Abstract - 4,228,318 Patent
A method and means are disclosed for dissipating heat in a high voltage cable termination which includes a plurality of axially stacked annular capacitor elements disposed coaxially over the prepared end of a high voltage cable and disposed within an annular insulator so that a temperature gradient normally exists radially across the capacitor elements. A thermally and electrically conductive annular disc is interposed between each adjacent pair of stacked capacitors for dissipating heat from the area inwardly of the capacitors to the area outwardly thereof. The conductive discs enable a significantly greater increase in terminator ampacity, and may be employed in both AC and DC high voltage systems.
