Summary:The present invention relates to a power capacitor of the type described in the preamble to claim . The power capacitor in accordance with the invention is primarily intended for a rated voltage exceeding 1 kV, e.g. 5 kV, preferably at least 10 kV. A power capacitor for high voltage including at least one capacitor element enclosed in a container, use of a gel in such a capacitor, and a method for manufacture of the capacitor. A space is formed between each capacitor element and the container. The power capacitor can handle problems concerning oil leakage in such a capacitor. In the power capacitor the space is filled up by a dielectric fluid including a gelling component. Because a gel is used instead of oil, the risk of oil leakage is eliminated.
