Description

Abstract

This specification covers concentric-lay-stranded conductors made from round aluminum 1350-H19 (extra hard) aluminum wires and round aluminum-clad steel core wires for use as overhead electrical conductors. For the purpose of this specification, conductors are classified as Class AA and Class A. The concentric-lay-stranded aluminum conductors, aluminum-clad steel reinforced (ACSR/AW) shall conform to the conductor size, number of wires, nominal diameter, rated strength, and mass per unit length. Before stranding, the aluminum and aluminum-clad steel core wires used shall meet all specfified requirements. The number and diameter of aluminum and steel wires and the areas of cross section of aluminum wires shall conform to prescribed the requirements. The rated strength of a completed conductor shall be taken as the aggregate strength of the aluminum and aluminum-clad steel components. The strength contribution of the aluminum-clad steel core wires shall be taken as the percentage according to the number of layers of aluminum-clad steel wires. Tests for mechanical and electrical properties of aluminum wires shall be made before stranding. All aluminum wires composing the conductors shall be capable of meeting the bending properties after stranding, as stated in the referenced ASTM documents.

This abstract is a brief summary of the referenced standard.

1. Scope

1.1 This specification covers concentric-lay-stranded conductors made from round aluminum 1350-H19 (extra hard) aluminum wires and round aluminum-clad steel core wires for use as overhead electrical conductors (Explanatory Note 1 and Note 2).

1.2 The SI values of density and resistivity are to be regarded as standard. For all other properties the inch-pound units are regarded as standard and the SI units may be approximate.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
