Section II
Bare Aluminum Wire and Cable
Chapter 4
Product Identification and Data
This chapter supplements Chapter 3 with tables of
mechanical and electrical properties of specified sizes of
commercially available bare conductors. Some of the bare­
conductor data is also applicable to conductors that are
covered with weather-resistant materials. which provide
moderate protection against corrosion and abrasion but
have no voltage rating, Further information regarding
weather-resistant coverings is in Chapters 7 and 8.
Serricc Application of Bare Conducrors
The tvpicat electric power svstem has many applications
for bare stranded conductors, from the strain bus at the
generation plant substation through the transmission con­
ductors and overhead ground wires to the distribution sys­
tem and the neutrals for service drops.
Product Classification of
Bare Aluminum Conductors
ACSR/TW (Shaped Wire):
1350-H19 Trapezoidal wire
ACAR (Aluminum Conductor Alloy Reinforced):
1350-H19 and Strands of 6201-T81
Aluminum-Clad Steel Wire and Strand
3. Expanded core designs for EHV generally use 1350­
H19 strands for conductance along with steel rein­
forcement. Expansion is by open helices of aluminum
wires, flexible concentric tubes or combinations of
aluminum wires and fibrous ropes.
No tables of properties of EHV cables are included
herein because each project requires special analysis, and
design practice is not as yet standardized. A typical exam­
ple of an expanded-core cable is shown in Fig. 3-6.
NOle: The tlbove list comprises cond"Jctofs that ordinarily are
installed in :,are condition: that is. without covering or it'lSuJa
tion. As a convenience, tables also are included in this chapter
thut list modificutions of (he hnsic bare conduetOfs which ordi­
narily are to be covered or inSUlated before use. Thus, all~alumiw
num condLlctors listed as with B. C. and D strandin!! ore usually
covered or insulated when in use, though may be bare for short
lengths in apparatus, terminal leads, etc.
M
The alloy and conductor-type designations used for bare
aluminum conductors are described in Chapter 3. They
arC summarized below to aid reference to the: various
tables herein:
1. Homogeneous designs ofaluminum conductor
consists of:
AAC (see Aluminum Conductor):
1350-H19 (Standard Round of Compact Round)
AACrrW (Shaped Wire):
l380-H19 (Trapezoidal wire)
AAAC (see Aluminum Alloy Conductor):
6201-T8l
2. Composite designs of aluminum conductor
consist of:
ACSR (Aluminum Conductor Steel Reinforced):
l350-H19 Aluminum strands with:
Class A (Standard Weight) Coated
Galvanized Steel Core
(ACSR)
ACSR (Compact Round):
1350-H19 Strand. Outside diameter reduced
after stranding.
Tables 4-26 and 4-27 covering Aluminum Unilay 19 wire
conductors and the 8000 series Aluminum Alloy conduc­
tors are included in this chapter in order to list the details
of the various strandings for the bare condition. For
information on their eventual applications reference should
be made to the chapters in Section 3 on "Covered and
Insulated Wire and Cable."
Product Identification
For ease of reference. many of the various conductors
are identified not only by size and description. but also
by an industry code word, as registered with The Alumi­
num Association. The word may be that of a bird, flower,
fish. etc. to which a suffix may be added to denote product
variations. Other designations associated with the con­
ductor such as AAC, AAAC, ACSR, ACAR. and the
4·1
bare aluminum wire and cable
alloy temper designations, such as 1350-H19 and 6201­
T81, have been explained in previous chapters. Use of
the code word system and possible variations is described
in the Aluminum Association pUblication "Code Words
for Aluminum Electrical Conductors."
Common practice in conductor designation utilizes as­
sumptions and abbreviations.
A. For 1350 aluminum, the Hl9 temper is assumed.
For 6201 alloy, the T81 temper is assumed.
For ACSR, the core is assumed to have standard­
weight galvanized class A steel core and 1350-HI9
aluminum wires.
B. Suffix notations that designate other than what is
implied in A (above):
For 1350-aluminum and Temper (for physical properties,
see Table 1-1)
1350-0 designates fully annealed wire.
1350-H12 and -H22 designate \<i-hard wire.
1350-H14 and -H24 designate V,-hard wire.
type ofconductor than ordinarily would be expected. This
comes about because replacement ofone type ofconductor
by another is facilitated if they have equal dc resistance,
or if their outside diameters are equai. Thus, the odd-size
477.0 kcmil 1350-HI9 aluminum conductor has approxi­
mately the same dc resistance as 300.0 kcmil copper, and
the 795.0 kcmil conductor corresponds to 500.0 kcmil
copper. Similarly, some AAAC and ACAR conductors
are sized for diameter equivalence with certain sizes of
ACSR.
The wide range of breaking strengths of a given size of
ACSR because of variations of steel-to-aluminum ratios
also adds to the conductors available for transmission line
design.
The trend in recent years, however, is toward reducing
the number of generally available sizes that are based on
equivalence with other conductors, and SOme larger-than­
AWG all-aluminum conductois are now sized on the
basis of 50,000 emil increments. Hence each is not exactly
the equivalent of any other type of conductor as to conduc­
tance Or diameter.
1350-H 16 and -H26 designate %-hard wire.
For ACSR
GB designates Class B galvanized steel core wire.
GC designates Class C galvanized steel core wire.
AZ designates aluminized steel core wire.
AW designates aiuminllm-clad steel core wire.
"Camp" designates compact stranding.
Technical Data and Catalog In/ormalion
The construction and properties of many kinds of bare
aluminum conductors are covered by individual ASTM
specifications and unless otherwise noted, data in this
chapter are based on these specifications. Specification
numbers and descriptions at time of this publication are
shown in Table 4-1. Individual ASTM Specifications and a
book, ASTM volume 02.03 Electrical Conductors, which

