About this book

This CIGRE Green book on accessories for HV and EHV extruded cables covers relevant issues in cable system design, cable design, and submarine cables, including offshore generation connection. It provides comprehensive and unbiased information, essential recommendations and guidelines for design, installation, testing and maintenance of accessories to professionals through the exceptional expertise of the authors.

The publication is divided in two volumes covering land and submarine applications, HVAC and HVDC systems, andtransitions from lapped cable systems to extruded cable systems, from OHL to UG cables and from cables to substations. It equips the reader with recommendations for testing, installation, maintenance, and remaining life management. This volume is dedicated to Land and Submarine AC/DC Applications while Volume 1 deals with Components.

The book compiles the results of the work achieved by several Working Groups and Task Forces of CIGRE Study Committee 21/B1, and Joint Working Groups and Joint Task Forces with other Study Committees. Many experts from Study Committees 21/B1 (Insulated Cables), 15/D1 (Materials and Emerging Test Techniques), 33/B3 (Substations), C3 (System Environmental Performance), and C4 (System Technical Performance) have participated in this work in the last 30 years in order to offer comprehensive, continuous, and consistent outputs.

Frontmatter
1. Accessories in Underground Cable Systems and in Transitions from Overhead to Underground
Abstract
In many occasions in the previous chapters and especially in Chap.​ 2 “Guide to the Selection of Accessories,” the reader has been advised to consider the compatibility of the Accessory with the Cable (Sect. 2.2), and the compatibility of the Accessory Performance with that of the Cable System (Sect. 2.3).

2. Safe Work Under Induced Voltages or Currents
Abstract
During several phases of a cable system life (installation/maintenance/testing/upgrading/removal), it can be necessary to work under voltages or currents induced by an energized system. For example:

3. Long AC Extruded Submarine Cables: Recommendations for Testing Cables and Accessories
Abstract
This chapter of the book reproduces the Technical Brochure 490 Published in 2012 by CIGRE WG B1.27 convened by A. Gustafsson from Sweden.

4. Basics on Construction and Installation Methods
Abstract
At the beginning of the Working Group 21.17’s work, and before publication of TB 194, the difference was not very clear since both words were being used to define the same processes in a number of countries.

5. Recommendations for Mechanical Testing of Submarine Cables (and Their Accessories)
Abstract
This chapter, which reproduces Cigré TB 623 published by WG B1.43, convened by Marc Jeroense from Sweden, is divided into two principal parts: one part describes the general background of mechanical handling of cables throughout the life cycle and the general aspects of testing in relation to handling (Sects. 5.3 and 5.4); the other part describes the tests that are recommended or may be performed (Sects. 5.5 and 5.6).

6. Recommendations for Testing DC Extruded Cable Systems for Power Transmission at a Rated Voltage up to 500 kV
Abstract
In 2003 TB 219 “Recommendations for testing DC extruded cable systems for power transmission at a rated voltage up to 250 kV” was issued by Cigré study committee B1 (Cigré TB 219 2003). This was the first document issuing recommendations for testing of high voltage DC extruded cable systems. The recommendation was recognized by a large and relevant technical community and has become the reference for the user community. In 2008 it was decided by SC B1 to launch a new working group to prepare recommendations for testing DC extruded cables systems at a rated voltage up to 500 kV. The decision was motivated by the fact that commercially available HVDC extruded systems above 250 kV were emerging.

7. Recommendations for Testing DC Transition Joints for Power Transmission at a Rated Voltage up to 500 kV
Abstract
This Chapter is the editorial and graphical revision of the Cigré TB 622, prepared by WG B1.42 and published in June 2015. Gunnar Evenset, from Norway, was the Convener of the WG.

8. Sheath Bonding Equipment for AC Transmission Cable Systems
Abstract
This chapter contains the study outcome for sheath bonding of ac transmission cable systems. It comes from Technical Brochure 797 prepared by WG B1.50 and published in March 2020. The WG B1.50 was convened by T.ZHAO from the USA, The Technical lBrochure 797 (TB) incorporates design, testing (including after installation testing), and maintenance of these sheath bonding systems. Sheath bonding is required for all cable systems to ensure an effective bond to earth of the cable system metal sheath, armoring, and semi-conductive outer sheath covering. Incorrectly performed sheath bonding systems may lead to cable system failures or pose a human safety risk. Sheath bonding systems for the purpose of this chapter include related cable system components and equipment that are connected to form the required ac cable system sheath, armoring, and semi-conductive outer sheath bond and connection to earth.

9. Maintenance and Remaining Life
Abstract
This chapter partly reproduces the content of the Technical Brochure 825, published in early 2021 by the WG B1.60, convened by B. Mampaey from Belgium. The TB 825 contains numerous appendices that are not included in the chapter. As this book is dedicated to accessories for extruded cables and does not cover Fluid Filled cables, the part of the TB addressing lapped cables is not reproduced in this chapter.
