2XSE2Y / N2XSE2Y A2XSE2Y / NA2XSE2Y

Uo/U - 6/10 kV, 12/20 kV, 18/30kV IEC 60502-2 / DIN VDE 0276-620
The three-core cables with insulation of cross-linked polyethylene (XLPE) are designed for transfer and distribution of electrical power with nominal voltage Uo/U 6/10; 12/20; 18/30 kV and frequency 50 Hz in urban and district electrical networks and for electrical supply of transformer's substations, small and medium industrial plants.
 
They are suitable for use in distribution installations, electric power stations and industrial systems. 
The cables are for fixed assembly in lines with unlimited difference levels, indoor installations, in cable ducts, conduits and shafts, over shelves and grills directly underground in ditch and outdoor shelter.
