    Abstract

    This specification covers bare compact round concentric-lay-stranded conductors made from uncoated round copper wires for general use for electrical purposes. Welds and brazes shall be made in rods and wires prior to final drawing. The conductors shall conform to the required construction values of nominal cross-sectional area, diameter, mass per unit length and dc electrical resistance. Tests for the physical and electrical properties of wires composing the conductors shall be made before stranding.

    This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

    1. Scope

    1.1 This specification covers bare compact round concentric-lay-stranded conductors made from uncoated round copper wires for general use for electrical purposes. These conductors shall be constructed with a central core surrounded by one or more layers of helically laid compacted wires (Explanatory Note 1 and Note 2).

    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.
