This specification covers bare rope-lay-stranded conductors having concentric-stranded members made from round copper wires, either uncoated or coated with tin, lead, or lead-alloy for use as electrical conductors. Coated wires shall include only those wires with finished diameters and densities substantially equal to the respective diameters and densities of uncoated wires. The rope-lay-stranded copper conductors under this specification are classified either as Class G or Class H. Requirements for joint construction (by soldering, brazing, or welding), lay length, and strand construction are detailed. Tests for the electrical properties of wires composing conductors made from soft or annealed copper wire, bare or coated, shall be made before stranding, while tests for the physical properties (such as elongation) may be made upon the wires before stranding or upon wires removed from the completed stranded conductors, but need not be made upon both. Elongation tests to determine compliance shall not be made on the conductor as a unit. If a tinning, lead-coating, or lead-alloy-coating test is required, it shall be made on the wires prior to stranding. The method of calculating mass, cross-sections and electrical resistance, and the prescribed density of copper to be taken for calculations are given.

Scope

1.1 This specification covers bare rope-lay-stranded conductors having concentric-stranded members made from round copper wires, either uncoated or coated with tin, lead, or lead-alloy for use as electrical conductors (Explanatory Note 1 and Note 2).

1.2 Coated wires shall include only those wires with finished diameters and densities substantially equal to the respective diameters and densities of uncoated wires.

1.3 The values stated in inch-pound or SI units are to be regarded separately as standard. Each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. For conductor sizes designated by AWG or kcmil, the requirements in SI units have been numerically converted from corresponding values, stated or derived, in inch-pound units. For conductor sizes designated by SI units only, the requirements are stated or derived in SI units.

1.3.1 For density, resistivity, and temperature, the values stated in SI units are to be regarded as standard.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
