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. FIG. 1 Standard Types of Composite Conductors
