Abstract

The present invention relates to a cooling apparatus for a medium voltage or high voltage switchgear, the cooling apparatus comprising:- an evaporator section;- a fluid conduit; and- a condenser section.The evaporator section is configured to surround at least part of a current carrying contact. The fluid conduit fluidly connects the evaporator section to the condenser section. A section of the fluid conduit is formed within the evaporator section and is electrically insulating and is configured such that fluid can contact an outer surface of the current carrying contact. The cooling apparatus is configured such that in use a working fluid in the evaporator section is heated to a vapour state, and the vapour is transferred by the fluid conduit to the condenser section. The vapour in the condenser section is condensed to the working fluid. The condensed working fluid is passively returned via the fluid conduit to the evaporator section.
