ABSTRACT:
A coolant displacement material for a liquid cooled transformer consisting of a plurality of glass spheres having one or more closed voids to provide a specific gravity which is greater than oil so that the glass spheres remain submerged without need for securing devices and is substantially less than the specific gravity of solid glass material so as to not unnecessarily contribute to the weight and consequent shipping cost of the coolant displacement material and the completed transformer assembly. The spheres provide venturi-like flow passages which enhance thermal transfer between the transformer and the coolant by increasing the flow velocity of the coolant to break down surface-effect thermal barriers. The glass spheres are sufficiently small in size to conform to a substantial portion of the space between the transformer and tank. The wall thickness of the spheres at their exterior surface is sufficiently great so that the glass spheres are substantially non-disintegrating during loading of the spheres into the tank.
