1 Scope and Normative References
1.1 Scope
This Standard is applicable to aluminium-magnesium-silicon alloy wires of two types having different mechanical and electrical properties for the manufacture of stranded conductors for overhead power transmission purposes. It specifies the mechanical and electrical properties of the above wires in the diameter range 1.50 mm-4.80 mm.
The two types are designated as Type LHA1 and Type LHA2 .
Expressive method of product refers to Appendix A.
