Title
Code Words for Overhead Aluminum Electrical Conductors
The Aluminum Association Inc.
Publication Date:
Jan 1, 1999
Scope:
For many years manufacturers of electrical conductors have assigned
code words to their products to
aid in identifying the different types and sizes of conductors in
catalogs, orders, invoices and
other production and sales records. As the number of different types
and sizes of conductors
increased over the years, the number of code words increased until by
1960 more than 1,200 such
words were in use. In some instances the same words came to be used to
designate more than one
conductor. With more new constructions, new types of insulation,
different tempers and other
variations in the offing, there was a potential need for many more
code words.
Recognizing this situation, the Technical Committee on Electrical
Conductor of The Aluminum
Association's Electrical Technical Division in 1960 initiated a study
aimed at reducing the number
of code words required for these products. During its study the
Subcommittee considered several
different systems. Some would have accomplished the desired reduction
in number of code words but
were considered too complicated for practical use. The system finally
adopted retains the code
words now in use but provides for designating variations in
construction, temper, and type of
covering or insulation by the use of suffixes to existing code words,
thus greatly reducing the
number of new code words that otherwise would be required in the
future.
The conductors referenced in Tables 1 through 47 are manufactured in
accordance with applicable
ASTM Specifications. It is the Technical Committee's recommendation
that these codes words should
not be used for conductors manufactured in accordance to
specifications other than ASTM.
This booklet lists the code words that have been registered with The
Aluminum Association, outlines
the procedure for registering new code words and includes the details
of the system. Preceding each
group of tables covering conductors of the same general type is a list
of the characteristics of
each conductor that are implied by the code word itself without any
suffix. This is followed by a
list of the suffixes to be used following the code words for
designating variations in those
characteristics. Selected examples show how the system works.
Tables have also been added for British and Canadian code words. This
has been added for
informational purposes only. The code words used in these tables are
not controlled by the Aluminum
Association.
Following the tables is an alphabetical listing of the code words with
references to the specific
table where the conductor data may be found. In addition, for
informational purposes, the list also
includes code words used for UD cable, copper conductors and others
used in Canada and Great
Britain to designate aluminum conductors made in those countries.
Details of construction for UD cable code words are covered in CODE
WORDS FOR UNDERGROUND
DISTRIBUTION CABLES, available from the Aluminum Association.
