Sheath Bonding systems of AC transmission cablesWed, Apr 20, 2022 1:00 PM - 3:00 PM CEST


Most ground cable AC systems will have Sheath bonding systems, this has been covered in various CIGRE working groups as part of other Technical Brochures (TB). The WG B1.50 was set up to collect all available information and issue a TB with the recent developments and best practices in the industry.


The TB contains overview of different technologies and strategies that are employed. Cable models for calculating design parameters. Details in design of components and methods such as:


  • Solid/multi-point/single and mid-point bonding
  • Cross bonding (ground and tunnel installation)
  • Impedance bonding
  • Siphon lines
  • Sheath Voltage Limiters, connections and installations


Testing and maintenance of bonding systems are also covered in addition to appendix with service experiences and survey from users.
