Introduction This introduction is not part of IEEE Std 532-2007, IEEE Guide for Selecting and Testing Jackets for Power, Instrumentation, and
7、 Control Cables. This guide is concerned with jackets as they are defined in The Authoritative Dictionary of IEEE Standards, Seventh Edition (“A thermoplastic or thermosetting plastic covering, sometimes fabric reinforced, applied over the insulation, core, metallic sheath, or armor of a cable”). Us
8、ers should note that this guide makes reference to standards developed by the Insulated Cable Engineers Association (ICEA), the Association of Edison Illuminating Companies (AEIC), and other organizations. This guide is written to provide cable users guidance in the selection of jackets and protecti
9、ve covers for the purpose of optimizing cable design. A secondary purpose is to present a reasonably complete picture of the types and functions of jackets so that the user can approach the subject in an orderly and logical manner. An effort has been made to avoid the highly technical language and t
10、heory commonly used by electrical engineers and chemists to discuss the more detailed application of jackets. As a result, the various topics covered in this guide are not necessarily exhaustive in every respect. This guide provides recommendations for the properties, characteristics, design, and te
11、sting of various types of cable jackets. It is the intent of this guide to ensure that jacket materials are suitably specified for their intended applications. Also, jackets should provide a level of electrical, thermal, mechanical, and chemical durability to ensure that cable performance is reliabl
12、e under normal use and should reduce the danger to the user or surroundings. The users of this guide are cautioned that all data contained herein are presented for information purposes only. Where deemed necessary, additional, as well as more detailed, information should be obtained by consultation
13、with the cable manufacturer and other experts in the field.

37、s. 1.1 Scope This guide covers the selection and testing of jackets and other protective coverings for power, instrumentation, and control cables. It is written for those individuals responsible for optimizing cable designs. The purpose is to present a reasonably complete picture of the role of jack
38、ets so that the subject can be approached in an orderly and organized manner. An effort has been made to avoid the highly technical language and theory commonly used by electrical engineers and chemists to discuss the more detailed application of jackets. 1.2 Purpose The purpose of this guide is to
39、provide cable users guidance in the selection of jackets and protective covers to optimize cable design. A secondary purpose is to present a reasonably complete picture of the types and functions of jackets so that the user can approach the subject in an orderly and logical manner. 1.3 General histo
40、rical perspective Various compounded-textile sandwich-type coatings were the predominant jackets used up to and into the 1950s. Experience has indicated that the electrical resistivity required to isolate effectively the metallic sheath or shield, or both, from their environment could not be satisfi
41、ed by these jackets. In many situations, the dielectric integrity of the jacket is more important than the resistivity. IEEE Std 532-2007 IEEE Guide for Selecting and Testing Jackets for Power, Instrumentation, and Control Cables 2 Copyright 2008 IEEE. All rights reserved. Factors that influenced im
42、provement of jackets for cable sheaths/shields include: a) Consideration of the destructive effects of galvanic and electrolytic corrosion. b) The use of amphoteric metals (lead or aluminum) for cable sheaths, which are difficult to protect cathodically. c) The use of metals (tinned copper, brass, o
43、r steel) to reinforce lead sheaths requiring a jacket that would reliably protect the pressure-retaining metallic components from deterioration when placed in earth or ducts. d) The introduction of aluminum-sheathed cables requiring a protective jacket of good mechanical and dielectric properties. e
44、) The use of single-conductor cable systems that, by their nature, involve induced voltages on the sheath/shield (see Eaton and Issa B61and Kellam B9). It is desirable that the sheath/shield be isolated from its environment. f) Practices to reduce electrical losses by minimizing circulating sheath/s
45、hield currents result in the appearance of voltages on the sheath/shield (see Halperin et al. B7, Halperin and Miller B8, and Watson and Erven B11); under transient conditions, these voltages may be substantial. 2.
