Title
Code Words for Underground Distribution Cables
The Aluminum Association Inc.
Publication Date:
Jan 1, 1999
Scope:
This booklet lists Code Words for secondary (600 volt) underground
distribution (UD) cables, and
identifies their constructions. Reference to primary (5, 15, and 25kV)
cables has been deleted as
the designs included are not current with the styles used today.
It has been the practice for many years to employ code words for bare,
covered (weatherproof), and
low voltage secondary and neutral supported service drop insulated
cables used in overhead systems.
(Refer to The Aluminum Association publication "Code Words for
Aluminum Conductors".) With the
rapid expansion in the use of UD cables in the last decade and the
proliferation in the sizes,
types and constructions available, the advantages of establishing code
words for these products was
apparent. Consequently, manufacturers have assigned code words to UD
cables as a convenient means
of concisely defining specific cable designs (conductor size,
insulation type, voltage rating,
neutral configuration and size, number of phase conductors and type of
assembly). The use of code
words in catalogs, orders, invoices and other production and sales
records not only provides a
brief identification for UD cables but also minimizes the chance for
errors in transcribing the
longer, detailed description for each cable.
Learning from the experience gained in standardizing the code word
system for overhead products,
the same basic principles were employed in the assignment of code
words for UD cables accepted by
and registered with the Electrical Technical Committee of The Aluminum
Association.
This booklet lists UD cable code words and identifies their
constructions, includes the details of
the code word system and outlines the procedure for registering new
code words. Preceding the
tables identifying the UD cable constructions is a list of
characteristics that are implied by the
code word itself without any suffix. This is followed by a list of the
suffixes to be used with the
code words for designating variations in those characteristics.
Selected examples show how the
system works.
The 600V UD cables referenced in Tables A through H2 are manufactured
to the applicable ASTM, UL,
and ICEA specifications. Following the tables is an alphabetical
listing of all UD cable code words
with references to the pages where the cable data may be found.
The booklet concludes with a list of standards and specifications
relating to UD cables which are
endorsed by The Aluminum Association.
All Aluminum Association published standards, data, specifications and
other material are reviewed
at least every five years and revised, reaffirmed or withdrawn. Users
are advised to contact the
Aluminum Association to ascertain whether the information in this
publication has been superseded
in the interim between publication and proposed use.
