They are made of twisted aligned hard aluminium wires in species of EN AW-1350 or EN AW-1370. In view of the a relatively low strength-to-weight ratio, their use is strongly limited the maximum distance between the pillars. Therefore, these cables are the most often in urban areas where there are small distances between the supporting structures, and it is desirable to use high conductivity. The large advantage of these products is good corrosion resistance, and for this reason they are suspended in areas exposed to atmospheric agents, e.g. in coastal areas.
