Product Application

Distribution power cable for static applications, mostly in ground, but also in water, within facilities, in cable canals, in concrete, in conditions requiring increased electric protection and protection against mechanical damages.
Used in electric power plants, transformer stations, industrial plants, metropolitan networks and other electric plants. Concentric conductor can be used as neutral protective or earth connection, and if there is a danger of damages caused by digging, it acts as protection against contact voltage, in case of rough insulation damage, Corrugated concentric conductor construction enables establishing of several cable connections without conductor cutting.
