Description of ASTM-B400 2008ASTM B400 - 08Standard Specification for Compact Round Concentric-Lay-Stranded Aluminum 1350 ConductorsActive Standard ASTM B400 | Developed by Subcommittee: B01.07 Book of Standards Volume: 02.03 ASTM B400Abstract
This specification covers aluminum1350-H19, 1350-H16 or -H26, 1350-H14 or -H24, and 1350-H142 or -H242 bare compact-round concentric-lay-stranded conductors made from round or shaped wires for use as uninsulated electric conductors or in covered or insulated electrical conductors. Joint shall be cold-pressure welded or electric-butt, cold-upset welded. The conductors shall conform to the required construction values of number of wires, nominal compact conductor diameter, nominal cross-sectional area and nominal DC resistance. Tests for the mechanical and electrical properties of wire composing the conductor shall be made before stranding and the conductors shall conform to the required values of breaking strength and rated strength. This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. 1. Scope
1.1 This specification covers aluminum 1350-H19 (extra hard), 1350-H16 or -H26 ([n ]hard), 1350-H14 or -H24 ( 1 / 2 hard) and 1350-H142 or -H242 ( 1 / 2 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 either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system 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 standard. Note 1Prior to 1975, aluminum 1350 was designated as EC aluminum. Note 2The aluminum and temper designations conform to ANSI Standard H35.1. Aluminum 1350 corresponds to Unified Numbering System A91350 in accordance with Practice E 527 ASTM Standards B230/B230M Specification for Aluminum 1350-H19 Wire for Electrical Purposes B231/B231M Specification for Concentric-Lay-Stranded Aluminum 1350 Conductors B263 Test Method for Determination of Cross-Sectional Area of Stranded Conductors B354 Terminology Relating to Uninsulated Metallic Electrical Conductors B609/B609M Specification for Aluminum 1350 Round Wire, Annealed and Intermediate Tempers, for Electrical Purposes E29 Practice for Using Significant Digits in Test Data to Determine Conformance with Specifications E527 Practice for Numbering Metals and Alloys in the Unified Numbering System (UNS) Other Documents NBS Handbook 100-Copper Wire Tables, of the National Bureau of Standards Available from National Technical Information Service (NTIS), 5285 Port Royal Rd., Springfield, VA 22161, http://www.ntis.gov.Keywords aluminum conductors; aluminum electrical conductor; compact round stranded conductors; concentric-lay-stranded conductors; electrical conductor; electrical conductor-aluminum; stranded conductors; Stranded aluminum electrical conductors--specifications; ICS Code ICS Number Code 29.240.20 (Power transmission and distribution lines) DOI: 10.1520/B0400-08 ASTM International is a member of CrossRef.
