A METALLIZED FILM CAPACITOR ELEMENT COMPRISING THERMALLY CONDUCTIVE FILMS AND A THERMALLY CONDUCTING FILM FOR AN ELECTRICAL POWER COMPONENT

摘要

The present invention relates to a metallized film capacitor element comprising a plurality of concentrically arranged cylindrical sub-elements (3a-c), each sub-element including at least one metal coated dielectric film wound in a plurality of turns. The capacitor element further comprises one or more thermally conductive sections (4a-b) provided between the sub-elements. Each of the thermally conductive sections includes a sheet wound at least one turn and having a higher thermal conductivity than the metal coated dielectric film of the sub-elements. The second invention also relates to a thermally conducting film for improving the thermal conductivity of electrical power components. The thermally conducting film comprises an electrically insulating film and thermally conductive and electrically insulating particles disposed on at least one side of the film.
