Designation:B231/B231M–04
Standard Specification for
Concentric-Lay-Stranded Aluminum1350Conductors1
This standard is issued under thefixed designation B231/B231M;the number immediately following the designation indicates the year of original adoption or,in the ca of revision,the year of last revision.A number in parenthes indicates the year of last reapproval.
A superscript epsilon(e)indicates an editorial change since the last revision or reapproval.
This standard has been approved for u by agencies of the Department of Defen.
1.Scope
1.1This specification covers aluminum1350-H19(extra hard),1350-H16or-H26(3⁄4hard),1350-H14or-H24(1⁄2 hard),and1350-H142or-H242(1⁄2hard),bare concentric-lay-stranded conductors constructed with a straight round central wire surrounded by one or more layers of helically layed wires. The conductors are for general u for electrical purpos (Explanatory Note1and Note2).
1.2The values stated in inch-pound or SI units are to be regarded parately as standard.The values in each system are not exact equivalents;therefore,each system shall be ud independently of the other.Combining values from the two systems may result in nonconformance with the specification.
1.2.1For density,resistivity and temperature,the values stated in SI units are to be regarded as standard.
N OTE1—Prior to1975,aluminum1350was designated as EC alumi-num.
N OTE2—The aluminum and temper designations conform to ANSI Standard H35.1/H35.1M.Aluminum1350corresponds to Unified Num-bering System A91350in accordance with Practice E527.
N OTE3—Sealed conductors that are intended to prevent longitudinal water propagation and are further covered/insulated are also permitted within the guidelines of this specification.

3.Classification
3.1For the purpo of this specification,conductors are classified as follows(Explanatory Note1and Note2):
3.1.1Class AA—For bare conductors usually ud in over-head lines.
3.1.2Class A—For conductors to be covered with weather-resistant materials,and for bare conductors where greater flexibility than is afforded by Class AA is required.Conductors intended for further fabrication into tree wire or to be insulated

and laid helically with or around aluminum or ACSR mesn-gers,shall be regarded as Class A conductors with respect to direction of lay only(e7.4).
3.1.3Class B—For conductors to be insulated with various materials such as rubber,paper,varnished cloth,and so forth, and for the conductors indicated under Class A where greater flexibility is required.
3.1.4Class C and D—For conductors where greater flexibility is required than is provided by Class B conductors.

4.Ordering Information
4.1Orders for material under this specification shall include the following information:
4.1.1Quantity,
4.1.2Conductor size:square millimetres,if cross-ctional area is specified as a requirement(Section8and Tables1-4), 4.1.2.1Conductor size,number,and diameter of wires for Class B,C,or D conductors,if cross-ctional area is not specified as a requirement(e8.2),
4.1.3Class(e3.1),
4.1.4Temper(e
石头剪子布5.1),
4.1.5Details of special-purpo lays,when required(e7.2 through7.5),
4.1.6Special tension tests if required(e14.1and1
5.1), 4.1.7Package size and type(e17.1and Table1or Table 2),
4.1.8Special package marking,if required(Section19), 4.1.9Heavy wood lagging,if required(e18.2),
4.1.10Place of inspection(Section17),and
4.1.11Method of cross-ctional area determination if not optional(e12.1).
5.Requirements for Wires
5.1Aluminum wire employed in Class AA and A conduc-tors shall be1350-H19,unless otherwi specified.The pur-char shall designate the temper of conductors of Class B, C,and D.
5.1.1For conductor tempers other than1350-H19,when temper designations are not more specific in the inquiry and purcha order,the manufacturer shall have the following options on manufacturing method:
5.1.1.1Strand the conductor from wires drawn tofinal temper;
5.1.1.2Strand the conductor from wires drawn to H19 temper and annealed tofinal temper prior to stranding;
5.1.1.3Strand the conductor from1350-H19wires and anneal the stranded conductor tofinal temper.
5.2Before stranding,the aluminum wire ud shall meet the requirements of Specifications B230/B230M or B609/ B609M,whichever is applicable.
5.3All wires in the conductor shall be of the same temper.
6.Joints
6.1Only cold-pressure joints or electric-butt,cold-upt joints may be made in the six outerfinished wires of(1)Class AA conductors compod of ven wires or(2)Class A conductors compod of ven wires ud in overhead lines.In other conductors,electric-butt welds,cold-pressure welds,or electric-butt,cold-upt welds may be made in thefinished wires composing conductors,but such welds shall not be clor than prescribed in Table5(Explanatory Note3).
7.Lay
7.1For Class AA conductors compod of ven wires or more,the preferred lay of a layer of wires is13.5times the outside diameter of that layer,but the lay shall be not less than 10nor more than16times this diameter.
7.2For all other class the lay of a layer of wires shall be not less than8nor more than16times the o
utside diameter of that layer,except that for conductors compod of37wires or more,this requirement shall apply only to the two outer layers. The lay of the layers other than the two outer layers shall be at the option of the manufacturer,unless otherwi agreed upon.
7.2.1For conductors to be ud in covered or insulated wires or cables,the lay length of the wires shall not be less than 8nor more than16times the outer diameter of thefinished conductor.For conductors of37wires or more,this require-ment shall apply to the wires in the outer two layers.The lay of the layers other than the outer two layers shall be at the option of the manufacturer,unless otherwi agreed upon. 7.3Other lays for special purpos shall be furnished by special agreement between the manufacturer and the purchar (Explanatory Note4).
