ABSTRACT:
A gas insulated electrical apparatus in which electric devices for three phases are housed within a common gas-filled vessel includes a first and a second curved wall spaced apart from each other by a first distance and a third and a fourth curved wall connected between the first and second curved walls and spaced apart from each other by a second distance smaller than the first distance to define a substantially oval cross-sectional shape. The electric devices are arranged in a row extending between the first and second walls. The first and second curved walls may have a first radius of curvature and the third and fourth curved walls may have a second radius of curvature larger than the first radius of curvature.
