714,302. Cooling insulating-liquids for electrical apparatus. PHILIPS ELECTRICAL INDUSTRIES, Ltd. May 15, 1952 [May 18, 1951], No. 12300/52. Class 64(3) In high-voltage electrical apparatus in which liquid insulation 2 of the apparatus is cooled by a cooling liquid supplied through a pipe 4 extending through the top wall 1 of a casing enclosing the insulation, and flowing through an indirectcontact heat-exchanger immersed in the insulation, condensation of water from the air above the insulation 2 upon the pipe 4 is prevented by surrounding the pipe 4 by a hollow body 5. This body is united at the top to the wall 1, extends below the surface of the liquid insulation, and is closed at the bottom except for a passage for the pipe 4.
