1、Designation: B701/B701M 06B701/B701M 13Standard Specification forConcentric-Lay-Stranded Self-Damping AluminumConductors, Steel Reinforced (ACSR/SD)1This standard is issued under the fixed designation B701/B701M; the number immediately following the designation indicates the yearof original adoption
2、 or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers concentric-lay-stranded self-damping aluminum cond
3、uctor, steel-reinforced (ACSR/SD), and itscomponent wires for use as overhead electrical conductors (Explanatory Notes 1 and 2).1.2 The values stated in inch-pound or SI units are to be regarded separately as standard. Each system shall be usedindependently of the other. Combining values from the tw
4、o systems may result in non-conformance with the specification. Forconductor sizes designated by AWG or kcmil, the requirements in SI units have been numerically converted from correspondingvalues stated or derived in inch-pound units. For conductor sizes designated by SI units only, the requirement
5、s are stated or derivedin SI units.1.2.1 For density, resistivity, and temperature, the values stated in SI units are to be regarded as standard.NOTE 1ACSR/SD is designed to control aeolian vibration by integral damping. The conductors consist of a central core of a round steel wire or wiressurround
6、ed by two layers of trapezoidal aluminum 1350-H19 wires or two layers of trapezoidal aluminum 1350-H19 wires and one layer of roundaluminum 1350-H19 wires (Fig. 1). The trapezoidal-wire layers are separated from each other and from the steel core by two small annular gaps thatprovide the conductors
7、self-damping characteristics. The round aluminum wires are in tight layer contact between themselves and the underlyingtrapezoidal wire layer. Different strandings of the same size of conductor are identified by type, which is the approximate ratio of steel area to aluminumarea, expressed in percent
8、 (Table 1 and Table 2).NOTE 2The aluminum and temper designations conform toANSI Standard H 35.1.Aluminum 1350 corresponds to UNSA91350 in accordance withPractice E527.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibilityo
9、f the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatorylimitations prior to use.2.
