ASTM B232/B232M-22 - 1.12.2022
 
1. Scope

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

1.2?ACSR covered by this specification has nine types of coated steel core wire which are designated by abbreviations as follows (Explanatory Note 2):

1.2.1?ACSR/GA or ACSR/GA2ACSR using Class A zinc-coated steel wire,

1.2.2?ACSR/GC or ACSR/GC2ACSR using Class C zinc-coated steel wire,

1.2.3?ACSR/MA or ACSR/MA2ACSR using Class A Zn-5A1-MM coated steel wire,

1.2.4?ACSR/HS or ACSR/GA3ACSR using Class A zinc-coated high-strength steel wires,

1.2.5?ACSR/MS or ACSR/MA3ACSR using Class A Zn-5A1-MM coated high-strength steel wires,

1.2.6?ACSR/GA4ACSR using Class A zinc-coated extra-high-strength steel wires,

1.2.7?ACSR/MA4ACSR using Class A Zn-5A1-MM coated extra-high-strength steel wires,

1.2.8?ACSR/GA5ACSR using Class A zinc-coated ultra-high-strength steel wires,

1.2.9?ACSR/MA5ACSR using Class A Zn-5Al-MM coated ultra-high-strength steel wires.

1.3?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.

1.4?This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
