ASTM B229-02
(Specification)Standard Specification for Concentric-Lay-Stranded Copper and Copper-Clad Steel Composite Conductors
Standard Specification for Concentric-Lay-Stranded Copper and Copper-Clad Steel Composite Conductors
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.