1. Data shown are subject to normal manufacturing tolerances.
2. Class AA stranding is usually specified for bare conductors used on overhead lines. Class A stranding is usually specified for conductors to be
covered with weatheNesistant (weatherproof) materials and used for bare conductors where greater flexibility is required than afforded by Class
AA The direction of lay of the outside layer of wires with Class AA and Class A will be right~hand, unless otherwise specified.

1, Direct current (de) resistance is based on 16,946 ohm-cmilfft at 20"C for 1350 aluminum nominal area of conductor with standard stranding
increments ASTM 6231,
2. Altemating current (ae) resistance is based on de resistance corrected for temperature, using 0.00404 as temperature coefficjent of resistMty
per degrees C" at 20~ and for skin effect
3. For ampacity ratings of bare conductors, see Ftg. 3--11 and

Direct current (de) resistance is the same as given in Tables 4-6 and 4~7 for corresponding sizes; ac resistance and reaciance may be taken as
the values for Class A conductors of equivalent size, as the slight difference caused by stranding variation is not significant in usual
engineering calculations. For ampaclty ratings of bare conductors, interpolate from Figs. 3~11 and 3-12.

2. Direct current (de) resistance is computed on same basis as that of Table 4-6.
3, The ampacity ratings of oompacHound bare conductors differ slightly from those of regular types of same sizes because of
reduction of exposed surface, but the compacting in the cabte somewhat offsets this by improving thermal transfer within the cable,
4, The values of GMR and inductive and capacitive reactances listed in Tables 4-6 and 4-7 may be used for compacted cable without
significant error for usual design applications.

1. Data shown are subject to normal manufacturing tolerances.
2. Direct current (de) resistance i. based on 19,755 ohm-cmillft. at 20'C, 52.5% lACS, with standard stranding increment of 2 percent.
3. Alternating current {ac) is based on de resistance corrected for temperature, using 0.00347 as temperature coefficient of resistivity per degree
C at 20'C, and for skin effect.
4. For ampacity ratings of bare conductors, see Figs. 3·11 and 3-12 and adjust values according to method described in accompanying text.
5. As the values of GMR and inductive and capacitive reactances of any all-aluminum stranded cable of a specified outside diameter are closely
equal. the values of GMR, etc., or Tables 4~6 and 4-7 may be used fOr the above table if the diameters are equa1. It the same diameter is not
found in Tables 4-6 and 4-7 as the above table, interpolation from the nearest diameters readily obtains the desired GMR, etc.

These conductors have right-hand lay of outer layer. unless otherwise specified. ASTM B 399 lists both Class AA and Class A
stranding (see footnote 2 of Table 4-5 for explanation). As the difference is slight, it is trade custom to supply cables that meet the
Class AA requirements unless otherwise specified. and the listings herewith apply to either Class AA or Class A.

1. Direct current (de) resistance is based on 16.946
2. Alternating current (ac) resistance is based on the resistance corrected for temperature using 0.00404 as temperature coefficient of resistiVity per
degree C for aluminum and 0.0029 per degree C for steel, and for skin effect.
3. The effective ac resistance of 3-layer ACSR increases with current density due to core magnetization. See Chapter 3 for details.
4. For ampacity ratings of bare conductors, see Figs. 3-13 and 3-14.

