Application:

76/132kV HV cables fall into the category of EHV XLPE insulated power cables. As a core product for132kV EHV power transmission networks, they replace 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, strong anti-environmental interference and small floor space, they are widely used in overhead-to-underground transformation of main power grids, cross-sea/river transmission and power grid construction in urban core areas.
