Standard Specification for Concentric-Lay-Stranded Aluminum Conductors, Coated-Steel Reinforced (ACSR)
 N B232/B232M

Annotation

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).

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

ACSR/GA or ACSR/GA2—ACSR using Class A zinccoated steel wire,

ACSR/GC or ACSR/GC2—ACSR using Class C zinccoated steel wire,

ACSR/MA or ACSR/MA2—ACSR using Class A Zn- 5A1-MM coated steel wire,

ACSR/HS or ACSR/GA3—ACSR using Class A zinccoated high-strength steel wires,

ACSR/MS or ACSR/MA3—ACSR using Class A Zn- 5A1-MM coated high-strength steel wires,

ACSR/GA4—ACSR using Class A zinc-coated extrahigh- strength steel wires,

ACSR/MA4—ACSR using Class A Zn-5A1-MM coated extra-high-strength steel wires,

ACSR/GA5—ACSR using Class A zinc-coated ultrahigh- strength steel wires,

ACSR/MA5—ACSR using ClassAZn-5Al-MM coated ultra-high-strength steel wires.

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.
