Standard Specification for Compact Round Stranded Copper Conductors Using Single Input Wire Construction
This specification deals with bare compact round stranded conductors made from uncoated copper wires of a single input wire diameter for general use in covered or insulated electrical wires or cables. Welds and brazes may be made in rods or in wires. The length and direction of lay are specified. The construction requirements of compact round single input wire-stranded copper conductors are also detailed. The mass and electrical resistance of the conductor shall be determined. Tests for the physical and electrical properties of wires shall be made.
1.1 This specification covers bare compact round stranded conductors made from uncoated copper wires of a single input wire (SIW) diameter for general use in covered or insulated electrical wires or cables. These conductors shall be constructed with one or more layers of helically laid compacted wires (Explanatory Note 1, Note 2, and Note 3).
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.2.1 For density, resistivity and temperature, the values stated in SI units are to be regarded as standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
