Compared with a solid conductor of the same radius, corona appears on a stranded conductor at a lower voltage, because stranding
1
assists ionization
2
makes the current flow spirally about the axis of the conductor
3
produces oblique sections to a plane perpendicular to the axis of the conductor
4
produces surfaces of smaller radius
