Full Description
1.1This 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).
1.2ACSR covered by this specification has nine types of coated steel core wire which are designated by abbreviations as follows (Explanatory Note 2):
1.2.1ACSR/GA or ACSR/GA2-ACSR using Class A zinc-coated steel wire,
1.2.2ACSR/GC or ACSR/GC2-ACSR using Class C zinc-coated steel wire,
1.2.3ACSR/MA or ACSR/MA2-ACSR using Class A Zn-5A1-MM coated steel wire,
1.2.4ACSR/HS or ACSR/GA3-ACSR using Class A zinc-coated high-strength steel wires,
1.2.5ACSR/MS or ACSR/MA3-ACSR using Class A Zn-5A1-MM coated high-strength steel wires,
1.2.6ACSR/GA4-ACSR using Class A zinc-coated extra-high-strength steel wires,
1.2.7ACSR/MA4-ACSR using Class A Zn-5A1-MM coated extra-high-strength steel wires,
1.2.8ACSR/GA5-ACSR using Class A zinc-coated ultra-high-strength steel wires,
1.2.9ACSR/MA5-ACSR using Class A Zn-5Al-MM coated ultra-high-strength steel wires.
1.3The 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.
1.4This 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.
1.5This 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.
