IEEE Std 532:2021 pdf download.IEEE Guide for Selecting and Testing Jackets for Power, Instrumentation, and Control Cables.
This guide covers the selection and testing of jackets for power, instrumentation, and control cables. It is written for those responsible for optimizing cable design and performance. The purpose is to present a reasonably complete picture of the role of jackets 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 ofjackets.
1.2 Purpose
The purpose of this guide is to provide cable users guidance in the selection of jackets 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 Word usage
The word s/ia/I indicates mandatory requirements strictly to be followed in order to conform to the standard and from which no deviation is permitted (shall equals is required to).
The word should indicates that among several possibilities one is recommended as particularly suitable, without mentioning or excluding others: or that a certain course of action is preferred but not necessarily required.
The word may is used to indicate a course of action permissible within the limits of the standard (ma3’ equals is permitted to).
The word can is used for statements of possibility and capability, whether material, physical, or causal (can equals is able to).
1.4 General historical perspective
Various compounded textile sandwich-type coatings were the predominant jackets used up to and into the 1 950s. Experience has indicated that the electrical resistivity required to effectively isolate the metallic sheath or shield, or both, from their environment could not be satisfied by these jackets. In many situations, the dielectric integrity of the jacket is more important than the resistivity.
Factors that influenced improvement ofjackets for cable sheaths/shields include the following:
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 cathod ical ly.
c) The use of metals (tinned copper, brass, or steel) to reinforce lead sheaths requiring ajacket 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) It is desirable that the sheath/shield be isolated from its environment.
0 Practices to reduce electrical losses by minimizing circulating sheath/shield currents result in the appearance of voltages on the sheath/shield; under transient conditions, these voltages may be substantial.
