For independent website / product page (English-oriented, suitable for international tender, Europe, America & EEU Ethiopia project) Standard：DIN VDE 0276-620 | HD 620 S1 | IEC 60502-2
Cable construction
NA2XS2Y: Single-core aluminium conductor, XLPE insulated, copper-wire-plus-copper-tape metallic screen, black HD-PE outer-sheath medium-voltage underground power cable (non-water-blocked version).
N = VDE German standard
A = Aluminium conductor
2X = XLPE cross-linked polyethylene insulation
S = Copper wires + counter-wound copper tape metallic screen
2Y = Black high-density polyethylene (HD-PE) outer sheath, UV-resistant, suitable for direct burial, outdoor, cable duct, indoor fixed installation, not for overhead use
