Products Application

Medium voltage power cable for static application in ground, within and outside facilities, outdoor, in cable canals, in water, in conditions where cables are not exposed to heavier mechanical stress and tensile strain. Due to its very low factor of dielectric loss, which remains constant over its entire operating lifetime, and owing to excellent insulation property of XLPE-material, firmly longitudinally spliced with conductor screen and insulation screen of semi-conductive material (extruded in one process), the cable has a high operating reliability. Used in transformer stations, electric power plants and industrial plants.
