AL2/27SA
AL2/27SA is a EN 50182 / FprEN 50540 (overhead conductors) cable designation: AL2 = AL2 to AL7: aluminium-magnesium-silicon alloy wires (EN 50183), the digit naming the alloy type (EN 50182:2001 1 b), 4.2); 27SA = yzSA: aluminium-clad steel wires (EN 61232), z the cladding class (20, 27, 30 or 40), y the steel grade A or B (class 20SA only) (EN 50182:2001 1 d), 4.2); AL2/27SA = AL2 aluminium alloy wires (the envelope) round a core of 27SA aluminium-clad steel wires. Bare overhead line conductor: no insulation and no rated voltage; Annex F lists the sizes in frequent use country by country (the /overhead-conductors page). EN 50182:2001 4.4.
