64/110KV HV POWER CABLE

Application

Our 64/110kV HV power cables represent a premium solution for extra-high voltage power transmission requirements. These cables fall into the category of EHV XLPE insulated power cables and serve as a core product for 110kV 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 performance, strong anti-environmental interference capabilities and minimal floor space requirements, they are widely deployed in overhead-to-underground transformation of main power grids, cross-sea/river transmission applications, and power grid construction in urban core areas.
