Standart: IEC 60 502-2

Description: Cu / Al conductors • XLPE insulation • Cu screen • Armour st. tapes • PVC sheath flame retardant


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 and frequency 50 Hz in urban and district electrical networks and for electrical supply of transformer’s substations, small and medium industrial plants. The cables are manufactured with sheaths of flame retardant materials. 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.
