ASTM B229-04

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

ABSTRACT
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. The conductors are classified under the following type designations: Type A, Type C, Type D, Type E, Type EK, Type F, Type G, Type J, Type K, Type N, Type P, and Type V. Welds and brazes may be made in copper rods or in copper wires prior to final drawing. Joints may not be made in the finished copper wires composing concentric-lay-stranded composite conductors containing a total of seven wires or less. In other conductors, welds and brazes may be made in the finished individual copper wires composing the conductor. Also, the joints or splices may be made in the finished individual copper-clad steel wires composing concentric-lay-stranded conductors, provided that such joints or splices have a protection equivalent to that of the wire itself and that they do not decrease the strength of the finished stranded conductor below the minimum breaking strength. The density, mass, and resistance of the wires shall be determined.
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 AType GType CType JType DType KType EType NType EKType PType FType 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.
