one direction and the other. At the locations of the reversal of the stranding direction, the individual conductors are kept in the form of a web and welded together side by side. Between two thus bonded segments, the adjacent pairs are twisted in opposite directions. A ground wire is provided with lengths of sheathing which come to be placed in the bonded segments. These segments are marked by deposition of a radioactive substance or other indicator material detectable during a subsequent stage of manufacture and actuating marking. Once overall stranding and jacketing have taken place, or during those stages, the bonded segments are spotted owing to the indicator substance and are marked visibly.
