Interaction between cable and accessory materials in HVAC and HVDC applications
High voltage cable systems consisting of the cable itself and of accessories must be compatible during the lifetime of the system electrically, thermally, and thermo-mechanically. The JWG presents a systematic overview of insulation interfaces in cable accessories and possible failure modes associated with these interfaces.
The main parameters affecting compatibility are discussed and their effect in AC and DC operation is analysed. A guideline and possible set-ups for development testing are proposed, and additional tests as well as enhanced documentation during and after qualification are presented.
Finally, a new composite parameter for evaluating insulation interfaces is introduced.
This webinar is presented by Anders Gustafsson & Alexander Hergert, conveners of CIGRE Joint Working Group SCB1/D1.75, together with Oystein Hestad, Dominik Häring & Isabella Nett, members of this JWG.
Their Technical Brochure 968 (available on eCIGRE), was published in 2025.
Registration to this webinar is free for all. Technical Brochures, can be freely downloaded by CIGRE members. If you are not a CIGRE member, join CIGRE
