1、Designation: B701/B701M 13 (Reapproved 2018)Standard 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 ado

2、ption 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

3、 conductor, steel-reinforced (ACSR/SD),and its component wires for use as overhead electrical conduc-tors (Explanatory Notes 1 and 2).1.2 The values stated in inch-pound or SI units are to beregarded separately as standard. Each system shall be usedindependently of the other. Combining values from t

4、he twosystems may result in non-conformance with the specification.For conductor sizes designated by AWG or kcmil, the require-ments in SI units have been numerically converted fromcorresponding values stated or derived in inch-pound units. Forconductor sizes designated by SI units only, the require

5、mentsare stated or derived in SI units.1.2.1 For density, resistivity, and temperature, the valuesstated in SI units are to be regarded as standard.NOTE 1ACSR/SD is designed to control aeolian vibration by integraldamping. The conductors consist of a central core of a round steel wire orwires surrou

6、nded by two layers of trapezoidal aluminum 1350-H19 wiresor two layers of trapezoidal aluminum 1350-H19 wires and one layer ofround aluminum 1350-H19 wires (Fig. 1). The trapezoidal-wire layers areseparated from each other and from the steel core by two small annulargaps that provide the conductors

7、self-damping characteristics. The roundaluminum wires are in tight layer contact between themselves and theunderlying trapezoidal wire layer. Different strandings of the same size ofconductor are identified by type, which is the approximate ratio of steelarea to aluminum area, expressed in percent (

8、Table 1 and Table 2).NOTE 2The aluminum and temper designations conform to ANSIStandard H 35.1. Aluminum 1350 corresponds to UNS A91350 inaccordance with Practice E527.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of

9、 the user of this standard to establish appro-priate safety, health, and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accor-dance with internationally recognized principles on standard-ization establi
