An essential component of electrical transmission system engineering is the design of high voltage transmission conductors, which has an impact on affordability, dependability, and efficiency. The main elements affecting the design of high voltage transmission wires are examined in this abstract. The significance of elements like voltage capacity, electrical resistance, weight, durability, mechanical strength, resistance to corrosion, insulation, and cost-effectiveness is covered. These parameters have improved as a result of developments in materials science and engineering, which have made it possible to create high voltage conductors that can effectively transfer electricity over long distances and endure a variety of environmental difficulties. In order to satisfy the increasing demands of contemporary electrical transmission systems, the abstract emphasizes the necessity of ongoing research and development activities focused at improving the design and performance of high voltage transmission conductors.
