6、tandards Coordinating Committees of the IEEE Standards Board. Members of the committees serve voluntarily and without compensation. They are not necessarily members of the Institute. The standards developed within IEEE represent a consensus of the broad expertise on the subject within the Institute
7、as well as those activities outside of IEEE that have expressed an interest in participating in the development of the standard. Use of an IEEE Standard is wholly voluntary. The existence of an IEEE Standard does not imply that there are no other ways to produce, test, measure, purchase, market, or
8、provide other goods and services related to the scope of the IEEE Standard. Furthermore, the viewpoint expressed at the time a standard is approved and issued is subject to change brought about through developments in the state of the art and comments received from users of the standard. Every IEEE
9、Standard is subjected to review at least every five years for revision or reaffirmation. When a document is more than five years old and has not been reaffirmed, it is reasonable to conclude that its contents, although still of some value, do not wholly reflect the present state of the art. Users ar
10、e cautioned to check to determine that they have the latest edition of any IEEE Standard. Comments for revision of IEEE Standards are welcome from any interested party, regardless of membership affiliation with IEEE. Suggestions for changes in documents should be in the form of a proposed change of
11、text, together with appropriate supporting comments. Interpretations: Occasionally questions may arise regarding the meaning of portions of standards as they relate to specific applications. When the need for interpretations is brought to the attention of IEEE, the Institute will initiate action to
12、prepare appropriate responses. Since IEEE Standards represent a consensus of all concerned interests, it is important to ensure that any interpretation has also received the concurrence of a balance of interests. For this reason IEEE and the members of its technical committees are not able to provid
13、e an instant response to interpretation requests except in those cases where the matter has previously received formal consideration. Comments on standards and requests for interpretations should be addressed to: Secretary, IEEE Standards Board 445 Hoes Lane P.O. Box 1331 Piscataway, NJ 08855-1331 U

16、rom IHS -,-,- iii Introduction (This introduction is not a part of IEEE Std 525-1992, IEEE Guide for the Design and Installation of Cable Systems in Substations.) This revision of the guide incorporates various changes in cable installation philosophies that have occurred since the 1987 version of t
17、he guide. Significant changes have been made in the following areas: a)Conductor sizing and voltage rating of power cable in clause 3 was rewritten. b)Guidelines were added for the installation of optical cable. c)Maximum allowable pulling tension calculation methodology in clause 10 was rewritten.
18、In the 1992 IEEE style, notes in text are not a normative part of a standard. This standard makes an exception to that rule. In future revisions, this exception will not occur. This guide was prepared by the Wire and Cable Systems Working Group of the Substations Committee, Transmission Substations
19、Subcommittee. The following is a list of participants of the working group who were involved in this effort: A. E. Kollar, Chair G. R. Engmann, Vice Chair S. J. Arnot N. Barbieto M. J. Bogdan J.
