(This introduction is not part of IEEE Std 635-2003, IEEE Guide for Selection and Design of Aluminum Sheaths for Power Cables.)

This guide is concerned with the selection and design of aluminum sheaths for low-, medium-, high-, and extra high-voltage power cables. An aluminum sheath is defined as "an impervious aluminum or aluminum alloy tube, either smooth or corrugated, which is applied over a cable core to provide mechanical protection." It may or may not have a jacket. Users may note that this guide makes reference to standards developed by other organizations. These references are useful for understanding the content of the guide.

The guide is written for those persons with responsibilities for installing and using cable with an aluminum sheath. The purpose of the guide is to establish design guidelines, basic installation, and use parameters. References and a bibliography related to the subject are also provided.

The guide is aimed at providing more detail for the application of aluminum sheaths. However, the topics covered in this guide are not exhaustive in every aspect of cable sheath design or performance.

The guide represents the work of Working Group A15W of Subcommittee A of the Insulated Conductors Committee, Power Engineering Society. Grateful acknowledgement is given to the individuals who contributed to the revision of this guide. This is the second revision to this guide originally issued in 1980 and revised in 1989.

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 with the cable manufacturer and other experts in the field.

Scope

This guide covers power cables incorporating an aluminum sheath, except those of the SF ₆ rigid-bus type
