A New Unusual Bundle and Phase Arrangement For Transmission Line To Achieve Higher Natural Power

In conventional lines, subconductors are located symmetrically on an identical circle in each phase. The number of subconductors in a bundle, the radius of the bundle circle, and the radius of each subconductor, are chosen so that the maximum electric field strength on the sub conductors,
$E_{max}$
, is limited to the permissible field strength on the conductor surface,
$E_{p r},\left(E_{max } \leq\right. E_{pr})$
, which is determined by the corona discharge limitation requirement. In this paper, we show that by shifting phase configurations and subconductors into unusual/unconventional arrangements that are geometrically optimized within the space, high power density designs can be achieved. A novel bundle and phase arrangement of a 500 kV transmission line is presented in this paper, resulting in higher natural power than conventional design.
