Medium voltage NA2XSEBY cables for distribution networks. They are suitable for laying indoor, tunnel, cables trench and underground, it is able to bear external mechanical forces, but unable to bear heavy pulling force, it widely used in transformer stations, electric power plants and industrial plants.
