Standard Specification for Rope-Lay-Stranded Copper Conductors Having Concentric-Stranded Members, for Electrical Conductors
 N B173

Annotation

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).

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

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.

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

Стандартная спецификация для медных проводников Rope-Lay-Stranded, концентрически скручивавших участники, для электрических проводников

Пустая веревка покрытий этой спецификации кладет скрученные проводники, концентрически скручивавшие участники, сделанные из круглых медных проводов, или непокрытых или покрытых оловом, выводом или свинцовым сплавом для использования в качестве электрических проводников (Пояснительное примечание 1 и Примечание 2).
