Abstract
The insulation of high-voltage cables plays a critical role in ensuring reliable power transmission and system longevity. Cross-linked polyethylene (XLPE) has emerged as a preferred insulation material due to its excellent dielectric properties, thermal stability, and mechanical strength. This study investigates the electrical characteristics of XLPE insulation in high-voltage cables, focusing on parameters such as dielectric strength, insulation resistance, partial discharge inception voltage, and breakdown behavior under varying electrical stresses and environmental conditions. Experimental evaluations were conducted using standardized test procedures to assess the performance of XLPE-insulated cables under AC and DC voltages, temperature variations, and moisture exposure. The results indicate that XLPE exhibits high dielectric strength and robust insulation resistance, making it suitable for modern high-voltage transmission systems. Furthermore, the study highlights the effects of aging and thermal stress on the electrical properties of XLPE, providing valuable insights for cable design, maintenance, and fault diagnosis. The findings contribute to the optimization of high-voltage cable performance and the enhancement of power system reliability.
