Section insulators are crucial components in overhead railway lines for ensuring the safe and efficient operation of electrified railway systems. This paper presents a comprehensive study aimed at investigating the mechanical forces acting upon section insulators and evaluating their electrical creepage distance in the context of a 25 KV overhead traction line phase change. The analysis leverages the computational capabilities of COMSOL Multiphysics to provide a detailed examination of these critical aspects.

Mechanical forces on section insulators play a vital role in maintaining their structural integrity and preventing mechanical failure. This study employs COMSOL Multiphysics to simulate and analyze the mechanical forces exerted on section insulators under varying conditions, including environmental factors and operational loads. The results of this analysis provide valuable insights into the mechanical stability and durability of section insulators, aiding in their design and placement optimization.

Furthermore, the electrical performance of section insulators is crucial for maintaining the electrical isolation between different phases of the overhead traction system. To assess their electrical behavior, this paper investigates the creepage distance of section insulators when subjected to the demanding voltage and environmental conditions of a 25 KV overhead line. COMSOL Multiphysics is employed to model and analyze the electric field distribution along the insulator surface, enabling a thorough assessment of their electrical performance and safety margins.

By combining mechanical and electrical analyses, this research contributes to the improved understanding and design of section insulators in overhead railway lines. The findings will be instrumental in enhancing the reliability, safety, and efficiency of electrified railway systems, ultimately benefiting both operators and passengers.
