The present invention relates to a power capacitor for high voltage and comprises at least one capacitor element (2a-2d). The object is to achieve a capacitor with improved electrical properties and which allows simple manufacture. According to the invention, each capacitor (2a-2d) has a substantially circular-cylindrical shape. The inside of the container (1) has a corresponding shape so as to closely surround each capacitor element (2a-2d). In addition, each capacitor element (2a-2d) is oriented with the axial direction coinciding with the axial direction of the container. The invention also relates to a capacitor bank (12) comprising a plurality of power capacitors of the invented kind, and to uses of one or more of the invented power capacitors as a component in electrical installations.
A power capacitor for high voltage comprising at least one capacitor element (2a-2d) enclosed in a container (1), characterized in that each capacitor element has a substantially circular-cylindrical shape and the inside of the container (1) has a corresponding substantially circular-cylindrical shape so as to closely surround each capacitor element (2a-2d), each capacitor element is oriented with the axial direction coinciding with the axial direction of the container, the container (1) being of electrically insulating material and provided with an electrical connection terminal (3, 4) arranged at each end of the container (1), whereby the container itself constitutes insulation between the connection terminals.
