Our 38/66kV HV power cables represent a premium solution for demanding electrical transmission applications. These cables fall into the category of EHV XLPE insulated power cables and serve as a core product for 66KV EHV power transmission networks, effectively replacing overhead lines of the same voltage class for underground/tunnel laying in urban power grids, industrial parks and cross-regional transmission projects. Featuring large transmission capacity, excellent insulation properties, strong resistance to environmental interference and minimal space requirements, they are widely deployed in overhead-to-underground transformation of main power grids, cross-sea/river transmission projects and power grid construction in urban core areas.
