    New Specification for Electrical Overhead Conductor Code Word Names

    (What is a Work Item?)

    Developed by Subcommittee: B01.07 | Committee B01 | Contact Staff Manager


    1. Scope

    1.1 This specification lists code word names for bare overhead electrical conductors that are recognized in North America. A procedure has been outlined for adding additional code word names to this specification. Code word names have been in existence for many years describing various conductor constructions used in North America, Europe, and elsewhere in the world. Their origin is not clearly understood. The historical basis of this specification originates from code word names developed years ago by member utility companies that participated in the U.S. Aluminum Association, Technical Committee. 1.2 The code word names are grouped into tables of like constructions. The code word name construction can be modified with the use of suffix modifiers that identify additional construction variations. For example, the type of steel core material used in an ACSR type of conductor may be modified with the letter designation /GA3 denoting the strength and type of coating for the steel core material. 1.3 The tables provide the applicable ASTM International standard for which the conductor construction may be built. For conductors that are unique to use in Canada, the applicable CSA International standard is referenced. 1.4 The tables include code word names that are referenced in Canadian CSA and European CENELEC standards. The information is believed to be correct, however, the user of this specification is encouraged to consult the applicable CSA or CENELEC standard for confirmation.

    There needs to be viable method to register new codeword names and provide a working index to identify the conductor construction. The codeword name is linked to a specific conductor design outlining the dimensions and make-up composition of the stranded conductor.


    aluminum conductor; concentric-lay-stranded aluminum conductor; electrical conductors; electrical conductors, aluminum; steel-reinforced conductors; stranded aluminum conductors

    The title and scope are in draft form and are under development within this ASTM Committee.
