This draft European Standard specifies the electrical and mechanical characteristics of ACSS conductors made of round or formed annealed aluminium wires and steel wires stranded in alternate directions, made of one or a combination of any of the following. 1.1Outer/conductive layers Annealed Aluminium wire as per requirements of Clause 5. 1.2Steel core a)Galvanized steel wire type ST6A according to EN 50189 and requirements of Clause 5; b)Zn95Al5 alloy coated steel wire with MM (mischmetal) as per EN 10244-2 and mechanical and mass of coating requirements as per Tables 2 and 3, in the following options: iExtra High Strength; iiUltra High Strength. NOTEMM elements are mandatory. Coatings without MM can be used, if agreed between Supplier and Purchaser. Tests without MM must show the same behaviour than the MM coatings. c)Aluminium-clad steel wire 20,3 % conductivity in the following options: -as per EN 61232 with class designation 20 SA; -aluminium-clad steel wire Extra High Strength with designation 20 EHSA as per Table 4. d)Aluminium-clad steel wire 14 % conductivity, Extra High Strength with designation 14 EHSA as per Table 5.
