Abstract

This specification covers zinc-coated (galvanized), zinc-aluminum-mischmetal alloy-coated, and aluminum-coated (aluminized) stranded steel wire core inserted for use in aluminum conductors, steel reinforced (ACSR). Prior to stranding, the metallic coated steel wire to be used in the production of the stranded core shall meet all of the requirements of the appropriate specification. Requirements for (1) coated steel wire joints, (2) stranding of the core such as lay length and lay direction, (3) construction of ACSR, and (4) tensile properties of stranded core are detailed. The standard stranded core lengths and methods of determining rated strength and calculating loads are given.

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 7-wire, 19-wire, 37-wire, and 61-wire zinc-coated (galvanized), zinc-5 % aluminum-mischmetal alloy-coated or aluminum clad stranded steel core intended for use in overhead electrical conductors.

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.

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