High and extra-high voltage cables AC/DC  
The Group manufactures high voltage cables since 1970. More specifically, from 1970 to 1996 the Group was manufacturing paper insulated high voltage cables. From 1996 onwards, the group manufactures high voltage cables with cross linked polyethylene (XLPE) insulation. In 2008 the Group acquired the capacity to manufacture extra-high voltage cables with cross linked polyethylene (XLPE) insulation with nominal voltage up to 500kV. 
The constant investments for the manufacture of high and extra-high voltage AC and DC cables, testing facilities, education and training of the technical staff are a testament that Cablel Hellenic Cables Group consistently delivers reliable cutting-edge products. 
High voltage cables are constructed with copper or aluminium conductors and super clean XLPE insulation. Extruded semiconductive layers are applied over and under the XLPE insulation simultaneously by a triple cross head. Over the extruded insulation screen a metallic screen is applied consisting of copper wires or a lead or aluminium sheath. PVC, HDPE and LSF are applied as outer sheath materials. DTS (Distributed temperature sensing) systems and DCR (Dynamic Cable Rating) systems can be provided. 
Our products are available according to various national and/or international standards, as well as according to the demands-specifications set by the client.
