Abstract
A high voltage circuit breaker and disconnector for operation in air, extending along an axis, including an enclosure, the disconnector including a hollow current carrying conductor in the enclosure and extending along the axis. The conductor including at least one lower elongated slot and at least one upper elongated slot extending along the axis, each of the slots having a width w and a length l opening an air flow cross section. The ratio between the outer diameter surface of the hollow current carrying conductor and the total air flow cross section of all the slots in a same plane perpendicular to the axis being between 70 and 100.
