Abstract
A power cable to be provided inside a steel pipe that is electrically connected to a reference potential node, includes 3 transmission cables, 3 ground buses making contact with outer peripheral surfaces of adjacent transmission cables and arranged at 3-fold rotationally symmetrical positions with respect to a center of the transmission cables in a cross sectional view, a binder covering the ground buses and the transmission cables, and a jacket provided to overlap the binder. The transmission cables have outer diameters to inscribe a first circle having a radius corresponding to a radius of a second, envelope circle of the power cable having a maximum radius inside the steel pipe, but excluding thicknesses of the binder and the jacket. The ground buses have outer diameters to project outwardly of an envelope closed curve of the transmission cables, but less than or equal to a diameter of the first circle.
