BS EN 50540:2010 Conductors for overhead lines. Aluminium conductors steel supported (ACSS)

BS EN 50540 is a European Standard which 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.

Outer/conductive layers:

Annealed Aluminium wire as per requirements of Clause 5.

Steel 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:
i Extra High Strength;
ii Ultra High Strength.
