Usually when cable is stolen the insulation, which could be used to identify the
owner, is burnt off the cable just leaving the copper conductor. In contrast to
more complex and expensive tagging techniques such as those using rare earth
elements, Nexans’ CORE-TAG® solution involves installing a coded fire-resistant
copper tape that is intertwined in the conductor.The dot-matrix markings
on the coded tape – typically identifying the owner (RFF in this case) – make it
easy to trace the origins of the stolen copper when it is brought to a scrap
dealer, even after the insulation has been burnt off.
