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 inner and external screen of semi-conductive material (extruded in one process), the cable has a high operating reliability.
Used in transformer stations, switching blocks, in electric power plants and industrial plants.
To avoid the effects of external impact, the adhering semi-conductive layer extruded between conductor and insulation, along with concentric copper conductor, secures restriction of electric field and resistance to partial discharges.
