Status: active
Page Count: 18
ICS Code (Power transmission and distribution lines): 29.240.20
scope:

This International Standard specifies the electrical and mechanical characteristics of round wire concentric lay overhead electrical stranded conductors made of combinations of any of the following metal wires:

a) hard-drawn aluminium as per IEC 889 designated A1*;

b) aluminium alloy type B as per IEC 104 designated A2*;

c) aluminium alloy type A as per IEC 104 designated A3* (and when applicable to the following cores, as per IEC 888);

d) regular strength steel, designated S1A or S1B, where A and B are zinc coating classes, corresponding respectively to classes 1 and 2;

e) high strength steel, designated S2A or S2B;

f) extra high strength steel, designated S3A.

The conductor designations included in this standard are:

A1, A2, A3,

A1/S1A, A1/S1B, A1/S2A, A1/S2B, A1/S3A, A2/S1A,

A2/S1B, A2/S3A, A3/S1A,

A3/S1B, A3/S3A, A1/A2, A1/A3.

* The resistivity of these metals is as follows (in increasing order):

A1: 28,264 nΩm (corresponding to 61% IACS),

A2: 32,530 nΩm (corresponding to 53% IACS),

A3: 32,840 nΩm (corresponding to 52,5% IACS).
