ASTM B229 : 04

Standard Specification for Concentric-Lay-Stranded Copper and Copper-Clad Steel Composite Conductors

Standard Details

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.
