1.1 This specification covers concentric-lay-stranded conductors made from uncoated hard-drawn round copper wires in combination with hard-drawn round copper-clad steel wires for general use as overhead electrical conductors.
1.2 For the purpose of this specification, conductors are classified under the following type designations (see Fig. 1):
| Type A | Type G |
| Type C | Type J |
| Type D | Type K |
| Type E | Type N |
| Type EK | Type P |
| Type F | Type V |

1.3 The SI values for density are regarded as the standard. For all other properties the inch-pound values are to be regarded as standard and the SI units may be approximate.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
