1、Designation: B911/B911M 12 (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

2、 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 coversACSR Twisted Pair Conductor(ACSR/TP) for use as overhead electric conductors (see Notes1 and

3、 2).NOTE 1The 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.NOTE 2There ar

4、e registered trademark 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 equivalent

5、s; therefore, eachsystem 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

6、derived in inch-pound units. 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 concern

7、s, if any, associated with its 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.

11、t Conductors5.1 Before twisting, the component 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 an

12、d thetake-up reel with normal take-up tension on the ACSR/TP.NOTE 3The 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 un

Mechanical and Electrical Tests11.1 Tests for the electrical and mechanical properties shallbe made on the component conductors

The ratedstrength of the completed ACSR/TP shall be two times thebreaking strength of the

39、component conductor that had thelowest breaking strength.11.3 The critical aspect of ACSR/TP conductor is that thecomponent conductors be of equal length and tension in thecompleted ACSR/TP. To test for this condition during thetwisting process a mark (using felt tip pin or spray paint) is tobe made

These two marks shall beobserved and followed visually during the twisting and to thetake-up reel. If the marks move back and forth relative to eachother les
