1、Designation: B901 04 (Reapproved 2011)Standard Specification forCompressed Round Stranded Aluminum Conductors UsingSingle Input Wire Construction1This standard is issued under the fixed designation B901; the number immediately following the designation indicates the year oforiginal adoption or, in t
2、he case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers aluminum 1350-H19 (extrahard), 1350-H16 or -H26 (34 hard),
3、1350-H14 or -H24 (12hard), 1350-H142 or -H242 (12 hard), and aluminum alloy8XXX series as listed in Specification B800 for tempers “O”and H1X or H2X, bare stranded conductors composed of oneor more roller shaped or die compressed layers of helicallylayed wires. The conductors are for general use for
4、 electricalpurposes (Explanatory Notes 1 and 2).NOTE 1For the purposes of this specification, single input wire (SIW)construction is defined as follows: a stranded conductor design method-ology that varies the number of wires within a range of conductor sizes inorder to permit that range of conducto
5、r sizes to be constructed from asingle wire size.1.2 The SI values for resistivity are regarded as standard.For all other properties, the inch-pound units are regarded asstandard and the SI units may be approximate.NOTE 2Prior to 1975, aluminum 1350 was designated as EC alumi-num.NOTE 3The aluminum
6、and temper designations conform to ANSIH35.1. Aluminum 1350 corresponds to Unified Numbering SystemA91350 in accordance with Practice E527. Aluminum alloys in the 8000series correspond to Unified Numbering System A98XXX in accordancewith Practice E527.NOTE 4This specification also permits conductors
7、 for use as coveredor insulated electrical conductors.NOTE 5Sealed conductors, which are intended to prevent longitudinalwater propagation and are further covered/insulated, are also permittedwithin the guidelines of this specification.2.

Mass and Electrical Resistance11.1 The mass and electrical resistance of a unit length of astranded conductor are a function of the length of lay. Theapproximate ma

When dcresistance is measured at other than 20C, it is to be correctedby using the multiplying factor given in Table 4.11.3 For conductors to be used in covered or insulated wiresor cables, dc resistance measure
