scope:

[Replace this clause with the following]

This 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) aluminum wires: (i) hard-drawn aluminum in accordance with CAN/CSA-C60889, designated A1;

(ii) aluminum alloy AA6101-T81 in accordance with CAN/CSA-C60104, designated A2; and

(iii) aluminum alloy AA6101-T83 in accordance with CAN/CSA-C60104, designated A4;

(b) zinc-coated steel wires in accordance with CAN/CSA-C60888:

(i) regular strength steel, designated S1A or S1B, where A and B are zinc coating classes;

(ii) high strength steel, designated S2A or S2B; and

(iii) extra high strength steel, designated S3A; and

(c) aluminum-clad steel wires in accordance with CAN/CSA-C61232 using Class 20, designated 20SA Type A, corresponding to a conductivity of 20.3% IACS.

The conductor designations covered by this Standard include but are not limited to

(a) A1, A2, A4;

(b) A1/S1A, A1/S1B, A1/S2A, A1/S2B, A1/S3A;

(c) A2/S1A, A2/S1B, A2/S3A;

(d) A1/20SA; and

(e) A1/A2, A1/A4.
