Show Complete Document History
The following bibliographic material is provided to assist you with your purchasing decision:
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.
