Anotation

IEC 62420:2008 specifies the electrical and mechanical characteristics of concentric lay stranded overhead electrical conductors, containing one or more self-supporting alumimium or aluminium alloy layer(s) made of combination of any of the following metal wires: - Hand drawn aluminium as per IEC 60889, designated A1; - aluminium alloy type A or B as per IEC 60104, designated A2 or A3; - thermal resistant aluminium alloy as per IEC 62004, designated AT1, AT2, AT3, or AT4; - regular strength steel as per IEC 60888, designated S1A or S1B; - high strength steel as per IEC 60888, designated S2A or S2B; - extra-high strength steel as per IEC 60888, designated S3A; - aluminium-clad steel as per IEC 61232, designated 20SA, 27SA, 30SA or 40SA. La CEI 62420:2008 specifie les caracteristiques electriques et mecaniques des conducteurs pour lignes electriques aeriennes, cables en couches concentriques comprenant une ou plusieurs couches daluminium ou dalliage daluminium autoporteuses, constituees de combinaisons de lun des cables metalliques suivants: - aluminium ecroui dur selon la CEI 60889, designe A1; - alliage daluminium de type A ou B selon la CEI 60104, designe A2 ou A3; - type dalliage daluminium resistant a la chaleur selon la CEI 62004, designe AT1, AT2, AT3 ou AT4; - acier a resistance normale selon la CEI 60888, designe S1A ou S1B; - acier a haute resistance selon la CEI 60888, designe S2A ou S2B; - acier a tres haute resistance selon la CEI 60888, designe S3A; - acier revetu daluminium selon la CEI 61232, designe 20SA, 27SA, 30SA ou 40SA.
