Power Cables in Energy Systems

Dear Colleagues,

Power cables play a prominent role in power transmission at the global level, which are also likened to the "arteries" in energy systems. Nowadays, submarine cables used for offshore wind energy have further enriched this field. Therefore, various new technologies to improve the reliability of cable systems are particularly important, including but not limited to insulation technologies, design, testing and detection technologies, multiphysics simulation technologies, etc. In addition, we have also witnessed significant progress in the environmentally friendly insulation of power cables over the past decade. Therefore, this Special Issue aims to promote and disseminate recent advancements in theory, design, modeling, testing, and detection related to the application of power cables in energy systems.

In this Special Issue, original research articles and reviews are welcome. Research areas may include, but are not limited to, the following:

• Insulation materials for cables and accessories;
• Space charge characteristics;
• Partial discharge and breakdown;
• Environmentally friendly insulation;
• Insulation condition assessment;
• Condition monitoring for cable systems;
• Sensors and signal analysis;
• Lifetime prediction and reliability models;
• Cables used in harsh environment;
• Multiphysics simulation for cables and accessories;
• Novel technologies for submarine cable systems.

We look forward to receiving your contributions.

Abstract: This article presents the recent development in the field of evaluation of breakdown performance and remaining lifetime of XLPE. The effects of crystal morphology, thickness and sampling location of XLPE insulation on the evaluation of short-term breakdown performance are reviewed in the context of experiments. The study reviews the application of the Ramu, Simoni, Ramu multi-stress lifetime models and explores remaining lifetime prediction models under combined electro-thermal stress applicable to XLPE insulation. Finally, this paper puts forward the engineering evaluation methods and suggestions for the electrical performance of XLPE insulation for high voltage cables of XLPE insulation.
