Medium voltage NA2XSERY cables for distribution networks. They are suitable for laying indoor, tunnel, cable trench, shaft or buried laying. The cable can withstand mechanical external forces and a certain tensile force, it widely used in transformer stations, electric power plants and industrial plants.
