Description of ASTM-B400 2001ASTM B400-01Historical Standard: Standard Specification for Compact Round Concentric-Lay-Stranded Aluminum 1350 ConductorsASTM B400Scope 1.1 This specification covers aluminum 1350-H19 (extra hard), 1350-H16 or -H26 ([n ]hard), 1350-H14 or -H24 (½ hard) and 1350-H142 or -H242 (½ hard) bare compact-round concentric-lay-stranded conductors made from round or shaped wires for use as uninsulated electrical conductors or in covered or insulated electrical conductors. These conductors shall be composed of a central core surrounded by one or more roller or die compacted layers of helically applied wires (Explanatory Note 1 and Note 2). 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 non-conformance with the specification. For conductor sizes designated by AWG or kcmil sizes, the requirements in SI units are numerically converted from the corresponding requirements in inch-pound units. For conductor sizes designation 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. Note 1--Prior to 1975, aluminum 1350 was designated as EC aluminum. <>Note 2--The aluminum and temper designations conform to ANSI Standard H35.1. Aluminum 1350 corresponds to Unified Numbering System A91350 in accordance with Practice E527.Keywords aluminum conductors; aluminum electrical conductor; compact round stranded conductors; concentric-lay-stranded conductors; electrical conductor; electrical conductor-aluminum; stranded conductors ICS Code ICS Number Code 29.240.20 (Power transmission and distribution lines) DOI: 10.1520/B0400-01 The following editions for this book are also available...This book also exists in the following packages...Subscription InformationMADCAD.com ASTM Standards subscriptions are annual and access is unlimited concurrency based (number of people that can access the subscription at any given time) from single office location.
