1、Designation:B911/B911M12(Reapproved 2016)Standard Specification forACSR Twisted Pair Conductor(ACSR/TP)1This standard is issued under the fixed designation B911/B911M;the number immediately following the designation indicates the yearof original adoption or,in the case of revision,the year of last r
2、evision.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 ACSR Twisted Pair Conductor(ACSR/TP)for use as overhead electric conductors(see Notes1 and 2).NOTE1The
3、 conductor is fabricated from two component ACSRconductors of the same size twisted helically around each other.Thisconductor is identified by the code name of the component ACSRconductor followed by/TP or the size and type of the component ACSRconductor followed by/TP.NOTE2There are registered trad
4、emark symbols that are also used toidentify the twisted pair notation.Consult cable manufacturers foradditional details.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsys
5、tem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.1.2.1 For conductor sizes designated by AWG or kcmil,therequirements in SI units have been numerically converted fromcorresponding values stated or derived in inch-pound u
6、nits.Forconductor sizes designated by SI units only,the requirementsare stated or derived in SI units.For density,resistivity,andtemperature,the values stated in SI units are to be regarded asstandard.1.3 This standard does not purport to address all of thesafety concerns,if any,associated with its
7、use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 The following documents of the issue in effect on thedate of material purchase form a part

11、ent conductors shall con-form to the requirements of Specification B232/B232M.6.Twist6.1 The component conductors shall be twisted about them-selves with a complete twist every 9 ft 6 1 ft.This twist lengthshall be measured between the twisting machine and thetake-up reel with normal take-up tension
12、 on the ACSR/TP.NOTE3The twist length can be altered as the ACSR/TP is wound uponto the take-up reel.It may not have the same twist length as when theTP is removed from the reel.6.2 The direction of the twist shall be left hand.1This specification is under the jurisdiction of ASTM Committee B01 onEl
