ASTM B911/B911M-00

Standard Specification for ACSR Twisted Pair Conductor (ACSR/TP)

SCOPE
1.1 This specification covers ACSR Twisted Pair Conductor (ACSR/TP) for use as overhead electric conductors (see Notes 1and 2).
Note 1--The conductor is fabricated from two component conductors of the same size twisted around each other. This conductor is identified 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".
Note 2--There are registered trademark symbols that are also used to identify the twisted pair notation. Consult cable manufacturers for additional details.
1.2 The values stated in inch-pound or SI units are to be regarded separately as standard. Each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. For conductor sizes designated by AWG or kcmil, the requirements in SI units have been numerically converted from corresponding values stated or derived in inch-pound units. For conductor sizes designated by SI units only, the requirements are stated or derived in SI units.
1.2.1 For density, resistivity and temperature, the values stated in SI units are to be regarded as standard.
