Abstract
This specification applies to concentric-lay-stranded conductors made from round aluminum-zirconium alloy wires and an aluminum matrix composite (AMC) core wire(s) for use as overhead electrical conductors. It covers ordering information, requirements for wires, joints and lay, construction requirements, rated strength of conductor, density, mass per unit length and electrical resistance, and cross-sectional area. The standard also addresses workmanship, finish, and appearance, together with mechanical as well as electrical and dimensional tests, tests and retests, inspection, and packaging and package marking.
Scope
1.1 This specification covers concentric-lay-stranded conductors made from round aluminum-zirconium alloy wires and an aluminum matrix composite (AMC) core wire(s) for use as overhead electrical conductors (Explanatory Note 1 and Explanatory Note 2).
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
