The primary benefits of using bundle conductors, which consist of two or more conductors per phase, are rooted in their ability to improve electrical characteristics and increase power transfer efficiency. By effectively increasing the overall diameter of the conductor, bundling reduces the voltage gradient at the surface. This, in turn, significantly minimizes corona loss, which is a major source of power wastage and radio interference in high-voltage systems. Additionally, bundle conductors lower the line's inductance and increase its capacitance, which leads to a higher Surge Impedance Loading (SIL) and an increased power transfer capacity over long distances.
