Scope

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.
