Power cables serve the essential purpose of efficiently transporting and distributing electrical energy. It is crucial for this transportation and distribution process to be executed with a high level of reliability and safety over extended periods of time. Over the years, there has been a continuous increase in the range of voltage and capacity transmitted through cables. Several factors contribute to the rapid growth of cable technology, particularly in the extra-high-voltage range. These factors include environmental concerns, aesthetic considerations, limitations in establishing transmission corridors, and challenges associated with routing overhead lines in densely populated areas.
