Notes for Electrical Stranded Conductors as per IEC 61089

IEC 61089 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:
  • hard-drawn aluminium as per IEC 889 designated A1*
  • aluminium alloy type B as per IEC 104 designated A2*
  • aluminium alloy type A as per IEC 104 designated A3* (and when applicable to the following cores, as per IEC 888)
  • regular strength steel, designated S1A or S1B, where A and B are zinc coating classes, corresponding respectively to classes 1 and 2.
  • high strength steel, designated S2A or S2B.
  • extra high strength steel, designated S3A.
The conductors designations included in this standard are;
  • A1,A2,A3
  • A1/S1A, A1/S1B, A1/S2A, A1/S2B, A1/S3A, A2/S1A
  • A2/S1B, A1/S3A, A3/S1A
  • A3/S1B, A1/S3A, A1/A2, A1/A3

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

  • A1: 28,264 nm (corresponding to 61% IACS),
  • A2: 32,530 nm (corresponding to 53% IACS),
  • A3: 32,840 nm (corresponding to 52,5% IACS).
Testing shall be as per IEC 61089
