\n (N)A2XS(F)2Y \u00b7 MEDIUM VOLTAGE POWER CABLE\n <\/div>\n\n

(N)A2XS(F)2Y Aluminium XLPE Medium Voltage Cable<\/h2>\n\n

\n (N)A2XS(F)2Y<\/strong> is a single-core medium-voltage\n power cable with a Class 2 circular compacted aluminium conductor,\n XLPE insulation, a copper wire and tape screen,\n longitudinal water-blocking layers and a black\n polyethylene (PE) outer sheath.\n <\/p>\n\n

\n Designed for fixed medium-voltage power distribution\n in underground networks, cable ducts, substations,\n power infrastructure and industrial installations.\n The swellable water-blocking tapes help limit\n longitudinal water propagation within the cable.\n <\/p>\n\n <\/div>\n\n\n \n
