July 15, 2013  – Global cable player Nexans says its newest product—Energex Extra—is made possible through the conversion of its medium-voltage production to employ Dow Endurance HFDC-4202 tree-retardant cross-linked polyethylene (TR-XLPE) insulation. The company explains the advantages of the new cable include: improved resistance to water tree growth; higher retained dielectric strength after ICEA 360-day Accelerated Water Treeing Test (AWTT); and reduced cost of ownership through longer cable life. Nexans says it has received certification to CSA C68.5 (primary shielded and concentric neutral cable for distribution utilities), and is eligible to apply the CSA mark on products manufactured with this insulation. The company adds Energex Extra made with the HFDC-4202 insulation promises superb extrusion processing characteristics and enhanced strippability for easier of field accessory installation.
