25、of methods, equipment, and tools that havebeen found to be practical for the stringing of overhead transmission line conductors and overhead ground-wires. The guide also includes a comprehensive list of definitions for equipment and tools used in stringingand for stringing terms commonly employed. T

26、his guide does not address special conductors such as thoseused for river and canyon crossing. These conductors may be custom designed and often may require specialconsiderations.1.2 PurposeThe purpose of this guide is to present in one document sufficient details of present day methods, materials,a

27、nd equipment to outline the basic considerations necessary for maintaining safe and adequate control ofconductors during stringing operations. References are given in Clause 2 and the bibliography in Annex Afor those desiring more detailed information. Because the terminology used for many hardware

28、items andfor many stringing terms varies from place to place, a list of definitions is included to provide correlationand clarification of the terms most commonly employed.1.3 ApplicationThis guide is broad enough, yet specific enough, to be applicable to the stringing of conventional overheadtransm

29、ission conductors and overhead groundwires (OHGW) of the following types: AAAC, AAC,AACSR, ACAR, ACSR, ACSR/TW, CU, aluminum-clad steel OHGW, and galvanized steel OHGW.1Since stringing practices for different projects will be strongly influenced by the magnitude and nature ofeach project and by loca

30、l circumstances, alternate methods that have been successfully employed are pre-sented. Information contained in this guide may not be sufficient for certain special cases, such as whenstringing extremely long spans, severe line angles, high tensions, or special conductors. In these cases, themanufa

31、cturer should be consulted. The practices that are described in this guide provide for continuous con-trol of the conductor from the initial setup to the ready-for-service condition. Any legal requirements ofnational, state, or local regulations must, of course, be observed.1See 3.2 for definitions

32、of all acronyms.IEEEStd 524-2003 IEEE GUIDE TO THE INSTALLATION OF2Copyright 2004 IEEE. All rights reserved.The approach used within this guide is first to describe, in general terms, the stringing methods most com-monly employed, then the specific requirements of the various tools and equipment use

33、d. Finally, this guidedescribes the application of the methods and equipment used in the stringing process.2. ReferencesThis guide shall be used in conjunction with the following publications.

36、for equipment and procedures associated with the installation of overhead transmission lineconductors varies widely throughout the utility industry. Therefore, definitions (see 3.1) have been includedto provide a correlation between the terminology used in this guide and industry synonyms. Note that

37、 thesesynonyms are terms that are commonly used in the industry and, because many are not necessarily goodusage, they should therefore not be taken as equivalents to the guide terminology.For the purposes of this guide, the following terms and definitions apply.

44、n Wire Gage: Also known as the Brown and Sharp gage, the gage was devised in 1857 by J.R. Brown. This gage has the property such that its sizes represent approximately the successive steps in theprocess of wire drawing. Also, its numbers are retrogressive; a larger number denotes a smaller wire corr

45、e-sponding to the operations of drawing. These gage numbers are not arbitrarily chosen, but follow themathematical law upon which the gage is founded.3.1.12 anchor:A device that serves as a reliable support to hold an object firmly in place. The general term“anchor” is normally associated with cone,

46、 plate, screw, or concrete anchors. The terms snub, deadman, andanchor log are usually associated with pole stubs or logs set or buried in the ground to serve as temporaryanchors. The latter are often used at pull and tension sites. Syn:anchor log, deadman, andsnub.3.1.13 anchor log:Seeanchor.3.1.14
