AL3/ST3D
AL3/ST3D is a EN 50182 / FprEN 50540 (overhead conductors) cable designation: AL3 = AL2 to AL7: aluminium-magnesium-silicon alloy wires (EN 50183), the digit naming the alloy type (EN 50182:2001 1 b), 4.2); ST3D = STyz: zinc coated steel wires (EN 50189), y the steel grade (1 to 6), z the zinc coating class (A to E) (EN 50182:2001 1 c), 4.3); AL3/ST3D = AACSR: AL3 aluminium alloy wires (the envelope) round a core of ST3D zinc coated 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 4.3.