Physical and Electrical Properties
NOTE: For a cable of same dimensions and Code Word, the values in Table 4-14 (A and B) may be used for cross-sectonal
area of aluminum wires; total cross-sectional; the number of wires and diameter of wires in strand; diameter of complete
cable; and diameter of core. The values in Tables 4-15 and 4-16 may be used for GMR, inductive reactance, and capacitive
reactance. For approximate ampacity, multiply value from Fig. 3-13 or 3-14 by the square root of the ratio
of the total aluminum area to the aluminum wire area in circular mils. Thus, for Penguin at 60" rise Fig. 3-13 shows
305 amp. Hence, 305 X (220,4601211,600)'"

1. The values listed above differ from the corresponding ones of tables for ACSA because the COnductivity of the aluminum in the thick cladding
of the core wires is taken into account Electrical properties of the aluminum wires are those of ASTM B 230 and of the core wires are those
of ASTM B 502.
2, The single and three-layer ACSR/AW ae resistances have not been corrected for the magnetic effect of the core wire. See text of Chapter 3,

1. Data shown above are subject to normal manufacturing tolerance.
2. Applicable footnotes of Table 4-15 and 4-16 also apply to the above table; that is,the magnetizing currents for single-layer cables are based on
10010 of specified current for 25i>C, 75%. for sooe. and 100% tor 7ftC. Allowance should also be made for GOre magnetization in the
3&-wire cables.
3. For ampacity ratings see Figs. 3·13 and 3·14 and adjust according to the methOd described in the accompanymg text.
4, Electrical data will be close enough to the equivalent size of Ilf.>n·compacted conductor that data for those conductors may be used for practical
purposes,

Data stlown are subject to normal manufacturing tolerances.
AlUminum strands are of a trapezoidal shape and thus round wire sjze is not shown.
Rated strengths of the complete conductors are calculated In accordance with ASTM B 779.
Weights are based on 1350 aluminum and Class A zinc-coated steel.
The type no, is the ratio of the steel to aluminum areas expressed as a percentage.

------".~--
2. Alternating current (ac) resistance is based on de resistance corrected for temperature using 0.00409 as temperature coefficient of resistIVity
per degree G for aluminum and 0.0029 per degree G for steel. and for skin effect.
3. The effective ac resistance of a layer ACSRfTW increases with current density due to core magnetization. See Chapter 3 for details.
4. For ampaclty ratings of TW conductors, approximate values can be obtained from Figs. 3-13 and 3-14.

1. Direct current (de) resistance is based on 16.727 ohm-cmillft (62.0% lACS) at 20'C for nominal aluminum area of the conductors. and 129.64
ohm-cmiV~ (8.0% lACS) at 20'C for the nominal steel area.
2. Alternating current (ac) resistance Is based on de reSistance corrected for temperature using 0.00409 as temperature coefficient of resistivity
per deg,ee C for aluminum and 0.0029 per degree C lor steel, and lor skin effect.
3. The effective ac resistance of 3 layer ACSRt1W increases with current densIty due to core magnetizatiOn. See Chapter 3 for details.
4. For ampacity ,atings 01 TW conductors, apprOximate values can be obtained from Figs. 3-13 and 3-14.

2. Direct current (de) resistance is based on 16.946 ohm--cmil/ft. for
1350~H19
wires and 19.755 ohm-cmillft. for
6201~TB1
wire.
3. Alternating current (ao) resistance is based on de resistance corrected for temperature and skin effect
4. Properties of the individual wIres are those of ASTM B 230 and B 398.
5. As the values of GMR and inductive and capacitive reactances of any all~aluminum stranded cable of a specific outside diameter are closely
equal, the value of SMR, etc., of Tables 4-6 and 4-7 may be used for the above table if the diameters are equal. If the diameter is not found in
Tables 4-6 or 4-7 as in the above table, interpolation from the nearest diameters readily obtains the desired SMR, etc.

1, Data shown are subject to normal manufacturing tolerances.
2, Direct current (de) resistance is based on 17.002 ohm~cmilfft for aluminum wires and 51.01 ohm--crnil/ft for aluminum-clad wires in strands and
cladding.
3. Alternating current (ao) resistance is based on de resistance corrected for temperature and for skin effect.
4. Properties of the individual wires are those of ASTM B 502 and ASTM 6 230.
5. Ampacity for 6/1 ratio is directly listed in Figs. 3-13 or 3--14. This value is also conservative for other ratios because the increase of radiating
surface resutting from the larger diameter at the Other ratios is partly offset by increased 12R loss in the additional Sleel.
