  • anti-theft or anti-vandalism cables only have a core made up of copper strands and when you want to prevent theft, most of the time a thin steel bar is placed on them, which degrades the physical and mechanical qualities. of the cable, not being compatible for use in the overhead contact line. Due to its physical and electrical characteristics.
  • Copper cables for overhead laying are a widely used system.

  • the same fastening elements can be used, as the cable (1) of the invention is slightly larger in diameter (2.4 mm larger diameter).
  • Another advantage is that at first glance after installing the cable (1), it is not possible to differentiate it from the common copper cable.
  • the advantage is that from a practical point of view in the same installation catenary can coexist with and without this technology, this will create a homogeneous installation, which will help not to distinguish the sectors where there is still copper cable.
