1、Designation:B911/B911M05 Designation: B911/B911M 12Standard 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
2、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 ACSR Twisted Pair Conductor (ACSR/TP) for use as overhead electric conductors (see N
3、otes 1and 2).NOTE 1The conductor is fabricated from two component ACSR conductors of the same size twisted helically around each other. This conductor isidentified by the code name of the component ACSR conductor followed by /TP or the size and type of the component ACSR conductor followed by/TP.NOT
4、E 2There are registered trademark symbols that are also used to identify the twisted pair notation. Consult cable manufacturers for additionaldetails.1.2 The values stated in inch-pound either SI units or SIinch-pound units are to be regarded separately as standard. Each Thevalues stated in each sys
5、tem may not be exact equivalents; therefore, each system shall be used independently of the other.Combining values from the two systems may result in non-conformance with the specification. Forstandard.1.2.1 For conductor sizes designated by AWG or kcmil, the requirements in SI units have been numer
6、ically converted fromcorresponding values stated or derived in inch-pound units. For conductor sizes designated by SI units only, the requirements arestated or derived in SI units. 1.2.1ForFor density, resistivity, and temperature, the values stated in SI units are to be regarded asstandard.1.3 This
7、 standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatorylimitations prior to use.2.

Requirements for Component Conductors5.1 Before twisting, the component conductors shall conform to the requirements of Specification
16、B232/B232M.6. Twist6.1 The component conductors shall be twisted about themselves with a complete twist every 9 ft 6 1 ft. This twist length shallbe measured between the twisting machine and the take-up reel with normal take-up tension on the ACSR/TP.NOTE 3The twist length can be altered as the ACSR
17、/TP is wound up onto the take-up reel. It may not have the same twist length as when the TPis removed from the reel.6.2 The direction of the twist shall be left hand.7.
